Run the Network Setup Wizard on the computer that can't be accessed.
That's often all that's needed to fix the problem. Tell the Wizard
that the computer connects to the Internet through a residential
gateway (router).

If that doesn't solve the problem, try these tips:

1. 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

2. 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

3. Run "ipconfig /all" on each computer 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:
