VPNs Keep You Safe Online

If your VPN server is rejecting client connections, the first thing you need to do is to check to make sure the Routing And Remote Access service is running. You can check this by opening the server's Control Panel and clicking on the Administrative Tools icon, followed by the Services icon. If the ping is successful, then ping the server again, but this time ping by the server's fully qualified domain name FQDN rather than by its address.

If this ping fails where the IP address ping succeeded, you have a DNS problem, because the client is unable to resolve the server's name to an IP address. As you may know, there are a lot of different authentication methods available to a VPN connection. When you do, Windows will open an empty Microsoft Management Console session. This will reveal a list of the available snap-ins. Now, the Routing And Remote Access snap-in should be added to the console.

Right-click on the listing for your VPN server and select the Properties command from the resulting shortcut menu. This will display the server's properties sheet. Select the Security tab and click the Authentication Methods button. This will cause Windows to display a dialog box with all of the available authentication methods. You can enable or disable authentication methods by selecting or deselecting the appropriate check boxes.

The method for checking the authentication method on the client end varies depending on the client's operating system. This will reveal the connection's properties sheet. Now, select the properties sheet's Security tab, select the Advanced radio button, and click the Settings button to reveal the available authentication methods. If the authentication methods appear to be set correctly, the next step is to check the technique by which the client is trying to connect to the VPN server.

If the client is dialing in to the server, rather than connecting through the Internet, it could be that the remote user has no dial-in privileges. You can check the privileges either by looking at the Dial In tab on the user's properties sheet in Active Directory Users And Computers, or by looking at the domain's remote access policy. This would also be a good time to verify that the user actually knows how to establish the VPN connection and that the user is using the correct username and password.

This may sound obvious, but if your domain is running in Windows Native Mode, your VPN server needs to be a member of the domain. If the VPN server hasn't joined the domain, it will be unable to authenticate logins. You also need to take a look at IP addresses. This IP address has the same subnet as the local network and thus allows the client to communicate with the local network. At the time you set up the VPN server, you must either specify that the server will use a DHCP server to assign addresses to clients, or you can create a bank of IP addresses to assign to clients directly from the VPN server.

In either case, if the server runs out of valid IP addresses, it will be unable to assign an address to the client and the connection will be refused. If you right-click on the VPN server in the Routing And Remote Access console and select the Properties command from the resulting shortcut menu, you'll see the server's properties sheet.

The properties sheet's IP tab contains radio buttons that allow you to select whether a static address pool or a DHCP server will be used. If you select the DHCP server option, you must select the appropriate network adapter from the drop-down list at the bottom of the tab. Now that I've discussed reasons why a connection might be refused, let's take a look at the opposite problem in which unauthorized connections are accepted.

This problem is much less common than not getting connected at all, but is much more serious because of the potential security issues. If you look at a user's properties sheet in the Active Directory Users And Computers console, you'll notice that the Dial In tab contains an option to control access through the remote access policy.

If this option is selected and the effective remote access policy is set to allow remote access, the user will be able to attach to the VPN. Although I have been unable to re-create the situation personally, I have heard rumors that a bug exists in Windows that causes the connection to be accepted even if the effective remote access policy is set to deny a user's connection, and that it's best to allow or deny connections directly through the Active Directory Users And Computers console.

Another common VPN problem is that a connection is successfully established, but that the remote user is unable to access the network lying beyond the VPN server. By far, the most common cause of this problem is that permission hasn't been granted for the user to access the entire network.

If you have ever worked with Windows NT 4. This particular setting doesn't exist in Windows , but there is another setting that does the same thing. To allow a user to access the entire network, go to the Routing And Remote Access console and right-click on the VPN server that's having the problem.
