After you add servers with Kerberos authentication, the servers might not be found because they are not added correctly.


When you try to connect to a server, the server is not found in Kerberos database.

No valid credentials provided (Mechanism level: No valid
credentials provided (Mechanism level: Server not found in Kerberos
database (7)))


This error might be caused by domain or mapping problems, or because of a DNS problem where the service principal name is not built correctly. Kerberos authentication does not workwhen the destination is an IP address.


When you add a PowerShell host using the Kerberos authentication type a DNS or NetBIOS destination.
