When we originally set up our tree/domain, we only had one Domain Controller(DC). We set up both a dynamic forward and dynamic reverse zones. We have since added a 2nd DC. Yesterday when I looked on the Alternate Domain Controller (ADC), I noticed that the forward lookup zones were replicated fine, but the reverse lookup zones were not replicated. I haven't been able to find out why this is happening. My question is how do I fix this problem and why is it happening?
