How to prevent Windows 7 Remote Desktop time outs?

I need to modify your statement.. I had the same issue on a PC in my facility, and the path was: "Security settings > Local Policies > Security Options > Microsoft Network Server: Amount of idle time required before suspending session".

I had to hunt for a bit, using your reference. Though very good information, was not 100%. This should correct it.

Push Start > then type "Local Security Policy"

Inside the Local Secuirty Policy Snap in

Security settings > Security Options > Microsoft Network Server: Amount of idle time required before suspending session

Default is 15 minutes.
