I use mstsc to connect from my laptop back to my office desktop. A recent
change in our desktop image is now causing the desktop session to terminate
all processes left running 15 minutes after I disconnect. My intent is to
keep those processes running so I can reconnect to them later. This worked
until the recent change in our standard windows image.

Our windows install folks tell me there is a registry change in
HKLM\System\CurrentControlSet\Control\Terminal
Server\DefaultUserConfiguration that will fix this, but they can't say just
exactly what the change should be. So far I haven't been able to find the
right change to make.

Any pointers to how to keep this idle disconnect from occuring will be
greatly appreciated.
