These tips should help you get everything working:
1. Make sure that a firewall isn't blocking access:
1a. Permanently disable the XP HE SP1 Internet Connection Firewall on
the LAN connection.
1b. If the XP HE SP2 Windows Firewall is enabled, make sure that the
exception for File and Printer Sharing is turned on.
1c. If you've installed a third-party firewall program, configure it
to allow access by other computers on the LAN. Disable XP's built-in
firewalls if you've installed a third-part firewall.
2. Use only one protocol for File and Printer Sharing. If the network
needs more than one protocol, unbind File and Printer Sharing from all
but one of them. Details here:
Windows XP Network Protocols
http://www.practicallynetworked.com/sharing/xp/network_protocols.htm
3. Make sure that NetBIOS over TCP/IP is enabled on both computers.
Details here:
Enable NetBIOS Over TCP/IP (NetBT)
http://www.practicallynetworked.com/sharing/troubleshoot/netbt.htm
4. Run "ipconfig /all" on both 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".
For details, see these Microsoft Knowledge Base articles:
