Sql 2000 Connection Problems

I am trying to install Sql Server 2000 at the moment but when i try to connect to local Windows NT server i get this messege http://img293.imageshack.us/img293/3263/connection8rq.jpg and if i go to properties of the server i get http://img369.imageshack.us/img369/1335/properties9dd.jpg. I believe it is trying to log in using my Windows Authications.

Thanks for any help.
