I'm getting the error below but have no idea on what the error is and how to fix it. Any suggestions?

Invalid server principal name.

The server principal name specified in the database catalog statement does not exist in the DCE registry. Because of this a DCE ticket could not be obtained for the DB2 server.

User response
Make sure that the principal name in the database catalog entry corresponds to the DCE principal being used by the DB2 server. It may be necessary to fully qualify the principal name.
