I'm trying to setup my computer so I can access my work computer from home via VPN.  But I'm having a problem when it comes to accessing my work computer.  I have no problems browsing the network or accessing my mail via the mail server on the network.  But when I try to access my computer, I get the following error:
      "\\computername is not accessible.  You might not have permission to use this
        network resource.  Contact the administrator of this server to find out if you have
        access permissions.  The network path was not found."

When I access this computer via a company dial-up connection, I get prompted for a Username and Password.  Then after entering that, I get in it with no problem.  On the VPN, I just get this error when I try to access my computer.  I was wondering since I'm accessing this via a network connection, if there could possibly be a setting in the Group Policy Settings or something that I need to change, so I'll get prompted for a login.

Also, when I access this via dial-up, I have to put my domain in front of my username when I log in to my computer:   Domain\Username

By the way, the computer I'm using is running Windows XP Pro and the one I'm trying to access is Windows 2000.

Yes you can check the following settings in your Group Policy.

Start==>Run==>type gpedit.msc and click ok.

Expand the following.

+Computer Config
  + Windows Settings
    + Security Settings
      + Local Policies
        + User Rights Assignment

Check both "Access This Computer from the Network", "Deny Access to this computer from the network."

On your home computer are you using the same username as the one at work with a different password? If so then it might be trying to use your username but is registering with a different password.  We have also had problems with users coming in via the VPN and then accessing resources under this condition and locking out their account at work within 3 minutes because every time they click on a resource it tries to use their local password.

I seriously doubt I can do anything with the group policy on the computer I'm trying to access, because it's a cooperate computer.

I tried creating an account with an identical username and password on my computer, but I still got the same error.

Well if you dont have network rights you need to contact your network administrator for assistance. Most fixes are going to require some kind of local administrative rights to that computer.

what I don't understand is why I get this error when I use VPN, and I have no problems when I use dial-up.

Are you running a software firewall on your computer at work? What ip address are you assigned when dialing in? What Ip address are you assigned on the vpn connection? If the vpn is setup to assign an ip address from a different pool of address and the firewall could be blocking you form accessing your computer.

well, now I'm wondering if the problem is just with the computer I'm trying to access.  Because, just to try it, I went to the mail server and tried to browse it's shared files.  When I tried to open the computer, I got a login prompt and I entered my user info, and it worked just fine.

I'll check to see if we can access the group policy settings in a while, I can't mess with it right now.

I checked the group policy settings and nothing was listed in the denied and "Everyone" was listed in the allowed.

Well, I think I may have just figured this out.  I noticed when I connect via dial-up, it uses a different WINS server than if I connect via VPN.  So I pinged my computer and got it's IP address using the dial-up connection.  Then I typed the IP into the address bar when I was connected to the VPN, and what do you know, I got a login prompt, and it connected!

After all this, my problems appearantly had nothing to do with my home computer, or my work computer, it's the WINS server or something at work.
