Hi,
I'm working on a solution to deploy Hyper-V replica's. The situation is:
Forest1:
Hyper-V Cluster: Cluster1.domain1.local
Hyper-V Replica: Replica1.domain1.local (primary)
Forest2:
Hyper-V Cluster: Cluster2.domain2.local
Hyper-V Replica: Replica2.domain2.local (backup)
I have set up a Two-way Forest full trust between both domains/forests. I can access all resources in either domain from the other domain. Ping, Cifs, DNS resolution is all working in two-way direction.
Now when I try to set up the replica I end up with the error below.
Also in domain2.local in the eventlog I see the following event message:
Hyper-V failed to authenticate the primary server using Kerberos authentication. Error: The I/O operation has been aborted because of either a thread exit or an application request. (0x800703E3)
Source: Hyper-V-VMMS
Eventid: 29212
Looking for this error brought me to several posts to check e.g. ServicePrincipalName, Klist purge, but none helped. I personally think the multi-domain factor makes it extra difficult, but it should work according to Microsoft.
Hope someone can shed some light on this.
