Windows Media Services 9 Series can connect to Windows Media Services version 4.1 and Windows Media Encoder version 4.1, that were released with Windows 2000 Server, or to the versions that were subsequently made available for download from the Windows Media Technologies Web site by using the HTTP protocol. (MSBD is no longer a supported protocol.)
Windows Media Services 9 Series does not support using versions of Windows Media Technologies shipped prior to Windows 2000 Server.
