Our scenario is 3 offices. 1 VPN concentrator 3005, and 2 VPN clients 3002. Only 2 of the workstaions on the client sides can see everyone else on the other remote locations. The other workstations are limited to just seeing the same 2 workstations on the concentrator side. All workstations are the same WinXP SP2. All network settings are the same. "IF" I take one of the individual workstations that is having a problem and GO AROUND the client and use Microsofts PPTP VPN all is well. And accessing from anywhere using PPTP is fine, no problem. This seems soooo bizarre, please help me if you can. OHH another thing, this setup worked fine before we swapped the concentrator and one of the clients from thier locations.
I have this problem too.
