About adding or changing authorized group name to access the Symantec Protection Engine console
If you proceed with installation without entering a valid domain\group for Windows Active Directory-based authentication, then Symantec Protection Engine service starts as usual. However, you cannot access the Symantec Protection Engine console. You must go to configuration.xml and enter the required information. You can update the domain\group information by using xml modifier. Ensure that you type a valid domain and security group. You must restart the Symantec Protection Engine service after making the change.
