What acces should be given to DBA admin in SQL 2005 server?


I need to give rights acces to a DBA admin group to SQL 2005 server on Windows 2003. I'm not familiar with this kind of acces.
Which rights should I give to let them able to manage the databases? Should I give them also acces on server?

What's the usual system admin does for this kind of request? Is there any proceadure that I can follow?

Does your dba not have to install and configure SQL?

SQL Server and Windows Server permissions are controlled seperately.
Adding a user to the Windows Administrator group does not implicitly give that user SQL Server admin rights.
