Question : User and Group Permissions - "<unknown>"

I have a client who has a database designed by someone who has gone out of business.  Now we have a problem and I don't have permissions to change anything.  All objects show the Current Owner as .  We tried to join the only .mdw file we could find on the system but still no luck.

Answer : User and Group Permissions - "<unknown>"

I purchased an application called MDBRecovery by e-tech and it was able to remove all the user-level permissions and now I can do what is needed to make things work again.  The program was over 10 years old and has that much data in it.  The developer was nowhere to be found.  This product saved the day.  Thanks everyone.
