Robert,
Have you tried USE TheDBC.DBC and see what rows there are that reference the problematic tables?
You might also crack open the DBFs in HexEdit and see what the DBC backlink points to.
>I've inherited a database. When running Validate Database I get the message
>'Alias 'XXXX'is not found' for several tables in the database. I've tried dropping the tables then adding them back to the DBC and I still get the message. Does anyone have any idea where to track down what is causing this. I've looked all over the DBC and I can't see what the problem is.
