The quickest way to resolve this issue is to change the registry key that enables Remote Desktop directly. I usually have remote registry access to the system because I am an administrator on the system.
- Open up Regedit
- Connect Network Registry
- Select the computer you want to change the setting on (other server will need to be in the domain)
- On the network computer, browse to HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server
- Change the fDenyTSConnections to 0
You might need to reboot the computer – I am usually able to get this to work without rebooting.
To remotely reboot a computer type the following
Shutdown –m \\<servername> -r
