Microsoft's official position is that they don't support any SAN devices. But they do have couple of Knowledgebase articles that may help you get you more information: http://support.microsoft.com/support/kb/articles/Q221/7/56.ASP http://support.microsoft.com/support/kb/articles/Q237/7/67.asp The article http://support.microsoft.com/support/kb/articles/Q250/3/48.ASP does not seem to work. This had information on the lack of Microsoft support for Network-Attached Devices. Ramesh
