The database owner SID recorded in the master database differs from the database owner SID recorded in database '<Database>'. You should correct this situation by resetting the owner of database '<Database>' using the ALTER AUTHORIZATION statement.
This problem can arise when a database restored from a backup and the SID of the database owner does not match the owners SID listed in the master database.
To correct this issue, run the following command:
Alter Authorization on Database::<Database> to [<USER>]
To check who is the owner listed in the master database run the following:
,SL.Name as [LoginName]
FROM master..sysdatabases SD inner join master..syslogins SL
on SD.SID = SL.SID
Where SD.Name = '<Database>'
To check what SID is the DBO in the restored database run the following:
Where Name = 'DBO'
