Disabling caching of file share access credentials

When users make a VPN connection into our network, they can see the file shares even though they are not logged into the domain.  To access a file share they should be prompted for user name/password.  The first time a user connects from a given computer, the usr/pwd prompt comes up but not for subsequent attempts to access to the same share.   The problem that comes up is that if a different user makes a new VPN connection for the same computer, he is able to access the share without entering usr/pwd because the first users credentials are cached and submitted.  Since the first user may have access to a share that the second user should not, this is a major problem.

I have been searching for a setting at the server level to cause all share accesses to require a password, or at least set a timeout afterwhich credentials must be reentered.  As I understand, GPO won't help in this situation becuase the users do not log into the domain.

Any know how to disable or limit this caching with a server setting?

Think this one still works post XP....

Disable Storage of Credentials and .NET Passwords

Are these systems sharing a User account? If they are, individual user accounts would render this a moot issue, as 1 user's credentials for a share are stored in their own storage, and are not visible to another user account.....

Oh, and these are CLIENT side changes....

My various researches into this indicate that there is no server-side setting outside of GPO to do what I want.  So I have an answer that I can go forward with.  johnb6767's links are right on as far as dealing with it on the client side so I am accepting his solution.
