Set Terminal Service session Timeouts/Limits (Windows)

From ben.goodacre.name/tech

I order to prevent all your terminal service sessions being used and thereby blocking access to a server, tsadmin can be used to log users off remotely or session timeouts / limits can be imposed.

Add the following Registry entries, creating a 1 hour disconnected session limit and a 2 hour idle session limit:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp]
"MaxDisconnectionTime"=dword:0036ee80
"MaxIdleTime"=dword:006ddd00

To add the entries save as whatever.reg and double-click.
