Microsoft Windows operating systems feature Virtual Private Network (VPN) client and server software designed to establish a secure connection from a remote computer to a private network. Installing third-party VPN software or updates after configuring the VPN service on a Windows 7 or Windows Vista computer may delete WAN Miniports and prevent the computer from establishing VPN connections. Reinstall the WAN Miniport driver in order to resolve the issue.

Skill level:
Moderately Easy

Things you need

  • Devcon.exe utility installed on the VPN server computer
