Win,

To echo some of what gellyfish has said, read the documentation. You have been advised to do this (regards MS SQL Server questions you have asked in the CB) many times by many different monks. You did not do it then, so I have no confidence in you reading up on this topic now. This has happened for various technologies you have posted questions about and asked about in the CB. Again your asking for advice that, historically, you have not taken.
