I've setup a vpn on a windows 2003 server and can connect successfully from an external win2000 or win7 machine. On both machines I'm unable to browse the network and I have problems connecting to one other server on the network (server A). Both machines can ping server A and server A can ping both machines.
The win2000 machine is able to remote desktop to server A however when trying to browse it's folder it asks for a username/password. It will not accept a u/p of an account on the domain, however I created a local account on server A and this works.
The win7 machine cannot remote desktop to server A and gets the error: "You computer could not connect to another console session on the remote computer because you already have a console session in progress". It is able to RDC to other machines on the network however. When trying to browse server A the win7 machine also is requested a username/password however both the domain account and local server A account do not work.
