network confusion

I am experiencing a weird network problem. I have a Windows XP desktop, and Windows 7 laptop and a Ubuntu laptop. All are on the same named Network which is called HOME All machines are on yet the 2 windows machines don't see each other, but I can see both windows machines shares from my linux laptop. The strange thing is, I have mapped one of the XP drives to the Windows 7 laptop and it saw it for about 2 days and now it doesn't. I checked that every computer is connected to the HOME network. What next? More importantly, why does this occur?

yes, i have tried that, still experiencing the problem, Now the XP machine is not showing in my network group at all from my Win7 laptop. Still searching this board and others, plus google. Thanks for the reply

If your network contains computers running different versions Windows, put all computers in the same workgroup. Here is a resource to help you set it up: http://windows.microsoft.com/en-US/w...ons-of-Windows.

I have them all on the same network (workgroup) it is named HOME.
right now after rebooting the windows machine, they are all showing now. Time will tell, I am monitoring everything closely to see if I detect why one or two computers drop out.
Thanks.
