How to Troubleshoot VPN With Windows XP SP1
A virtual private network (VPN) is a secure network service operated and available through the Windows XP operating system. VPNs allow individuals to connect to various aspects of a network by using a virtual network such as an Internet connection. The private network data is passed through the virtual network first, ensuring privacy in unsecured situations such as public library computer networks. Occasionally, VPNs may not connect or work as planned. Employ troubleshooting strategies to resolve these issues and re-connect to your VPN.

Enable VPN traffic through your firewall. Some firewalls may misinterpret virtual private network traffic as malicious, and may prevent your computer from connecting to the VPN. Launch your personal firewall and make sure server port 1723 and client port 1024-65535 are enabled. If you are unsure how to enable ports in your firewall, consult your firewall software's user manual.

Tips & Warnings
When setting up the VPN, choose "Anyone's use" only if you want the VPN connection to be available to all individuals who use your computer. This may make personal data vulnerable if you are using a public computer.
