If you have extended Active Directory (AD) for use with your AMT clients and Kerberos authentication, you may have issues connecting to the AMT WebUI for those machines when using Internet Explorer (IE). This is related to authentication settings.
If you experience this problem, you can first try another browser (e.g. Firefox) to see if you can connect to the WebUI. If successful, then you can try the following configurations in your IE settings.
- Tools > Internet options > Security > Custom level > User Authentication > Logon – Prompt for user name and password
- Tools > Internet options > Advanced > Security – Enable Integrated Windows Authentication
