The Chapter On SQL Server 2005 Service Pack 2 Is Closed

This is the final word on SQL Server 2005 Service Pack 2 (at least from me, I promise)

It is all explained here: http://blogs.msdn.com/psssql/archive/2007/04/06/post-sql-server-2005-service-pack-2-sp2-fixes-explained.aspx


So as you can see from that link, after applying the critical updates you should be on either build 9.00.3054 or 9.00.3159
