Tonight I’ve had a problem connecting to a server I built earlier today but as I left I forgot to enable the Remote desktop connection. AHHH i hear you say.
No problem I remember reading several years that it was just a reg key to change turn it on or off, and fortunately its the same on Server 2008.
Simple change the fDenyTSConnections (REG_DWORD) from 1 to 0.
1 = turn off
0 – turn on
Simple reboot the server with "shutdown -m \\servername -r
Hope this helps
