Getting Started: Ordering Your Hetzner Server

Alright, guys, now that you're totally hyped about the awesome potential of a Hetzner Windows server, let's talk about the super important first step: ordering your server! Don't sweat it; the process is pretty straightforward, but there are a few key things to keep in mind to make sure you get exactly what you need for your Windows server setup. First, head over to the Hetzner website. You'll want to navigate to their "Dedicated Servers" section. They offer a few different lines, like "EX," "AX," "PX," and "SX," which generally denote different processor types (Intel Xeon, AMD Ryzen, etc.) and overall hardware configurations. This is where your personal needs and budget really come into play. Are you planning to run a demanding database, a heavily trafficked web application, or just a simple remote desktop for a few users? Your intended use case will heavily influence the specifications you should look for. For a solid Windows server setup, you'll typically want at least 16GB of RAM, especially if you're running any kind of database or virtualized applications, and a decent multi-core processor. Remember, Windows Server can be a bit more resource-hungry than some Linux distributions, so a little extra horsepower goes a long way in ensuring a smooth and responsive experience. The storage is also crucial; NVMe SSDs are highly recommended for their incredible speed, which will significantly improve boot times and application performance.

Once you've zeroed in on a server model that catches your eye and fits your requirements, you'll proceed to the configuration page. This is where you make crucial decisions for your Hetzner Windows server setup. You'll typically have options for storage configuration (e.g., single NVMe, RAID 1 with two drives), additional IP addresses (useful for multiple services or domains), and, most importantly for us, the operating system. While Hetzner often defaults to various Linux distributions, you'll need to look for the "Windows Server" option. They usually offer several versions, such as Windows Server 2016, 2019, or 2022, sometimes even specific editions like Standard or Datacenter. Be sure to select the version that best suits your licensing needs and application compatibility. Keep in mind that Windows Server licenses incur an additional monthly fee, which will be clearly displayed. This is a standard practice for dedicated server providers. Don't forget to review all the selected options carefully before proceeding to checkout. Double-check the RAM, CPU, storage, and especially the Windows Server version. You want to make sure your Hetzner Windows server setup starts on the right foot with the correct foundation. After you've confirmed everything, you'll go through the account creation and payment process. Once your order is placed and processed, Hetzner usually provisions dedicated servers quite quickly, often within a few hours, depending on the current demand and server availability. You'll receive an email notification when your server is ready for initial setup. This email will contain important details, including your server's IP address and login credentials for the Hetzner Robot panel – your command center for managing your new Hetzner Windows server. This panel is super powerful and will be essential for the next steps in our Windows server setup journey!

Picking the Right Server Model

Alright, let's talk about picking the right server model for your Hetzner Windows server setup. This isn't just about grabbing the cheapest or most expensive option; it's about finding that sweet spot that meets your needs without breaking the bank. Hetzner's server offerings are generally categorized by processor type and generation. For instance, the "EX" line often features Intel Xeon CPUs, known for their reliability and core count, making them great for virtualization or heavy multi-threaded workloads. The "AX" series typically utilizes AMD Ryzen processors, which offer incredible value with high core counts and clock speeds, perfect for general-purpose computing, game servers, or even some video processing. The "PX" line might feature more premium Intel options, while "SX" could be storage-optimized.

When you're evaluating models for your Windows server setup, here are some key specs to consider:

  • CPU Cores and Clock Speed: More cores are generally better for multitasking and running multiple applications simultaneously. Higher clock speeds are good for single-threaded performance, which some applications still heavily rely on. For a typical Windows server setup, aim for at least 4-6 cores, but 8+ is fantastic if your budget allows.
  • RAM (Memory): This is crucial for Windows Server. Windows itself and its common roles (like Active Directory, SQL Server, IIS) consume a fair bit of RAM. We recommend a minimum of 16GB RAM for any serious Hetzner Windows server setup. If you plan on running databases, multiple web applications, or virtual machines, 32GB or even 64GB will give you much more breathing room and prevent performance bottlenecks.
  • Storage (Disks): Always go for SSDs, specifically NVMe SSDs, if available and within your budget. The performance difference between traditional HDDs and NVMe SSDs is like night and day, drastically impacting boot times, application load times, and overall system responsiveness. Consider if you need RAID (Redundant Array of Independent Disks) for data redundancy. RAID 1 (mirroring) means two drives store identical data, so if one fails, your data is safe. This is a smart choice for critical data, even if it means sacrificing some usable storage capacity.
  • Network Port Speed: Most Hetzner servers come with a 1 Gbit/s network port, which is generally ample. Some higher-end models might offer 10 Gbit/s, which is awesome if you anticipate extremely high network traffic, like for a very busy web server or large data transfers.

Think about your future needs too! It's often smarter to slightly overprovision your server initially rather than finding yourself needing an upgrade just a few months down the line. Upgrading a dedicated server typically means migrating data to a new machine, which can be a hassle. A little foresight here will save you headaches in your Hetzner Windows server setup journey!

Selecting Your Windows OS Version

Choosing the right Windows OS version for your Hetzner Windows server setup is another critical decision, guys. Hetzner typically offers a selection of the most common Windows Server versions, usually including the last few major releases like Windows Server 2016, 2019, and 2022. Each version has its own features, improvements, and crucially, lifecycle support from Microsoft.

Here’s a quick rundown to help you decide:

  • Windows Server 2022: This is the latest and greatest, offering enhanced security features, improved hybrid cloud capabilities with Azure, and better container support. If your applications are compatible and your budget allows, this is generally the recommended choice for a new Hetzner Windows server setup as it provides the longest support lifecycle and the most modern features.
  • Windows Server 2019: Still a very solid and widely used option. It introduced significant improvements in container support, WSL (Windows Subsystem for Linux), and storage. Many businesses still run on 2019, and it will be supported for quite some time. It's a great balance of features and maturity.
  • Windows Server 2016: While older, it's still supported (though mainstream support might be ending or already ended for some editions, check Microsoft's lifecycle page). You might only choose this if you have legacy applications that specifically require 2016 for compatibility reasons. For new deployments, it's generally best to avoid older versions unless absolutely necessary.

Beyond the version number, you might also see options for Standard or Datacenter editions.

  • Standard Edition: Perfect for most use cases, allowing you to run two virtual machines (VMs) or two Hyper-V containers. This is usually sufficient for a single dedicated server where you might run a few applications directly or within a couple of VMs.
  • Datacenter Edition: More expensive, but offers unlimited virtual machines/Hyper-V containers. It also includes advanced features like Storage Spaces Direct and shielded virtual machines. For a dedicated server, this is usually overkill unless you're planning to run a highly virtualized environment with many VMs.

For the vast majority of Hetzner Windows server setup scenarios on a single dedicated server, the Standard Edition of Windows Server 2019 or 2022 will be your best bet. Always consider your software requirements and future expansion plans when making this choice. Remember, the license cost is recurring, so factor that into your monthly budget!

The Initial Setup Process: From Order to Login

Okay, guys, you've placed your order, picked your awesome server, and selected your Windows OS version for your Hetzner Windows server setup. What happens next? You'll typically receive an email from Hetzner confirming your server is ready, complete with its primary IP address and, crucially, access details for the Hetzner Robot panel. This panel is your control center, and it's where the real magic of installing Windows begins. Now, unlike some cloud providers where you just click "install Windows" and it's magically ready, with Hetzner dedicated servers, there's a slightly more manual (but totally empowering!) process involved. The reason is that Hetzner provides you with raw hardware; they don't pre-install a full Windows OS directly. Instead, they give you the tools to install it yourself, which ultimately gives you more control and a deeper understanding of your server. This process usually involves booting into a special Linux-based rescue system, mounting a Windows ISO, and then using a KVM-over-IP console to perform the actual graphical installation. Don't let that sound intimidating; we'll break it down.

First things first, log into your Hetzner Robot panel using the credentials provided in your email. Once you're in, navigate to your specific server. Here, you'll find various tabs like "Main," "IPs," "Network," and "Rescue." Your first mission for your Hetzner Windows server setup is to activate the Rescue System. This is a minimalist Linux environment that boots over the network (PXE boot) and allows you to prepare your server for the Windows installation. Go to the "Rescue" tab, select the architecture (usually 64-bit), and activate it. You'll be given a temporary root password for this rescue system. Once activated, head back to the "Main" tab and initiate a "Reset" or "Reboot" of your server. This will cause your server to boot into the rescue system. Give it a few minutes. You'll then be able to connect to the rescue system via SSH using the temporary credentials. From within the rescue system, you'll use a utility (often installimage or similar, but for Windows, you'll primarily need to set up the environment for the ISO) to prepare the server, download the Windows ISO (Hetzner typically provides a list of direct links to official Windows Server ISOs within the Robot panel's "Install" tab or a similar section), and then crucially, prepare the KVM/IPMI console. The KVM console is essentially a virtual monitor, keyboard, and mouse that allows you to interact with your server as if you were sitting right in front of it, even before an operating system is fully installed. This is absolutely essential for performing the graphical Windows installation. So, while it seems like a few extra steps compared to a fully managed solution, this method provides immense control and flexibility, which is a huge advantage for serious server administration.

Accessing the KVM/IPMI Console

The KVM/IPMI console is your best friend during the initial Hetzner Windows server setup, especially when you're installing the operating system. Think of it as a virtual window into your server's BIOS, boot process, and the graphical installer itself. To access it, after you've activated the rescue system and it's rebooted, head back to your server's page in the Hetzner Robot panel. Look for a section related to "KVM Console" or "Remote Console." Hetzner uses something called LARA or HTML5 KVM for many of their newer servers, which typically provides a web-based, Java-free KVM connection directly in your browser. For older servers, you might need to use a Java-based iKVM viewer. Follow the instructions provided in the Robot panel to launch this console.

Once the KVM console is open, you'll see your server's boot process. Since you've rebooted into the rescue system, you should see the Linux command line. Now, here's the trick: from the rescue system, you'll need to prepare the environment to mount your Windows ISO and make it bootable via the KVM. Hetzner often provides a script or documentation on how to do this. The general idea is to download the Windows ISO directly to your server's hard drive (using wget in the rescue system), then use a tool like qemu (which is often pre-installed or easily installable in the rescue system) to emulate a virtual CD-ROM drive and boot from that ISO via the KVM. This effectively "fools" your server into thinking it's booting from a Windows installation disc. This step is critical because without the KVM, you wouldn't be able to interact with the graphical Windows installer. It's a powerful tool that gives you direct, low-level access, which is invaluable for any troubleshooting or advanced configuration during your Hetzner Windows server setup.

Installing Windows Server OS

With the KVM console open and your Windows ISO prepared to boot, you're now ready for the actual Windows Server OS installation – this is where your Hetzner Windows server setup really comes to life! You'll initiate a reboot from the rescue system (often through the Robot panel or a command in the rescue system like reboot). As the server restarts, keep an eye on the KVM console. You should see the familiar "Press any key to boot from CD or DVD..." prompt. Quickly hit a key to ensure it boots from your virtual Windows ISO.

The rest of the installation process will be very similar to installing Windows on any physical computer:

  1. Language and Regional Settings: Choose your preferred language, time, and keyboard layout.
  2. Install Now: Click this button.
  3. Product Key: You'll be prompted for a product key. You can usually click "I don't have a product key" and activate Windows later using the license key provided by Hetzner (or your own if you brought one). Hetzner usually provides generic keys during installation which convert to the correct license upon activation.
  4. Operating System Selection: Choose the specific edition of Windows Server you want to install (e.g., Standard, Datacenter, with or without Desktop Experience). For most users, "Windows Server Standard (Desktop Experience)" is recommended as it provides the familiar graphical interface.
  5. License Terms: Accept the EULA.
  6. Installation Type: Select "Custom: Install Windows only (advanced)".
  7. Drive Partitioning: This is a crucial step. You'll see your server's hard drives. You'll typically want to delete any existing partitions (especially if you just received a new server or are reinstalling) and then create a "New" partition for your OS. Windows will usually create a few small system partitions automatically along with your main drive. Allocate the full disk space for your main OS drive, or partition it as you see fit. Be absolutely certain you're selecting the correct physical disk if you have multiple drives. Format the new partition.
  8. Installation: Windows will now copy files and install the operating system. This will take some time, and the server will reboot multiple times. Keep the KVM console open and monitor the progress.
  9. Initial Configuration: After the final reboot, you'll be prompted to set an administrator password. Make sure it's a strong, complex password!

Once the installation completes and you log in for the first time via the KVM, your Hetzner Windows server setup is nearing completion. You'll be greeted by the Windows Server Desktop. Congratulations, you've successfully installed Windows! Now, it's time for the post-installation essentials.

Post-Installation Essentials: Securing and Optimizing

Alright, champions, you've successfully navigated the Hetzner Windows server setup and your Windows Server is up and running – give yourselves a pat on the back! But guess what? The journey isn't over yet. The first boot into your new server through the KVM console is just the beginning. Now comes the crucial phase of post-installation essentials, which includes securing your server, getting it ready for remote access, and installing all the necessary updates and drivers. Trust me, skipping these steps is like leaving your front door wide open; it's just asking for trouble. Our goal here is to make your Hetzner Windows server not just functional, but also rock-solid and secure. The very first thing you'll want to do is enable and configure Remote Desktop Protocol (RDP). This is how you'll primarily interact with your server from now on, without needing to mess with the KVM console every time. From the KVM, open Server Manager, navigate to "Local Server," and enable Remote Desktop. Make sure the firewall rules are configured to allow RDP connections (port 3389 by default, though we'll talk about changing that later for security). Before you disconnect from the KVM and attempt your first RDP connection, test it thoroughly. Try connecting from your local machine using a remote desktop client to ensure everything is working as expected. If you can't connect, you'll be glad you still had the KVM open!

Once you've confirmed RDP access, the next critical step for your Hetzner Windows server setup is to make sure your server is fully updated and has all the correct drivers. Windows Server, like any OS, needs regular updates for security patches, bug fixes, and performance improvements. Go to "Settings" -> "Update & Security" -> "Windows Update" and check for updates. Be prepared for multiple rounds of updates and reboots. This can take some time, so be patient, guys. While Windows usually handles most drivers automatically, it's a good idea to check Device Manager (right-click Start button -> Device Manager) for any missing drivers, especially for network adapters or storage controllers. Sometimes, specific drivers for the virtualized environment (like VirtIO drivers, though less common with dedicated servers and Windows, it's good to be aware) might be needed for optimal performance. Hetzner often provides specific driver ISOs or links if required, so check their documentation for your specific server model if you notice any yellow exclamation marks in Device Manager.

After updates, it's time to batten down the hatches with firewall configuration. Windows Defender Firewall is enabled by default, which is great, but you need to ensure it's configured correctly for your specific use case. By default, it might block inbound connections you need. For example, if you're hosting a web server, you'll need to allow inbound traffic on ports 80 (HTTP) and 443 (HTTPS). If you're running a game server, you'll need to open its specific ports. Never open ports you don't absolutely need! A good practice is to only allow RDP from specific IP addresses if possible, rather than from anywhere on the internet. This significantly reduces your server's attack surface. Lastly, consider installing basic security software, such as an antivirus if you're not relying solely on Windows Defender, and implement strong password policies. Regularly backing up your data is also crucial; plan a robust backup strategy from day one of your Hetzner Windows server setup. These proactive steps will save you a lot of headaches down the line and ensure your Hetzner Windows server remains a secure and reliable workhorse.

Securing Your RDP Connection

Securing your Remote Desktop Protocol (RDP) connection is absolutely paramount for your Hetzner Windows server setup. RDP is a prime target for attackers because it offers direct graphical access to your server. Here’s how you can make it much safer:

  1. Change the Default RDP Port: By default, RDP uses port 3389. Attackers constantly scan for this port. Changing it to a non-standard port (e.g., something obscure like 54321, but pick your own unique number) makes your server less visible to automated port scans. You can do this via the Registry Editor (regedit.exe) at HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\PortNumber. Remember to update your Windows Firewall rules to allow the new port and also specify the new port when connecting from your RDP client (e.g., your_server_ip:54321).
  2. Strong Passwords & User Accounts: This goes without saying, but use extremely strong, unique passwords for all administrator accounts. Consider creating a separate, non-administrator user account for day-to-day RDP access and only elevate to admin when absolutely necessary.
  3. Firewall Rules - IP Restriction: The most effective security measure is to restrict RDP access to only your trusted IP addresses. In Windows Defender Firewall with Advanced Security, create an inbound rule for your RDP port (new or default) and under "Scope," specify "Remote IP addresses" and add your home/office IP(s). This is a game-changer for security. If your IP address changes frequently, consider using a VPN or a small cloud VM as a jump box.
  4. Account Lockout Policy: Configure an account lockout policy. This will temporarily lock out users after a certain number of failed login attempts, preventing brute-force attacks. You can find this in Local Security Policy (secpol.msc) under "Account Policies" -> "Account Lockout Policy."
  5. Network Level Authentication (NLA): Ensure NLA is enabled. This requires users to authenticate before a full RDP session is established, adding an extra layer of security and protecting against certain types of attacks. It's usually enabled by default on modern Windows Servers.
  6. Two-Factor Authentication (2FA): For the ultimate RDP security, consider implementing 2FA. Solutions like Duo Security or Azure MFA can be integrated to require a second factor (like a code from an app or a hardware token) in addition to the password. This makes your Hetzner Windows server setup incredibly robust against unauthorized access.

Implementing these steps significantly hardens your RDP connection, making your Hetzner Windows server much more secure against common threats.

Essential Windows Updates and Drivers

Once your Hetzner Windows server is accessible via RDP, the very next thing on your Hetzner Windows server setup checklist, without question, is to handle essential Windows updates and drivers. Think of it as giving your server its much-needed health check and inoculations right after birth.

  1. Windows Updates: Windows Server receives regular updates that are critical for security, stability, and performance.

    • Navigate to Start -> Settings -> Update & Security -> Windows Update.
    • Click "Check for updates."
    • Be prepared for this to be an iterative process. You might need to check for updates, install them, restart the server, and then check for updates again several times until no more updates are found. This is normal, especially after a fresh installation.
    • Ensure "Delivery Optimization" is off if you're concerned about bandwidth, though it's usually not a huge issue for dedicated servers.
    • Consider setting active hours or a maintenance window for automatic restarts to avoid unexpected downtime.

  2. Driver Installation and Verification: While Windows Server is generally good at identifying and installing drivers, sometimes dedicated server hardware benefits from specific drivers.

    • Open Device Manager (Right-click Start button -> Device Manager).
    • Look for any devices with yellow exclamation marks. These indicate missing or improperly installed drivers.
    • For dedicated servers, ensure your network adapters, storage controllers (especially if you configured RAID), and any other specialized hardware have the correct drivers.
    • Hetzner might provide a link to a driver ISO or specific drivers for their hardware within the Robot panel or their documentation. If you have yellow marks, this is your first stop.
    • Sometimes, installing the latest chipset drivers from the CPU manufacturer (Intel or AMD) can also slightly improve performance.

Why are these so important?

  • Security: Many updates patch critical security vulnerabilities that, if left unaddressed, could leave your server open to attacks.
  • Stability: Updates fix bugs and improve the overall stability of the operating system.
  • Performance: Sometimes, driver updates or OS patches can even yield performance improvements, making your Hetzner Windows server run more efficiently.

Don't skip this step, guys! A fully updated and properly driver-configured server is a happy, secure, and performant server, which is exactly what we're aiming for with your Hetzner Windows server setup.

Firewall Configuration and Best Practices

Your Hetzner Windows server setup needs a robust firewall configuration to protect it from the wild west of the internet. The Windows Defender Firewall, enabled by default, is actually quite powerful, and with the right settings, it can be your server's first line of defense. Here are the best practices:

  1. Understand the Basics: The firewall controls what traffic can come into (inbound rules) and go out of (outbound rules) your server. For security, we're primarily concerned with inbound rules, ensuring only necessary traffic is allowed in.
  2. Start with a Strong Default: Windows Defender Firewall generally has a good default, blocking most unsolicited inbound connections. Never disable it entirely.
  3. Only Open Necessary Ports: This is the golden rule. For your Hetzner Windows server:
    • RDP (Remote Desktop Protocol): You'll need this open. If you changed the default port (e.g., 54321), open that port. Ideally, restrict it to specific source IP addresses (as discussed in securing RDP).
    • HTTP (Port 80) / HTTPS (Port 443): If you're hosting a web server (IIS, Apache, Nginx), these ports must be open for external access.
    • Application-Specific Ports: Any other applications you run (e.g., SQL Server, game servers, VPN servers) will require their specific ports to be open. Consult the application's documentation.
    • Avoid opening common attack ports like Telnet (23), FTP (21, 20 if active), NetBIOS (137-139, 445) unless absolutely critical and secured with other means.
  4. How to Configure Rules:
    • Go to Start -> Search for "Windows Defender Firewall with Advanced Security" and open it.
    • In the left pane, select "Inbound Rules."
    • To create a new rule, click "New Rule..." in the right-hand "Actions" pane.
    • Choose "Port," then specify "TCP" or "UDP" and the specific port number(s).
    • Under "Action," select "Allow the connection."
    • Under "Profile," ensure it applies to "Domain," "Private," and "Public" networks.
    • Under "Name," give it a descriptive name (e.g., "Allow RDP from My_Home_IP").
  5. Advanced Scoping: As mentioned, use the "Scope" tab when creating a rule to limit source IP addresses. For example, for RDP, set "Remote IP addresses" to "These IP addresses" and add your public IP.
  6. Outbound Rules (Less Common for Initial Setup): Typically, default outbound rules are fine, allowing your server to connect to the internet for updates or external services. However, in high-security environments, you might restrict outbound traffic too.
  7. Regular Review: Periodically review your firewall rules. If you've decommissioned an application, close its ports. Unnecessary open ports are security risks.

By diligently configuring your Windows Defender Firewall, you're adding a critical layer of defense to your Hetzner Windows server setup, protecting it from many common internet threats. This proactive approach ensures your server remains secure and serves its purpose effectively.

Common Pitfalls and Troubleshooting Tips

Even with the best guides, embarking on a Hetzner Windows server setup can sometimes throw a curveball or two. Don't worry, guys, it happens to the best of us! The key is to know some common pitfalls and have a few troubleshooting tricks up your sleeve. Being prepared for these little snags means you can quickly get back on track and avoid unnecessary frustration. After all, the goal is a smooth and successful Windows server setup. One of the absolute most common issues folks run into is related to network connectivity after installation. You've installed Windows, you're connected via KVM, everything looks fine, but you just can't RDP in, or your server can't reach the internet. This usually points to a few culprits. First, double-check your firewall configuration. Did you enable RDP in Windows Firewall? If you changed the RDP port, did you allow the new port? Also, ensure that the network adapter drivers are correctly installed. If you see "No Internet Access" or similar warnings on your server, head into Device Manager and make sure there are no yellow exclamation marks next to your network adapter. Sometimes, a simple reboot after installing drivers can resolve this. Another often overlooked aspect is the network configuration itself within Windows. Hetzner servers are typically configured with static IP addresses. While Windows usually picks up DHCP settings, it's wise to verify your network adapter's IPv4 settings – ensure it's set to "Obtain an IP address automatically" unless Hetzner specifically instructed you otherwise to set a static IP (which is rare for their standard setup). If all else fails, the Hetzner Robot panel's "Network" tab can provide invaluable information, including your server's correct IP address, gateway, and DNS servers. If the network isn't coming online, you might need to manually configure the network adapter settings within Windows to match what Hetzner expects.

Another frequent headache during a Hetzner Windows server setup relates to RDP access problems. Even if the network seems fine, you might still struggle to connect via RDP. Beyond firewall issues, this could be due to incorrect RDP settings on the server itself. Make sure Remote Desktop is actually enabled (Server Manager -> Local Server -> Remote Desktop). Also, verify which users are allowed to connect via RDP. By default, members of the "Administrators" group can connect, but if you created a separate user, you might need to add them to the "Remote Desktop Users" group. Strong passwords are great for security, but make sure you're typing them correctly! It sounds obvious, but a typo can be maddening. If you suspect an RDP service issue, you can check the "Services" snap-in (services.msc) and ensure the "Remote Desktop Services" is running and set to automatic startup. Furthermore, if you've been messing with Group Policy, some policies might unintentionally block RDP access. If you're really stuck, a quick reset of Group Policy to defaults (though proceed with caution if you've made other custom configurations) or checking for specific RDP-related policies might help.

Performance issues can also crop up. If your Hetzner Windows server feels sluggish right after installation, it's often due to pending Windows updates or missing drivers. As we discussed, give it time to fully update and reboot as needed. Resource-hungry background services or applications that start automatically can also hog CPU and RAM. Use Task Manager to identify any culprits. If your disk performance seems slow, ensure you've got SSDs (preferably NVMe) and that your storage drivers are up to date. Sometimes, it's simply a matter of the server doing background indexing or telemetry. Always check the system logs in Event Viewer for any critical errors or warnings that might shed light on a deeper problem. Remember, the Hetzner Robot panel is your lifeline. If you truly get stuck and can't even get RDP to work, you can always use the KVM console to get back in and troubleshoot directly, or even use the rescue system to access your drives and fix configuration files if necessary. Don't be afraid to reach out to Hetzner support if you've exhausted all your options; they're there to help with hardware and basic network issues. Having a solid understanding of these common troubleshooting steps will save you a ton of time and stress, ensuring your Hetzner Windows server setup remains robust and reliable.
