Q171766 - Err Msg: Could Not Connect to Multicast Channel

Err Msg: Could Not Connect to Multicast Channel

Q171766

The information in this article applies to:

Microsoft NetShow

SYMPTOMS

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.

WORKAROUND

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.

Notes:

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.
