Hello. I have a client with a Windows 2008 R2 RDS License server in a domain, while the RDS application servers are in a workgroup. The client claims that the Windows 2003 Terminal Servers can access the license server just fine, but the Windows 2008 servers cannot contact the license server.
An error is returned: "RD Licensing Manager could not connect to the license server. Check the following: 1. The Remote Desktop Licensing service is started on the license server. 2. Your credentials have sufficient privileges on the license server."
It does not seem likely that this would work, since according to https://support.microsoft.com/en-us/kb/2473823,the servers either need to both be in the same workgroup, or the same domain, or in two different domains with a two way trust.
Is there a way to get Windows 2008 R2 RDS servers in a workgroup to accept licenses from an RDS license server on a domain? Why would this work for Windows 2003 servers in a workgroup? Could there be another issue altogether, like, what ports need to be opened between the servers?
I appreciate any help you can provide on this topic.
Thank you,
John
