Run XP's Network Setup Wizard on CC, and tell it that the computer
connects to the Internet through a residential gateway (router).
That's often all that's needed.
If that doesn't solve the problem, these tips should help:
1. If the computers run the original or SP1 versions of Windows XP,
disable XP's built-in Internet Connection Firewall on local area
network connections -- it's for use only on a direct modem connection
to the Internet. If they run SP2, enable the exception for file and
printer sharing in the Windows Firewall. Disable and un-install all
other firewall programs while troubleshooting. When un-installing a
firewall program, use the un-install procedure provided by the
manufacturer . Don't use Control Panel | Add or Remove Programs,
which might not completely un-install it.
For more information, see:
Windows XP Internet Connection Firewall
http://www.practicallynetworked.com/sharing/xp/ic_firewall.htm
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 all computers.
Details here:
Enable NetBIOS Over TCP/IP (NetBT)
http://www.practicallynetworked.com/sharing/troubleshoot/netbt.htm
4. Run "ipconfig /all" on XP 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:
