We have DNS server running on our domain at our main site. We have 4 remote sites connected via a vpn. So we have a domain controller at each location. DNS server is setup on each of those servers as a secondary zone to the main DNS server at our main location.
Weird thing going on, on our main DNS server, it shows all the computers and IP's of the main site and only two of the remote sites. However, the two remote sites that are not showing up, it at least shows the server for each site.
Now if you go to the remote site server and look at that DNS server, it shows all 5 sites and their computers and IP's.
Why would our primary DNS server be missing the two sites?
