Err Msg: Could Not Connect to Multicast Channel


The information in this article applies to:

  • Microsoft NetShow


When you dial in to use NetShow with multicasting, the following error message occurs:

Could not connect to Multicast Channel

NOTE: Internally on the network, NetShow is working.


If you are dialing into a Remote Access Server (RAS), the error occurs because the RAS server currently does not support multicast. You need to dial into a device that supports multicast, for example a Terminal server like Ascend Max 4000.

If you are not dialing into a RAS server, check with your ISP to see if they support multicast.


  • Every router between you and your server must also support multicast and be enabled for multicast.
  • Multicast is great for reducing bandwidth on corporate networks; however, it is not quite ready for the Internet.


For additional information, please see the Multicast white paper at:
