Expanding the rubberband....Microsoft SQL Server 2005 SP2a just got released. You can obtain the Service Pack here: http://support.microsoft.com/kb/913089 Why would I announce this on a Microsoft CRM related blog? Well since the new Service Pack has a lot of improvements that could be useful when working with Microsoft Dynamics CRM 3.0, Office 2007 and Vista. So assuming you are working with our latest version (V3C) on a Vista Machine with Office 2007 I personally would recommend to upgrade your SQL Server 2005 with SP2a, but keep in mind that it is not officially supported yet by the product(team).
SQL Server 2005 SP2a has improvements for Analysis Services, Reporting Services, Replication and much more...you can see the full list here: http://download.microsoft.com/download/2/b/5/2b5e5d37-9b17-423d-bc8f-b11ecd4195b4/WhatsNewSQL2005SP2.htm
