Could not start WebAccess server. Port 80 already in use.

When I start NetCrunch I get the following message "Could not start WebAccess server. Port 80 already in use."

Applies to 15.x 14.x 13.x 12.x 11.x 10.x 9.x 8.x 7.x 6.x

NetCrunch has its own built-in web server that uses port 80 by default. The message indicates that another web server, such as IIS, is running on the computer. To resolve the issue, you have to stop the other web server or change the port number that NetCrunch uses.

Go to Settings->NetCrunch System->Connections to perform any of these operations.
