day79 Posted August 6, 2018 Report post Posted August 6, 2018 Running version ConfigMgr 5.00.8634.1000 build 8634 and trying to test multicast on the same VLAN, but the task sequence fails with error code 0x800070002. It worked about 6 months back., but haven't checked it since and we've upgraded version since then. Checked the Operating System Image to make sure that Multicast is enabled, checked the Network Access Account is set, checked the DP multicast settings, and checked the TS for downloading content. See screenshots below. I'm probably missing something. Any ideas? Distribution Point - Multicast settings Operating System Images - Distribution Settings Task Sequence - Deployment Options Thanks!
