"Microsoft has a problem. Vista, its long-awaited update to the Windows operating system, can't run the current version of SQL Server. The company is working on a SQL upgrade that is compatible with Vista - called SQL Server 2005 Express Service Pack 2 - but it's in beta and can be licensed only for testing purposes. Microsoft hasn't set a release date for the new SQL program. So companies looking to install Vista, which went on sale to corporate customers Nov. 30, are going to have to get their database management software someplace else."
