I have another strange issue, let me explain what is going on.
I have two machines (server1 and server2) with Windows Hyper-V server 2016 (the free one). Both connected in really simple Active Directory. Aditionally I have a management server with GUI server OS.
Both servers was connected to the same switch in my office, so I can establish replication of one VM located on server2 to the server1. Everything is going smoothly for couple of days.
Then I take the server2 and bring it to the remote site where already was Mikrotik router with IPSec VPN tunnel to my Office site. Just after that, replication stops working - so I let it running for some days to let settings settle down. After that days I removed the replication and try to make new one.
There Im getting error:
Hyper-V failed to enable replication.
Hyper-V failed to enable replication for virtual machine 'XXX': The connection with the server was terminated abnormally (0x00002EFE).
On the server1 - in my office - the secondary one, there is event:
Text: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)
On the server2 - the remote site, there is also only one event:
Text:Hyper-V failed to enable replication for virtual machine 'XXX': The connection with the server was terminated abnormally (0x00002EFE). (Virtual machine ID CABxxxxxxxxxxxxxxxxxxxxxx846)
Im trying to resolve it some days and situation gets that serious that I install the Wireshark on both Hyper-V servers and trying to catch the traffic - and request and response is not the same on server1 and server2.
1st http request is having incomplete response on the client side (server2)
2nd http request responses with "HTTP Error 400. The request is badly formed." but that response never reach the server2
That means server1 i sending a response that never hit the server2.
On my office site with server1 there is KerioControl, on the remote site with server2 there is a Mikrotik router interconnected by IPSec VPN tunnel, that is working well in all other tasks what Im using it for.
Im suspecting the Kerio Control security mechanisms such as antivirus or the IPS, but I already shut the features off and it is not working. Also logs are clear, no errors reported at all...
Please do you have some other things to try?
