Windows VPN troubleshooting is vulnerable to knee-jerk reactions when a user has trouble connecting. But it is important to look beyond VPN configurations as the first step in troubleshooting a customer's VPN connectivity and to recognize user-account related issues are also common perpetrators of connectivity problems.
Troubleshooting your Windows-based VPN
When a user has trouble connecting to a VPN (especially a new VPN), it's easy to assume that the VPN is configured incorrectly. However, before you start investigating configuration, it is best to begin by looking at the account that belongs to the user who is having problems connecting. There are a number of user-account-related issues that can cause a VPN connection to fail.

- Check user's account
- Check user permissions
- Check Routing and Remote Access service status
- Check port settings
- Check IAS certificate
