    Not really. I routinely move users around and have to
    adjust logins/users for the different spids.

    The issue here is that I want the user on the dev server
    to have the right to restore a particular database. I do
    not want that user to be dbo on the production server.

    How can we get around what appears to be a requirement for
    the dbcreator role to be dbo on the db that is being
    restored from. e.g.

    PROD server db: dbo is the sa account
    DEV server : login DBA_Group has dbcreator role

    Suppose I make a backup of the PROD server db. and copy
    the .BAK down to the DEV server. At this point, login
    DBA_Group will fail to restore the db .BAK.

    I complete the restore on the DEV server using my sa
    login, and THEN do a sp_changedbowner to the login
    DBA_Group, and do a backup of that db . THEN I do a
    restore of the db using the login DBA_Group, it is
    successful. (Because now the backup .BAK file says that
    DBA_Group is the dbo?).

    Does this make sense?

    Is there a work around? Or something I'm missing?
