I looked through the post on here before posting a question. So if this has already been solved please let me know.
I have two physical host running Win 2012 R2 STD
Each host is running three hyper-v machines, two of those replicate to the other physical host which they are not running on.
Physical machine 1 - 2012 R2 STD
Hyper -v machines: DC1 2012 R2 STD(not replicating) , File Server 2012R2 STD (replicating to PM2) , Scan Server 2008R2 STD (replicating to PM2)
Physical Machine 2 - 2012 R2 STD
Hyper-v machines DC2 2012 R2 STD (not replicating), SQL server 2012R2 STD (replicating to PM1), Printer 2012R2 STD (replicating to PM1)
I ran some windows update the other day and planned a reboot of the Host and VM's. That was on Dec. 4th. Today Dec. 11 th, replication failed, from hyper-v manager on PM1 I could not connect to PM2 and vice versa, all replication was critical. critical.
The first clue I had was that people could not print.
I checked the Hyper-V-Integration Admin log :
I did not see anything about Printer causing issues, however Scan states that the Hyper-V Data Exchange filed to connect to virtual machine Scan because the version does not machine the version expected by Hyper-V ( dfajde9ruewruei-df-a-asfd)
Framework version. Negotiated (0.0) - Expected (3.0);
To fix this problem you must upgrade the integration services. To upgrade , connect to the virtual machine and select Insert Integration Services Setup Disk from the Action Menu.
Under the windows log I got a warning for system: Networking driver in Scan loaded but has a different version from the Server version 5.0 client version 0.2.
unsupported config. To update select Insert Services Setup Disk from the Actin Menu
I called a friend and he suggested the do the same thing. Which I have completed. However, when I go back into Hyper-V manager for scan under Networking it stated Degraded (integration Services update required) I preformed a Refresh but nothing.
The question is why when I reboot my host and bring up my VM's do they crash within a week and replication fails and I get an RPC error when trying to connect to the other Physcial host. Why can people not print?
Is the Scan server causing all of this? If show I thought integration services update would fix this. I when through the steps but I don't believe it updated.
I have been reading these articles:

Any help appreicated
The Scan Server is actually Windows 2008 STD SP2
Build 6002
I also checked the system logs and have a bunch of DistributedCOM 10028 Errors
Dcom was not able to communicate with the computer PhysicalMachine2 using any of the configured protocols; request by PID
