Unable to delete domains

JoshWhite

I have an issue with unused domains in my file geodatabase.  I have partially implemented the Local Government Information Model so it added a number of new domains.  Now I have some old domains that I would really like to remove to avoid any confusion.  I have come up with a list of about 8 domains that I would like to remove.  Trouble is that I always get an error message:

Failed to delete a domain from the database.
The domain is used as a default domain.

I cannot gaurantee that I don't still have a default set somewhere but I don't think I do.  I can't understand what I need to do to remove this "lock" so that I can clean things up.  It seems that this is just a waste of space and possible performance killer.

I'm encountering the same thing.  I'm calling them "phantom domains".  I've run python scripts to check for orphaned domains and after each of these domains I cannot delete, there is a whitespace in the list.  I've also noticed that when assigning domains to a field, I have a series of blank spaces before the domain list contents show (the exact same number of blank spaces of domains I cannot delete from my database).  Anyone else encounter this?
