"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Apparently you didn't save/reuse the original cerificates. Do you still have them somewhere? And the original names.nsf? You might be able to fix this if you restore them from a backup.

Each new installation creates a new certifier id. All other certificates generated on that server stem from that id. When you open a database, the server tells you that the id you currently use does not correspond with the id the server knows from you.
