I am trying to add a new user/login to my database, but SQL server keeps telling me that I don't have permission to do that (error # 15247). Right now I am running Windows authentication, and am logged in as the same user as I was when I installed SQL server, and that user is the administrator for the computer system I am currently running. It seems like SQL server won't let me change anything having to do with the security of the system - I've tried changing to mixed mode authentication, but I receive the same error then as well.Help! ...
