Since your administrator rights on all the databases disappeared and reappeared simultaneously, it's most likely that you switched workgroups using the Workgroup Administrator. Having the same name in different system databases isn't enough; permissions depend on both the user name and the PIN.
If you want to be able to use different workgroups to administer a database, you must create the user account with identical details in each workgroup. Since you already have a user account with the wrong PIN in at least one workgroup, you might have a problem changing it at this point. If you've already assigned permissions based on this account (with the wrong PIN), deleting the account and adding it back with the proper PIN will lose those permissions. (The permissions will still be stored in the database, actually, but you won't be able to get to them when you log on with the corrected PIN.)
The best procedure is to log on with another administrator account, go into each database in which the erroneous account has permissions, and remove all the permissions. Then delete and recreate your user account, and go back into each database and recreate the permissions for the new account.
Hope you can follow this. Without having any database or account names to mention, it's hard to distinguish which one I'm talking about for you.
