    Replication takes into account specific values and follows a pre-defined algorithm to insure replication consistency among domain controllers to reduce or eliminate divergence, such as the following:

    High-watermark

    • This is a value that the destination domain controller maintains to keep track of the most recent change that it has received from a specific source domain controller for an object in a specific directory partition.
      • This value prevents irrelevant objects from being considered by the source domain controller with respect to a single destination.
      • To see the value of the High-watermark, run repadmin /showreps /verbose and look for each line that starts “USNs:”. The high-watermark USN is the number that is followed by “/OU”.
