Some months ago, we had to move our servers from Germany to North Europe and recently Windows is asking us to provide a valid product key. Running the command slmgr.vbs /dlv we could see that the registered KMS machine name was "". Apparently, for North Europe (at least) the server name must be ""

To change the licensing server, we have to run the following line in a elevated porwshell console:
iex “$env:windir\system32\cscript.exe $env:windir\system32\slmgr.vbs /skms”

Now we only have to wait a few minute and request a new license with the command slmgr.vbs /ato

That's it, as simple as that. Now our servers have a valid license again.

P.S. We are not sure if the cause of the issue is the change of datacentre, but for sure, using the right license server fixed the issue.
