Sounds to me like the VPN client is timing out after a period of inactivity.  What is the network setup you're using from your PC to the Win2k server?

Do you have access to the work NAT server?  If so, check the timeout settings on it.  On ours (Cisco PIX 515), if there is no activity for 1800 seconds (30 minutes), it will disconnect.  I think this is a pretty standard feature.  If it is the case, I would not mess with it too much, because you don't want a lot of old VPN connections just hanging out there if they're not being used and didn't disconnect properly.

What about things like power management on the home PC?  Could it be that your PC is "going to sleep" and shutting down your network connection?

Your ISP maybe resetting  its connections overnight, normally this would be transparent but the VPN is slightly more sensitive to packet dropouts and the tunnel that makes the VPN drops out of sync and needs reinitiating.

How are you setting up your vpn?  If you are doing it with hardware you may be able to set a "keep alive" which will keep your system up.
