I have already written a small script to fix orphanusers while moving database from one server to anotherserver but the major problem is, that script just auto fix the login but can’thave login with the same password which old instance/server was having.
Microsoft has provided one small script to help you outin this situation. Look at the below script which will generate T-SQL for allusers available in current instance with password so that you can run that sameLogin script in another server/instance of SQL Server and have samelogin/password.

This script is copied from here.
Now all you need to do is, run stored procedure “sp_help_revlogin” with following command.
USE master
GO
EXECsp_help_revlogin
GO
This is really very helpful script which I have even used somany times. Keep it handy, you never know when you will need it.
