VPN Error 609

The Remote Access Connection Manager (rasman) service is responsible for handling how your computer connects to the internet through services like dial-up and VPN. Sometimes, a glitch in this service can trigger VPN Error 609. This service often loads by default when the Windows system is turned on.

  1. Click the ‘Start’ button and then type ‘services.msc’ into the search bar and press the ‘Enter’ button.
  2. Scroll down the list of ‘Local Services’ to locate the ‘Remote Access Connection Manager’.
  3. Now ‘Right-click’ the service and select ‘Properties’.
  4. Click the drop-down menu next to ‘Startup Type’ and select ‘Manual’.
  5. Click the ‘Stop’ button under service status and hit ‘OK’ to disable the Remote Access Connection Manager.
