j1mmyd3an Posted September 20, 2012 Report post Posted September 20, 2012 Hi there, I've got a question about boundary groups, multicast and multiple DPs. I have a boundary group that consists of multiple IP ranges. In this boundary group there are 2 DPs: 1 x Windows Server 2008R2 - multicast enabled 1 x Windows 7 SP1 - multicast not supported These 2 servers exist on different networks. The main reason for having the Windows 7 DP is for OSD at a small location. Can I leave the WIM file multicast-enabled, or do I have to turn that off now? The reason I ask is because my deployments are failing with a hash incorrect error unless I disable the multicast option on the WIM. The clients on the same physical network as the WIndows 7 DP will try the multicast option from the Server 2008R2 box first and fail. I was hoping that they would fail over to the Windows 7 DP at their location but that's not happening. When I disable the multicast option on the WIM they try the Windows 7 DP first and all goes well. Maybe I'm trying to do something that isn't supported. I've already thought of a possible workaround but I just wanted to ask first. Lastly, I just wanted to say thank you for all the support this forum has provided me. Absolutely invaluable. Cheers!
