I needed to RDP into my desktop at work to complete a couple of tasks while at home but didn’t have RDP enabled on it. I connected to our VPN and RDP’d into one of the servers. I then connected to my desktops registry via regedit’s “Connect Network Registry” feature.
The key I needed, fDenyTSConnection, was in HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server.
I changed the REG_DWORD value from 1 (Remote Desktop disabled) to 0 (Remote Desktop enabled), then remotely rebooted my PC, shutdown -m \\%PCNAME% -r.
After the reboot I was able to log in via the domain admin account. Once logged in I added my domain account to the users allowed to utilize remote desktop.
