XP Pro PC Not Accessible Within Workgroup

[Ben Scaithe]

I am having a recent issue accessing a Windows XP Professional PC. It is in
a workgroup with two other PCs (both XP Pro). At some point earlier this
year, it lost the ability to be accessed by the other two. Neither of the
other two can access its file shares, nor can they ping it (with or without
firewalls). The broken PC can browse the Internet and can ping the other
two, but cannot ping its own IP address (localhost works, though). The
broken PC cannot access the other PCs via NetBIOS names, but CAN if I put in
their IP addresses instead (i.e. \\192.168.1.100). The broken PC also
cannot browse the workgroup - says the usual "Workgroup is not accessible".
I have tried the following:

Reran Network Setup Wizard
Set a static IP address as opposed to dynamic from DHCP
Disabled every unnecessary service and startup app
Tested network access in Safe Mode w/ Networking
Turned on and off the Computer Browser service
Right clicked on Local Area Connection and ran a Repair
Changed the NetBIOS setting from Default to Enabled
Uninstalled the network card in Device Manager and reinstalled
Reset TCP/IP via - netsh int ip reset c:\resetlog.txt

None of these have made any progress.

Any other ideas, or is it looking like time to wipe and reload?

Ben,

I'd look at LSP / Winsock corruption.

And I'd look twice for overlooked personal firewalls.
