Windows 7 to XP Networking Issues

[pzzs7f]

Trying to network my XP desktop and Windows 7 desktop. The Windows 7 machine is connected by wire to a 2-wire wired/wireless router. The XP machine is connected via wireless D-Link DLW-G510 to same router. I have internet connection from both devices with no problem...but cannot get either to see each other from the other. Using the 2-Wire interface I can see both devices on the network thru the 2-wire router. But I cannot see either machine from the other via network in windows.

I have win7 machine set to Work network, sharing and discovery enabled, and passwords required turned off. On the XP machine I used Network Setup Wizard to setup the network on that end. On both ends the workgroup s named "WORKGROUP" and the machines have unique computer names...Windows 7 is USS-Excalibur, XP is USS-Excelsior.

Yet neither sees each other. In addition, I have a work laptop running Vista connected to my corporate work network via the same 2-wire router (wired). And I can see that laptop device from the win7 machine when I show the network map, but not the XP machine.

I am totally confused on where the problem may be...Can anyone help??

This usually has to do with sharing permissions in XP.

Try this.

What I did was to disable the firewall on the XP Machine -- just for testing
reset all the file / print sharing options
then on the XP machine run the NETWORK SETUP WIZARD from the control panel -- not sure what this actually does BTW but at this stage I was going to try anything. I ensured the workgroup name was the same as the W7 / Vista computers. Also when this completes check Finish the wizard - don't run on other computers.

Re-boot the XP machine.

Hey presto. Open Sesame.

OK per your recommendation I diabled firewalls completely. That solved it on the XP side...I can now see and access files on the Win7 machine from the XP machine. But on the Win7 side I still can't see the XP machine. Attached is the map that gets displayed...as you can see the XP box shows up a question mark and is not selectable. The jmckinney1 box is the laptop (not worried about accessing it).

What am I missing??

Thanks.
