Hello Florian Stemich,
Thank you for posting in Microsoft Community forum.
The activation error 0x80072F8F in Windows Server 2022 typically indicates a problem with the system's date, time, or time zone settings, or it might be related to SSL/TLS issues during the activation process. Here are some steps you can take to troubleshoot and resolve the issue:
- Check Date and Time Settings:
Ensure that your server's date, time, and time zone settings are correct. Misconfigured time settings can prevent activation.
Right-click on the time display in the taskbar, select "Adjust date/time," and make sure the settings are accurate.
- Synchronize Time with an Internet Time Server:
Open a Command Prompt with administrative privileges and run: w32tm /resync
- Check Your Internet Connection:
Make sure your server has a stable internet connection. Intermittent or unreliable connections can cause activation issues.
- Check for SSL/TLS Settings:
Ensure that your server is capable of connecting to Microsoft's activation servers using secure SSL/TLS protocols. Check that TLS 1.2 is enabled, as older versions might be outdated or disabled.
You can enable TLS 1.2 through the registry editor or by using Group Policy.
- Windows Update:
Make sure your server has the latest updates installed. Sometimes, missing updates can cause activation problems.
6.Firewall and Proxy Settings:
Ensure that your firewall or proxy settings are not blocking access to the Microsoft activation servers. You may need to allow specific URLs or ports related to Microsoft's activation services.
- Run the Activation Troubleshooter:
Go to Settings > Update & Security > Activation and run the activation troubleshooter.
- Use Command Prompt to Activation:
You can also try activating your server via the Command Prompt. Open a Command Prompt with administrative privileges and type:
slmgr.vbs /ipk <your_product_key>
slmgr.vbs /ato
Note: Replace <your_product_key> with your actual product key.
I hope the information above is helpful.
If you have any question or concern, please feel free to let us know.
Best Regards,
