Me and my friend are trying to connect 3 computers together: 2 using XP and one Windows 7. We have successfully connected the XP computer that is connected to the router directly with cable and the Windows 7 computer but the other Windows XP computer doesn't show in any workgroup that we've created. What might be the problem?

What versions of XP you're using? Both are XP professional? –  Naveed Ahmad Apr 22 '11 at 11:05

Ensure the workstation and browser services are started on the XP machine that is not appearing.

Check that the firewall on the 2nd XP machine is configured to let local network traffic through in both directions.

  • In XP's Firewall (firewall.cpl) enable the "File and Printer Sharing" exception;

    (if you use a third-party firewall, allow TCP 139, TCP 445, UDP 137, UDP 138 and ICMP Echo)

  • Use Wireshark to watch for browsing traffic (display filter smb || nbss || nbns || netbios || browser)

  • In 7, try nbtstat -a <HOSTNAME> and nbtstat -A <IPADDRESS> (where <HOSTNAME> and <IPADDRESS> are the XP computer's name and IP address respectively); also check if they return the correct workgroup name.

  • Try restaring the "Computer Browser" service in all computers

File and printer sharing is enabled nbtstat says that the host cannot be found (tried with IP adress also) restarted the computer browser service and it didn't have effect –  Martin Apr 22 '11 at 12:05
