System: an XP PC and a PC recently upgraded from XP to Windows 7. I had no problem connecting the two (went kind of automagically, to be honest), and also could share folders both ways.
This morning, however, the Win7 PC no longer sees the XP machine, and while the XP PC still shows the other one in its workgroup it can no longer access it. I didn't change any networking settings(!). Both PCs are still member of the same workgroup.
Question: how can I set up communication between an XP and Win7 PC?
Seems I was a bit too quick with my reboot comment. The connection was lost again, and this time didn't restore upon rebooting. I can ping the other computer, though. Annoying! Any help will be greatly appreciated with upvotes and possibly accepting answer :-)
