RDP via TS Web “error occurred… Desktop Gateway server.”

Problem connecting to server via RDP when using the TS web interface.

  1. Login OK to the TS Web Interface.
  2. Click “Connect” to server
  3. RDP Loads…
  4. Error displays: “An error occurred while sending data to the Remote Desktop Gateway server. The server is temporarily unavailable or a network connection is down. Try again later, or contact your network administrator for assistance.”

Note: This problem is related to newer features in RDP v7 which are not installed by default on Windows XP Service Pack 3 (SP3), Windows Vista Service Pack 1 (SP1), and Windows Vista Service Pack 2 (SP2)
