It's a content filter form that helps find the subset of content (whether it be a webcast, prescriptive guidance, white paper, etc.) that best addresses a scenario, such as migrating from a non-Windows platform to a Windows server platform (i.e Linux to Windows Server) or interoperating with Unix using Windows Services for Unix 3.5.
