Remotely enable terminal Services for Remote Desktop

Here's one of those registry keys I can never remember when I need it every couple of months or so. You've logged into the client's server or you're on their network directly but want to take over a PC to fix some pesky Outlook problem.

So you've got access to Manage their Computer or load their registry with Regedit.

HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server
 fDenyTSConnections=0  (REG_DWORD)

and reboot.

If you want screenshots of the details take a look at the omniscient Daniel Petri's website here.
