The issue appears to be the fact that the host is not listening on UPD 902 like the other hosts are. It does appear to be listening on TCP 902 though. I did make a trouble ticket last week and a tech worked with me on it and it appeared I had a firewall issue between the two LANs but that turned out not to be the case because I took the firewall out of the mix and it still isn't listening on UPD 902. Any thoughts? Basically this host just needs to be connected to vcenter long enough for me to migrate the VMs over to the HA cluster.
