The VMM management server was unable to impersonate the supplied credentials.

Recommended Action

To add a host in a disjointed domain namespace, ensure that the credentials are valid and of a domain account. In addition, the SCVMMService must run as the local system account or a domain account with sufficient privileges to be able to impersonate other users.
