Question : Multicast session fails to open on secondary site server.

Hi.  I have multicast imaging working well on my primary SCCM site server.  I am having issues getting multicast imaging working at my two secondary SCCM sites.  I know I can multicast (tested with mcast.exe).  I have a manually specified IP range configured in SCCM.  

Advice?

Answer : Multicast session fails to open on secondary site server.

I did get multicast working by testing a different image.  The new image worked correctly.  

I also referred to this article to program the multicast address range.
