I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

There should already be a Login principal for your Windows user in SQL Server under Security | Logins
You can create a database user principal in the required database associated with the Login principal
CREATE USER <yourDBUser> FOR LOGIN <YourWindowsUser>

You can then give whatever permissions you required to <yourDBUser>
