Summary

Windows VPN clients and VPN servers provide a large set of troubleshooting tools for diagnosing and gathering information about remote access VPN connections. VPN clients and servers can use TCP/IP troubleshooting tools such as Ping and Tracert. A VPN server can use authentication and accounting logging, event logging, tracing, Oakley logging, and Network Monitor.

The most common problems with remote access VPN connections are the inability to establish a successful connection and the inability to reach locations beyond the VPN server. Make sure to follow the processes and steps in this chapter closely— they are the same troubleshooting steps the Windows product team uses to test the Windows operating system, so you should be able to get all the issues worked out quickly and easily.
