Cannot make Multicast work

Roberto 646 Reputation points


I'm trying to enable multicast for OSD but I cannot make it work.

My environment:
Microsoft Endpoint Configuration Manager, Site versione: 5.0.8968.1000

On the client, the task sequence arrives to 'Opening multicast session for blah blah...'
and then fails with error code 0x80091007

On the client, I cannot find any logs apart from the X:\smstslog\smsts.log that ends with logs about diskpart.

On the server I see only the files mcsmgr.log, mcsMSI.log and MCSSetup.log, but they don't contain nothing relevant to my problem.

I already tried to

  1. 'Update Ditribution Points' for the multicast enabled OS image --> didn't work
  2. 'Delete' the OS image, then 'Add Operating System Image', then "Distribute Content' and then allow multicast on the OS image --> didn't work

Can anybody please help me debug and solve this, please?

Thank you and best regards.
