I have a very strange, and puzzling issue with the RDC 6.3 client. I have two different Windows 8.1 PC's that are unable to complete their login to either a Server 2008 R2 or Server 2012 R2 RDG environment. They initiate the connection from the RDWeb
host (which is the same as the RDG and RD Connection Broker), they sit there at "Initiating remove connection..." If I use the 6.2 client that's present on Windows 8 or even Windows 7, no issues.
I have two pairs of Remote Desktop Session Hosts behind two different RDG's, each with the same OS version. I have no licensing issues, as I have plenty of TSCals. What can I do to troubleshoot this?!?!?
