Forefront TMG 2010 RDP suddenly not working anymore

November 24, 2010 6 comments

A weird thing happenend today with our TMG 2010 box. We powered down our server to add some extra memory to get some better performance. After powering on we could not RDP into the server anymore. After we logged on to the console we did a netstat -ano | findstr “3389” but it show no results. The firewall log shows:

Closed Connection TMG-FE 23-11-2010 17:48:44
Log type: Firewall service
Status: A connection was abortively closed after one of the peers sent an RST packet.(0x80074e21 FWX_E_ABORTIVE_SHUTDOWN)
Rule: [System] Allow remote management from selected computers using Terminal Server
Source: Internal (
Destination: Local Host (
Protocol: RDP (Terminal Services)
Additional information
Number of bytes sent: 52 Number of bytes received: 40
Processing time: 0ms Original Client IP:

After playing around we found a fix:

start an MMC and add the RD session host configuration snap-in.
goto the connection section and look at the properties of the RDP-tcp protocol
goto the adapter tab..
enter listening on all adapters and close
click on disable connection
click on enable connection
goto the adapter tab
enter listening on internal interface
click on disable connection
click on enable connection

enter in a dos box
netstat -ano | findstr “3389”

now its listening again and we could RDP again….weird fix but it works for me.
