Set Terminal Service session Timeouts/Limits (Windows)
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.
