I have two computers. I'll call them "mine" and "his".
"mine" has both Vista and Windows 7 installed (dual boot), "his" has XP Home.
When I boot "mine" into Vista, the networking works perfectly. Vista and XP can see files and printers and all is great.
When I boot "mine" into Windows 7, I can see "his" computer and access his files and his printer. However "his" computer doesn't even see "mine" show up in My Network Places.
I've checked the workgroup in Windows 7 and it's the correct name.
I've gone to the Network and Sharing Center in Win 7 and set my Network to "Home network".
I played briefly with the "HomeGroup" thing in Win 7 until I reached the point where it said it only worked for computers running Win 7. However it does says HomeGroup: Joined (and it appears that I've joined a HomeGroup).
So now what? Why can't XP see the Windows 7 computer?
