I am running Windows XP Pro at work on a network and only my PC will lose it's connection to the network at almost the same time each day around 5pm (guess it's telling me to go home). The internet works, but I lose the network. I have to either reboot or chose log out and log back in. A huge time-waster.
The only scheduled task is a backup that starts at about 11pm. The server has no restrictions on a time frame.
What can I check to resolve this issue? It's been going on for months.
