Multicast-enabled Distribution Points Stop Working after Upgrading to System Center 2012 R2 Configuration Manager

If you upgrade your hierarchy  to System Center 2012 R2 Configuration Manager and you have distribution points that are enabled for multicast stop working, look for entries similar to the following in the mcsexec.log: Error finding namespace: 0xc1210106

Make sure that before you upgrade the site or hierarchy, to make sure that Cumulative Update 3 or later is installed.

However, if you have already upgraded the site to System Center 2012 R2 Configuration Manager and multicast is not working on distribution points, perform the following procedure on each distribution point that is enabled for multicast:

  1. Edit the properties of the distribution point, and click the Multicast tab.
  2. Clear the Enable multicast to simultaneously send data to multiple clients option, and click Apply.
  3. Wait for the multicast configuration to be removed from the distribution point. You can verify removal by checking the MCSSetup.log file.
  4. Select the Enable multicast to simultaneously send data to multiple clients option, and click OK.
  5. Wait for at least one hour to make sure that Hierarchy Manager has reinstalled the multicast server.

Hope it Helps ,
