Why do ISA clients have trouble connecting to my server using the MMS protocol?

The default port that the Microsoft Media Server (MMS) protocol uses is 1755. Some ISA clients may have trouble connecting to this port because ISA uses different connection criteria for ports above 1023.

You can correct this problem in of the following ways:

• Change the port to which the MMS protocol binds. For more information about configuring the MMS protocol, see To configure the WMS MMS Server Control Protocol plug-in.
• Create a file called Wspcfg.ini and save it to the folder named %systemroot%\Windows\System32\Windows Media\Server. The file should contain the following text:

  [WMServer]
  LocalBindTcpPorts=1755
  LocalBindUdpPorts=1755
