How to disable the authentication on the Diagrams tab in Power Monitoring Expert 8?

Issue:
In Power Monitoring Expert 8, a user is prompted with an authentication dialog when accessing the Diagrams tab (or the <servername>\ION webpage) The user is required to enter the windows credentials in order to access. 

Product Line:
Power Monitoring Expert 8.x

Environment:
Power Monitoring Expert Web Applications

Cause:

Power Monitoring Expert 8 introduced password protection for the ION virtual root (the Diagrams tab in Web Applications). It requries that user enter their windows credentials in order to authenticate with the webpage. 

Resolution:
*Warning: Take backups of any files prior to modifying them. Ensure the backups are in a location that will not be overwritten (i.e. the Desktop).

The authentication requriement can be disabled by editing the \Power Monitoring Epxert\system\webreach\web.config .

1) In the web.config file locate the following line of code: <deny users="?" />

2) Change this to: <allow users='*' />

Once this is done, you can access the ION virtual root without providing credentials.

Additional Note;
If a browser is run on the PME server, the ION virtual root will always be available without requiring authentication. The authentication dialog will only apear if the browser is run on a remote machine.
