Overview

Some users may encounter login issues with the ARM Configuration Wizard or ARM Configuration/Client when entering their credentials manually. This problem can be associated with specific domain NetBIOS names, such as those containing dots, but is not limited to such cases. The following error may be visible in the logs during the login attempt.
