RDS - New users immediately logsoff after log on

I am running Windows 2008 R2 server with Remote Desktop Services. New users are immediately logsoff after connecting to the server.
When I exclude the new created user from the GPO's the session will logon.

If the problem occures event id 1542 - Microsoft-Windows-User Profiles Service is created. Any ideas?
