VPN Remote Access Issue - Can Login, but can't access local resour

[PARRISH]

I want to log in remotely to a SBS 2003 Domain which is fully patched. For that I want to login from my XP pro machine at gome which is also fully patched. The problem that I am facing is that, from home, I am able to login into my SBS 2003 server remotely but I cannot do anything once I am in there. When I use Outlook 2007 or Outlook 2003 while logged onto Jupiter through the VPN tunnerl, then I get a message popping up continuously that says "need password". Even though entering the passwords many times, nothing works. If anyone has any solution for this problem, then please share it with me. Thanks.

I think that the issue could be related to Windows Firewall on the desktop machines, so I went into the GPO and disabled the Firewall. After restarting the machines, I checked that the firewall was disabled and then tried to login again, but still cannot access the network resources. I checked the issue in the security event log that whenever my remote machine sends its login credentials to access the Exchange Server, the username, password and domain information is left blank. Any ideas?

There is an article that describes the most common setups that you can use to set up Windows Small Business Server (Windows SBS) 2003 for Internet access by using one or two network adapters. For more information, visit the full article here - http://support.microsoft.com/kb/825763/en-us
