I had a similar problem caused by one of the system admins setting a 1 hour lease on ip addresses for one of our machines. When the hour expired, it was kicked off the network.
Rebooting fixed it because then the machine grabbed another ip address and was good for another hour.
...why he did it, he never explained...lol.
Its a longshot but to check, type start, run, winipcfg, click more info, select the network adapter and look at the bottom to see when your lease expires.
