"hyper-v could not resolve replica server name".

Question

Hello everyone,
after having done the hyper-v replication I want to do the extended replication but on a server far away which has a different network address, so I created another windows server and I configured it as a router after I I linked the two servers, the ping worked great between them but when I try to do a extended replication I get an error message "hyper-v could not resolve replica server name".
What do you think is the problem or the mistake I made?
thank you in advance.

Hi,

Thanks for posting on our forum!

Based on your error message, your issue seems to be a common Hyper-V network issue. When we set up Hyper-V replica, primary server communicates with the replica server using the FQDN. The FQDN is resolved by querying the DNS Server. You should firstly check if you have a problem with the name you set for the server or if you used an IP Address or NetBIOS name instead of using an FQDN format. Changing the name or format will fix the issue. If you are using the correct format (FQDN), then its a DNS issue. If your replication is one way, then check if your primary server and replica server are configured with the correct DNS Servers. If your replication includes a reverse one, then you need to check your extended replica as well.

Besides, you can also go to Event Viewer>> Applications and Services Logs>> Microsoft>> Windows>> Hyper-V VMMS to check if there are any other error messages occuring.

Thanks for your support!

Joan
