Win 7 Network browser not seeing XP systems

I'm having a lot of fun with Windows 7 RC1, but one problem I can't seem to fix. If I try to browse to my XP systems all I see isf this one, the Windows 7 system. I can net view all shares on \\Desktop and \\Webserver, both of which run XP Pro. I can start Windows Explorer using UNC names like \\Desktop\\HP_C (C: drive on HP Desktop), and once I've done that, I can then see all the shares for \\Desktop in the same Windows Explorer window. Seems to be just the network browser that is not working yet all the necessary services (I think) are running. I am not using Home Group, just straight sharing. Any ideas greatly appreciated.

Thank you Jessica. I'll see what I can find and post my problem if needed.

Only got a single response on the Win 7 forum, but … I was working on my daughters new computer today and couldn't get Network browsing to work there, then I remembered to check the workgroup name and they were different. Made them the same and browsing worked. Came home and checked my Win 7 setup and the workgroup name was different than the XP computers. Made it the same and Network browsing works fine now.
