SQL Server principal “dbo” does not exist,

Question

I am getting the following error

Cannot execute as the database principal because the principal \"dbo\" 
does not exist, this type of principal cannot be imp         


        

Answer 1

This may also happen when the database is a restore from a different SQL server or instance. In that case, the security principal 'dbo' in the database is not the same as the security principal on the SQL server on which the db was restored. Don't ask me how I know this...
