When you check your PVS replication status you see that some/all of your PVS Servers are missing from the replication status window and/or your load balancing “favours” a single device
This happen when the PVS servers cannot communicate properly with each other on multi-homed servers.
Adding the following reg entry will resolve this by forcing the soap/stream services to use the correct interface/IP address
Key : HKLMSoftwareCitrixProvisioningServicesIPC
String REG_SZ : IPv4Address
Value : IP of the NIC for IPC
I cant find any official documents form Citrix on this issue but works for me
