For Causes 1, 2, and 3
For Cause 4
On the Microsoft Dynamics CRM 2011 web server, open IIS Manager, and limit the CRM Website to one http binding or one https binding, or both. To do this, follow these steps:
Note The binding that should remain is the binding that is defined in the Deployment Manager. To check for the correct URLs, open the Deployment Manager, right-click Microsoft Dynamics CRM, select Properties, and then click the Web Address tab.
Note If Internet Facing Deployment (IFD) is used, the certificate that matches your IFD settings should be retained.
