Trouble mapping a drive over a VPN

I am trying to get a Laptop that connects via VPN to our server (windows 2000) to be able to connect to the shared folder on said server.  

things that i know that might help..

- I can remote desktop to the server.
- I can ping the server and any computer on the network.

When try to use windows to map the drive, it apparently can see the drive because i get prompted for a login/pw.  When I log in with the correct name/pw, it just keeps popping up new login prompts.  almost like it is the wrong password or username but i am sure they are correct.  i have tried "localmachinename/username" and password and the same thing happens.  have also tried "username@domain.com" with the same results.  

Any help is appreciated.

It is possible it may not be able to resolve the name. This is common with VPN's. Try first connecting by IP address. In a browser window or at a DOS prompt enter
\\<IPAddress\Share     such as       \\192.168.123.123\Sharename
If that should work, we can 'fix' name resolution.

Also if the computer is a member of a domain and the computer from which you are connecting is not you may need to add the domain name. To do so in the logon box use       DomainName\DomainUserName

Final option, I can think of, sometimes if the MTU (Maximum Transmissions Size) is sett too high you Will be able to connect to a share but not open it. If this is the case usually it would accept the password but go no further. If you would like to 'tweak' that, have a look at the following articles explaining the problem and how to adjust the MTU size. You should also adjust the router to the same at the client site.
