What is the proper network configuration for Replication on two NIC's

I am working on setting up a Network/Domain where I will have multiple NIC's in each server. I planned to have 1 NIC for management and the others for VM's, Clusters and Live Migrations. I created two servers and joined them to the domain. The NIC was set to 10.16.3.1 network. They can talk and see the domain controllers no problem. But then I added Virtual servers and put them on a different subnet of 192.168.45.1. Then I went and enabled Replication. I was able to find the servers and set it up with each other but then when I tried to actually replicate it fails and says it can't resolve the name of the Hyper-Visor. What is the proper way to configure this so replication will work?

no resolve sounds like a DNS or routing issue.  Are they in the same DNS zone?  pointed at the same DNS server?  Is there a router to route traffic between the two subnets?

The Host has a DNS server and is logged into a Domain. The Virtual servers are not on a domain and just have a gateway. That is why I am not sure if the Replication in Hyper-V is using the Host or the Virtual servers to route that traffic.

In the future a lot of the Virtual servers will have their own DNS as well. This is why I am trying to figure out the proper way to set that up.

Replicating Virtual machines is Hyper-V host responsibility

The replication attempt failed because source Hyper-V host unable to communicate with target Hyper-V host

U need to enable / open Ports (TCP 80 /443 / ICMP) between source and target Hyper-V servers
Probably you may need to put routes on router to enable communication
Also you can put hyper-v server IP for replica

Check below post for step by step setting up replica

It is a DNS issue due to the multiple NICs but I can't figure out how to resolve it.

Where are you routing traffic between the two subnets?

Are we talking about Hyper-V replica here or are we talking some direct replication between the virtual servers?

If you have two virtual switches on the same subnet, does hyper-V support aggregating the virtual switches? (I know vmware can do this).  If you cannot make the two virtual switches on the Hyper-V configuration perform as one single aggregated virtual device, then you will need to route traffic between the two networks.  In this case, I think your virtual servers will need to be on different subnets 192.168.45.1/25 and 192.168.45.128/25 for example. (unless you aren't into Variable subnetting).  you can't route traffic between two networks on the same subnet but separated.

I am not following you Trenton Knew. I can ping the IP address and I can ping the name of the Host as well from both sides. But the replication still won't work.

One other thing I didn't mention though and this might be the problem. My Server names are very long. For example the host are name stuff like JSHV-PAI1-0102.bignetwork.com. When I joined them to the domain it said it would shorten it for netbios. So when you find it in Active Directory it is listed as JSHV-PAI1-010 and that is it. So it shaves off the last number. I saw another post that said this could be the problem. How do I fix this?
