Error 21002 [SQL-DMO] User 'already' exists

I have restored a database. Now I am trying to reset permissions on some accounts and this is the error I get. Even when I delete and re-establish acct, I get same thing. Can anyone help
ThanksSeems you want to read about sp_change_users_logins in Books Online. For a GUI on top of the
command, see:
