First you must configure Windows Small Business Server 2003 to function as a VPN server, which you can do by running the Routing and Remote Access Server Setup Wizard. Once you have done that, you can modify the properites for a user's account to allow the user to connect using a VPN client on his or her computer. To do so, take the following steps:
- Click on Start
- Click on Administrative Tools
- Click on Server Management
- Click on Users
- Right-click on a username and select Properties
- Click on the Dial-in tab
- Click on Allow access
- Click on OK
- Click on File then Exit to exit Server Management
If the user doesn't have permission for VPN access, the user will see a window appear with the following error message when he or she attempts to establish a VPN connection:

Error 649: The account does not have permission to dial in.
