SQL Server 2008 - Login Fails Using Windows Authentication for Member of Server Administators Group

A coworker wiped SQL Server 2005 and installed SQL Server 2008 on a server named TEST.  I'm trying to login to the new SQL Server 2008, but the login fails.  See the text below.  
1. My user account is a member of TEST\Administrators.
2. The SQL Server is installed in mixed mode.

TITLE: Connect to Server

Cannot connect to GIS-TEST3.


Login failed for user 'GIS-TEST3\danaj1'. (Microsoft SQL Server, Error: 18456)

If you have the sa account at hand, that is much easier - assign the SysAdmin role the Local Admin group.

you must add 'GIS-TEST3\danaj1' to sql server logins
--there is no builtin\administrators login  in sql 2008 after install anymore (like in sql2005 and before) (way to give local wind admins sql server sa access)
contact the person who installed the sql2008 and ask to grant you sql permissions
With SQL server 2008 the Builtin Administrators group (local admins) is no longer SQL admns.  The login used to install the database should be able to log in to the database.   If you can't use that login use the procedure in the link in the first answer.  
If you want to operate like in 2005 create a Windows local group - TEST\SQLAdmins - and create a SQL login with the sql admin role for that group.  Then any member of the group will be a SQL admin.
