I have an HP Pavillion a1547c running XP Pro SP3. Customer complained of no internet a few days after he got it back from me, all I did initially was backup QuickBooks company file. Internet worked. He said, "nothing happened, nobody messed with anything."
My troubleshooting steps I've taken with no success.
Ruled out any virus infections
Attempted to release/renew IP - IPCONFIG command not allowed
reset tcp/ip stack
ip and DNS both set to obtain automatically
updated NIC driver
used old USB to Ethernet adapter - showed connected but no packet activity
disabled onboard LAN and installed NEW NIC with same results
Firewall will not start
No active a/v product installed
connections set to automatic on Internet Options
Same results in safe mode w/ networking
