Mixing apples and oranges, I see. To log into SQL Server as ADS\dw,
you need to be logged into Windows as ADS\dw. That's what integrated
security is all about. By already being authenticated by Windows,
there is no need for SQL Server to authenticate you again. But you
cannot log into SQL Server with another Windows login than the one
you are logged into Windows with. You can only log into SQL Server
with an explicit username/password with an SQL login.

And dw now has sysadmin rights in the server, unless you remove
BUILTIN\Administrators.

First descide whether it's a Windows login or an SQL Login you want.
Next grant this user access to the server and database. Next you grant
him CONTROL on the database. (You are on SQL 2005, right?)
