To do so on Windows, open up the command prompt.
Run netstat -ano | findstr :80
If you see 0.0.0.0:80 as a source address, remember the pid.
Run tasklist \v | findstr $pid
Replace $pid with the previous pid.
Shutdown the application, for assistance contact the applications administrator.
Once shutdown, deactivate/reactivate the primary hub wasp. The issue will be resolved.
