Summary:
- Problem using Remote Apps & RDP from "RDWeb" interface when accessed from the public internet.
Background:
- Currently have, 1 x Windows Server 2008 TS Web Access & 1 x Windows Server 2008 R2 RD Web Access setup.
- Both are configured to use remote apps inc RDP.
- Both allow login to the web interfaces (Prompts for login when connection to URL).
- Both allow RDP connections internally and work correctly without problems.
- Both have Digicert SSLs installed, tested as valid.
- These are standalone installations and not in a Farm.
Issue:
TSWeb (Server 2008) works correctly and allows RDP connection to itself from the "Remote Apps"
RDWeb (Server 2008 R2) does not and the RDP connection errors:
"Your computer can't connect to the remote computer because the Remote Desktop Gateway server is temporarily unavailable. Try reconnecting later or contact your network administrator for assistance"
I am trying to connection to the RDWeb server externally from a Windows 7 PC (RDP 6.2.9200). If I click the "Remote Desktop" selection on the TS Web Interface, I can also RDP to other Windows Server 2003 terminal servers, however any other Server 2008 R2 servers to not work.
Questions:
- Is there something being missed in the configuration?
- Are there any fundimental differences between Server 2008 TS Web and Server 2008 R2 RDWeb? (Security etc?)
- Would someone also be able to clarify the need to open port 3389 on the firewall, my understanding was that RDP (3389) should be wrapped in the HTTPS (443) traffic therefore only 443 would need to be opened. Unfortunately we have had to allow 3389 on the firewall for RDP connections to function from the outside work and get TSWeb working correctly. I presume I have misconfiguration reading this post: http://social.technet.microsoft.com/Forums/en-US/winserverTS/thread/d5906eb8-9a08-42b0-bdd8-356383401554
