So, I have a Site to Site VPN from my Main office (192.168.0.x - Cincinnati) to my branch office (192.168.1.x - Chicago).
I was having some issues that prompted me to add domain controller at Chicago to remedy my problems. (DNS speed, and occasional logon issues)
The problem I am having is the server in Chicago (192.168.1.2) is receiving DNS responses from the Cincinnati server (192.168.0.8) but it is either denying/dropping them and I have no clue what is going on.
Below are links to screen shots of packet captures. The one screenshot is from Wireshark and it shows that the server is receiving the DNS responses. The other screenshot is from Microsoft Network Monitor (3.4) and it is showing that it is sending DNS queries, but not receiving any responses.
I appreciate any help you can give me.
