Have a laptop that can access Internet but NO LONGER can join workgroup. When I click "view workgroup computers", comes back with my workgroup "not accessible, check with admin on permissions". But it does have internet access. It has stopped working in last month and can't figure it out.
Home network has four PCs: 1) WIndows 2000 prof 2) XP home w/ problem 3) XP home w/o problem 4) XP prof on laptop also used at work. This is a wireless network around a router connected to cable modem. The system with Win 2K is set-up for file / print sharing. I've no problem with #4 XP prof laptop accessing internet, seeing the workgroup (including the problem XP system), printing via the Win2K system, etc. #3 can access the workgroup and the internet. Just #2 has problems.
Two other clues. I can ping from #2 to #1 but not #1 to #2. Also, the only thing I can think of in timing was that I changed from an Win2K work laptop to #4 roughly when the problem showed up ... although not clear cause / effect.
