I have two Windows Server 2016 machines running Hyper-V. I've successfully configured Hyper-V replica but I have a problem during planned failover. When I initiate the planned failover and check "Reverse the replication direction" box, it fails to reverse the replication direction, giving the 29262 error. Instead of using the FQDN specified in the replica configuration, it uses the format hostname.shortdomain as the server name (the "Pre-2000" domain name). When I manually reverse the direction and change the replica hostname to the FQDN, it works.
I believe this may have started when I migrated my Active Directory server from 2012R2 to 2016 and decommissioned my WINS server. My current domain functional level is 2008R2, although I don't know why that would matter.
It seems to me that Hyper-V should be using the FQDN and not the short domain format when reversing direction, but I don't know how to make it do that. Any help would be appreciated!
