OPC Communication Issue between 2 DeltaV Networks

I am trying to pass data between two DeltaV networks, one of them being V13.3.1 and one of them being 14.3.1 and am having issues. I have tried installing mirror on both systems to see which one i can get working first and am having success with neither location.  Both app stations are also my backup domain controllers for their respective systems so there are no local accounts. Looking through other threads i see a lot of reference to needing local accounts so not sure if that's part of the problem.  Before upgrading to 14.3.1, my system was 12.3.1 and i had OPC communication working between the two with no issues. Something has definitely seemed to change with 14.3.1. Any suggestions?

  • Does the deltavadmin password the same on both system ?

    On v14 side, does the user used by opc, member of deltav groups ? 

    I had a similar issue in the past, and I don't remember exacly what I did to fix the issue, but I remember more or less that we did a trust relationship between the domains, but may be not for mirror issue.
