Problem: Problems with a domain database (wpdomain.db) or post office database (wphost.db) can cause access problems for GroupWise Administrator and the GroupWise client, as well as cause message delivery problems. Database problems can also cause information in your system to be out of sync (for example, a user's information in one post office being different than that user's information in another post office).
Action: See "Maintaining Domain and Post Office Databases" in "Databases" in the GroupWise 6.5 Administration Guide.
