SYMPTOMS
Microsoft Exchange 2000 Server users who use Outlook Web Access (OWA) may not be able to play Microsoft Windows Media attachments.

When the user clicks the link to the Windows Media attachment, Microsoft Windows Media Player displays the following error message:

The network connection has failed.

The following error code is displayed in the Details dialog box:

Error ID = 0xC00D0029, Remedy ID = 0x00000000

Even though the user can save the attachment to disk, and then play the saved file, the user cannot click the link to the attachment to play the attachment in Windows Media Player.



CAUSE
This problem may occur when the OWA front-end server has cookie-auth enabled.
