Thanks for the report. I should have asked you to make one more test:

   \\IP-address

When computer access by IP address succeeds but computer access by
name fails, it indicates a problem with NetBIOS name resolution.
These tips should help fix the problem:

1. Make sure that NetBIOS over TCP/IP is enabled on all computers, as
shown here:

Enable NetBIOS Over TCP/IP (NetBT)
http://www.practicallynetworked.com/sharing/troubleshoot/netbt.htm

4. Run "ipconfig /all" on the XP computers and look at the "Node Type"
at the beginning of the output. If it says "Peer-to-Peer" (which
should actually be "Point-to-Point") that's the problem. It means
that the computer only uses a WINS server, which isn't available on a
peer-to-peer network, for NetBIOS name resolution.

If that's the case, run the registry editor, open this key:

   HLM\System\CurrentControlSet\Services\Netbt\Parameters

and delete these values if they're present:

   NodeType
   DhcpNodeType

Reboot, then try network access again.

If that doesn't fix it, open that registry key again, create a DWORD
value called "NodeType", and set it to 1 for "Broadcast" or 4 for
"Mixed".
