I have a small home network 2 windows 7 PCs and an XP PC When I try to link to the network the XP asks for the group name and win 7 doesn't use a group name. I can get to the Internet with out a problem but can't share the printer that is connected to the router or files on the other PCs. How do I fix it so I can share the printer and files? 1 person got this answerI do too
