I have two Windows 2012 servers configured with remote desktop services. They are seemingly identical (as far as I can see) both reasonably fresh installs.
On Server A, I can access rdp from Windows 7 clients and from Windows XP clients (also from Windows 2012 and windows 2003 servers).
On Server B I can only RDP from Windows 7 clients NOT from Windows XP (or Windows 2003). The error varies slightly depending on the client , but is either "Because of a security error, the client could not connect to the remote computer. Verify that you are logged on to the network, and then try connecting again" or from the latest rdp client you get "The remote session was disconnected because the remote computer received an invalid licensing message from this computer"
The servers are both 'almost' identical, but something is obviously different between the two but I cannot work out what.
The environment is a domain.
The servers are both configured independently to each other with their own licencing , RD Gateway, RD connection broker and RD session Host. I cant see anything in the settings for any of these elements that differs between servers.
Any ideas?
Many thanks
Paul
