Recently I have RDS installed on Windows 2008 R2 server. Only local admin user able to RDP without any issue. This is not the case for domain users (even they are part of the RDP users group). I had confirmed the same the Allow log-on option in group policy has allowed RDP users), as well as network service account running the RDS service. Just few queries:
1. Server has pointed to the licensing server but having issue contacting the server (I assume this should not contribute to access denied issue to the domain users).
2. If users RDP using mstsc /admin switch (via console mode), it looks like users able to rdp with no issues.
Any idea why this may happened? Thanks.
