We had an issue recently trying to RDP to our newly created TMG server. We had allowed the machine we were using to connect to the server in the TMG’s Server System policy.

When running logging in TMG we could see the RDP server hitting the server but then immediately getting a closed connection with the following message “A connection was abortively closed after one of the peers sent an RST packet

Resolution

1.  First Log onto your TMG Server

2. Right-click the highlighted icon and choose “Open Network and Sharing Center”

After this all worked again even after a reboot Smile
