Dave,

I don't have the solution, but check the following points, which
could perhaps cause this problem.

* Make sure you have only one transport protocol installed,
namely TCP/IP. Remove, disable, or at least unbind other
transport protocols like IPX (NWLink) and NetBEUI.

* If you had other networking clients installed, like certain
Netware clients, you may be in for a long, bumpy ride. Some do
damage that is almost impossible to repair. You may want to try
a repair installation of Windows XP, followed by applying
Service Pack 2 again, or, better, a repair installation with a
slipstream version of Windows XP with Service Pack 2 already
integrated.

* Repair the IP stack with the Repair command or, better, with
the command: netsh int ip reset

* If the loopback feature is enabled in a connected router,
disable it. You may even need a firmware upgrade.

* Change the workgroup name in all computers to a new, simple,
short, perhaps even all upper case one, to make sure there
aren't any problems there. You can later change it back.

* Check whether NetBIOS over TCP/IP is enabled. It should be.

* Check all NetBIOS names for possible duplicates. For example,
if the workgroup name coincides with a user or computer name,
this could cause the problem. Try opening a command line window
and issuing the command: net view

* Then issue the command: net view \\computername, where
computername should be replaced with one of the names displayed
with the simple net view command. Check all names for possible
duplication.

* Check your router's diagnostic and information pages for NAT
information, like which computer has which IP address. Any
duplication here could point to the problem.

* Disable, better uninstall or upgrade, all antivirus software
and third party firewalls.

* Rid the computer of adware and spyware. For example, run
Spybot Search & Destroy.

And, most importantly, if you find (or anyone finds) that one of
these points or any other procedure solved your problem, please
reply here or post a new message to let us all know.
