Communications Server “14” Beta – “HTTP Error 401.2 – Unauthorized” when launching Control Panel

Here’s an error I ran into while working with CS 14 Beta:

1. Fresh install of CS 14.

2. Started all services.

3. Launched Communications Server Control Plane and got this page:

HTTP Error 401.2 – Unauthorized

You are not authorized to view this page due to invalid authentication headers.

To get the Control Panel to load:

1. Open up the Internet Options window and navigate to the Security tab.

2. Open up the Local Intranet sites.

3. Click on the Advanced button.

4. Add the page to the zone.

5. Refresh the page and you’ll see that it loads now.

Not sure if this will be a problem in beta refresh or RTM but just in case it does, this would be something I’d try.
