Cisco VPN Error 442 Unable to Enable Virtual Adapter
Wasted about 2 hours of my time with this, so I’d like to spare you the same frustration.
- Go to “Start > Run”
- Type “cmd” to open the command prompt
- Paste the line below to disable the “Internet Connection Sharing (ICS)” (saving you the usual multiple button clicking hunt on Windows)
sc stop SharedAccess - Now open Cisco VPN and it should work.
