KB135127 - Trust Relationship Confirmation Messages Different

When you establish trust relationships between two Windows NT domain controllers using User Manager for Domains, the following message appears:

Trust relationship with <other domain name> successfully established.

When you establish trust relationships between a Windows or Windows for Workgroups client computer using Windows NT 3.5 and 3.51 Server Tools and a Windows NT domain controller, the following message appears on the client computer's User Manager for Domains:

Windows NT 3.5 Server Tools

The trust relationship could not be verified at this time. If you find that it was not established, contact the administrator of the <other domain name> domain and verify that it has permitted <your domain name> to trust.

Windows NT 3.51 Server Tools

You have changed a trust relationship between domains. This client cannot verify changes to trust relationships. If you find that it was not established, contact the administrator of the <other domain name> domain and verify that it has permitted <your domain> to trust.

The message displayed by User Manager for Domains in Windows NT 3.51 Server Tools explains why the trust relationship cannot be verified, whereas the User Manager for Domains in Windows NT 3.5 Server Tools error message does not.
