Hi lsavidge,

1. Determine the IP address and subnet mask of both computers (cmd-shell: ipconfig).
   => make sure they are not identical but differ only insofar as the subnet masks allow
   => They should start with
   => Note the IP addresses
2. Try and ping the PCs from the respective other PC.
   => they should repsond within some delay time (not timeout)
3. go to 'My Computer' -> Properties -> Computer Name (tab) and check that the both belong to the same WORKGROUP
    Note the computer names

4. Try and search the computers by name (network->search computers) from the respective other computer.
5. Get back to us with the results ;-)

you obviously have connectivity happening so look at security.....

check the windows firewall service or any others and make sure they are disabled completely for starters....

what version of xp are we dealing with? pro or home?

Have you got any weird products such as Norton/Symantec/McAfee installed on the PC?

I was not able to use any of your tips as I had to reset the machine to factory settings.

I had this problem, its a simple fix.

Do the following and see if it doesnt fix it.

Start - Control Panel - Network and Internet Connections - Network Connections - Right Click on "Local Area Connection" or whichever your default connection is. - Properties - TCP/IP - Install - Protocol - Add - Install all three protocols listed there. Do this on all the systems in the workgroup. This fixed my problem before where I couldnt see the other Workgroup PC's, especially ones that were on a wireless connection.

I found an answer to my own question.  Please close my question.  The answer is to enter in the IP address of each computer into your firewalls ' permission area.  Each computer must get the other's IP address and then both of them will show up on the screen hopefully this is helpful to you and to others.

I just gave the points to Jay Jay because when the problem occurred again after a did the reinstall I checked my firewall to see if the computers had permission to see each other they didn't.  So I entered in their respective IP addresses into the firewall permissions area of the program and they both popped right up, problem solved and I didn't have any more trouble. Jay Jay pointed me in the right direction and I learned how to fix the problem myself.
