SYMPTOMS

When you try to play back a video file or an audio file that is encoded with the H.264 video format or the AAC audio format, playback fails.

Note This problem may be encountered by Windows Media Player, by Windows Internet Explorer 9.0, or by other applications that rely on the Windows Media platform to play media files that use these formats.

CAUSE

This problem occurs because the Desktop Experience feature in Windows Server 2008 R2 does not include decoders for the H.264 and AAC formats.

RESOLUTION

To resolve this problem, install the Desktop Experience Decoder Update for Windows Server 2008 R2. This update adds the H.264 and AAC decoders to enable playback of these formats.
