Thanks for all the help. Looks like a bad image. Out of curiosity what’s the largest image people have deployed using multicast? This one is 13GB.
From: Matt Wilkinson [mailto:[email protected]] Sent: 30 July 2014 08:39 To: [email protected] Subject: RE: [MDT-OSD] SCCM 2012 R2 CU2 Multicast After a bit of testing it appears the transmission drops as a client joins the stream. Is this normal? If too many clients join in close succession the speed is extremely slow. Network utilisation falls to 0.01% rather than the usual 70% .

This behavior points to unicast being used or network configuration in your environment have changed as well.

Multicast seems to grind to a halt when 30 or more clients join the transmission.
