I have 2 xp pro sp1 and 1 xp home sp1 connected to linksys befsr41 ver3 router with roadrunner cable. One of the xp pro units (lets call it unit "A") recently developed problem connecting to internet. Specifically, if it connects at all, need to refresh a lot and the other 2 computers lose their connectivity. I did the usuals, reset modems, winsock rebuilds, sfc.exe, ipconfig /flushdns, changed NIC, etc. to no avail. I substituted the router with same results. Swapped out unit "A" with another computer and had no problems. Problem does not show up if unit "A" boots in safe mode w/networking. No recent software/hardware updates or changes. Hijack This log is clean. Looking for any ideas to narrow this down.
