I have Windows Server 2003 and have enabled the Media
Server role. The default content will play on Media Player
ver. 6.4 using mms, but not on the newer players (series 9
or media player for XP). When I try to access the content
from a newer player using mms, a dialog box pops up saying:

"Windows Media Player cannot find the specified file..."

Conntent will play from:

Windows 2000 Server box with Media Player 6.4
Windows NT 4.0 Server box with Media Player 6.4

Content will not play from:

Windows 2003 Server box with Media Player Series 9
Windows 2000 Pro box with Media Player Series 9
Windows XP Pro box with Media Player for XP 8

The Windows 2000 Pro box mentioned above had Media Player
6.4 originally and I could play back the content. Once I
upgraded the player to Series 9, I could no longer access
it ("cannot find the file" error).

The firewall is disabled on the Windows 2003 server and I
have verified all protocols are enabled on the newer
players.

I can play the content on the Windows 2003 Server if I
open it directly, but not using a streaming protocol.

By the way, RealServer G2 is installed on the Windows
Server 2003. I have not been able to determine if this may
cause some conflict.

Any ideas would be appreciated.
