Network Connection Timeout

Archived from groups: microsoft.public.windowsxp.help_and_support (More info?)

I have noticed that many of the newer machines that we buy with XPPro
preinstalled, have network connection timeouts set such that they will
disconnect from the network overnight, requiring a reboot, or at least a log
off. I had asked about this some time ago, and was directed to a website
providing registry tweak information to resolve this problem.
Unfortunately, I seem to have lost my information, and connect remember the
tweak.

Can someone point me in the right direction?
