So maybe you haven't already heard that the SQL Server team has released a CTP (Community Technology Profile) of Service Pack 1 for SQL Server 2005. You can download the SP1 CTP at http://www.microsoft.com/sql/ctp_sp1.mspx.
But don't forget - THIS IS PRE-RELEASE SOFTWARE! Install it on test systems only...
