I have a Windows XP SP3 (current patching and trend micro current and scans clean) user who keeps losing his connection to the file server, but he does not loose connection to the internet. This happens at random times but mostly during the night while the pc is on but logged off. All the hardware has been switched (Network card, patch cable, wall outlet and switch.
