System worked fine for nearly 1 year. Experienced series of disk controller errors on partition D of hard disk, chkdsk ran on next boot, after which network connection shows limited or no connectivity. (Op system is on C partition) Coincidence? Also have gotten error message from Windows twice during numerous boots over past few days of troubleshooting. "Windows is unable to determine the license status of this machine" or words to that effect. When this happens, screen says logging off for several seconds, then proceeds to finish booting!
Machine is Gateway Athlon 1200, WinXP Pro, with 3COM 10 MB ethernet card. Network status showed it receiving packets but not sending any. Tried removing and reinstalling card drivers, no help. Tried new network card, no help. back to original 3 com card. Deleted and re-installed network components (except Eacflt driver, which wouldn't delete because it was in use) Have now managed to break it completely - won't send OR recieve packets. Repair tool says it can't renew IP address.
Replaced HD temporarily with older one containing older version of Win XP - network connection works fine. Did look through forum threads, tried some of posted checklist items with no luck. I'm stumped.
