Today while checking the logins, just want to clear/clean logins which are no longer exists on NT domain.
To get the logins which are no longer exits run the following:
It will show you the list of SID and logins which are not exists. And then after that run the below command to remove that login.
Exec.sp_revokelogin ‘domain\Login name’
This is old commands and will be remove in future release… so if you are using sql server 2005 and above use below command which will be same as sp_revokelogin.
DROP LOGIN login_name
You can use the Enterprise Manager or SSMS for the same.
Go to Securities –> logins –> Right click and Delete login.
