Add Session Host to Deployment

Hi guys,

strange issues here. I can't add a Session Host to an existing Deployment.
It's all Windows Server 2012 R2.

If I try to add the Session Host via PowerShell (my preferred way), I get this error:

New-RDSessionCollection : The RD Session Host server WIN-DJQ9B0G1C3M.fqdn.com does not exist in this
deployment.
At C:\Windows\temp\schtask6.ps1:8 char:1+ New-RDSessionCollection -CollectionName 'Planning' -CollectionDescrip ...+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~+ CategoryInfo          : NotSpecified: (:) [Write-Error], WriteErrorException+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,New-RDSessionCollection

If I try to just add the server as a new Session Host via the UI, I get this error here.

I now tried it via GPO and on the Session Host I'm getting the following error in Eventlog:

Remote Desktop Services failed to join the Connection Broker on server WIN-1A1B9M6OF6H.fqdn.com.
Error: Current async message was dropped by async dispatcher, because there is a new message which will override the current one.

I manually added the Session Host to the "RDS Endpoint Servers" group as that was missing. This didn't resolve any issues.

Thanks,
David
