You will definitely want to have at least on Windows login as part of the sysadmin role before you make any changes.

1. yes, connection strings need to change if they are not using trusted connections.

2. you can't. the Sa account cannot be used as that is for SQL authentication only. You need to add another user/group to the sysadmin role before you make this change.

3.see #2

Thanks for yours reply...

Windows authentication worked for me.

I added my domain user in sql server login, and then given sysadmin permission, so now i can able to access all the database and my domain user become a super user like sa. Also sql services running under this domain user.

I need some more details for the below.

1. select * from syslogins in master database, here my domain user display NULL password, so how to set the password on windows user?

2. how to give access database to windows user?

Thanks

When using Windows Authentication SQL Server does not require a password, it uses the token from your domain login to verify who are and if you have rights. SQL Server does store your Active Directory SID.

To allow a Windows user access to a database, you need to add a user, then map that user to the login you added.
