Neptuneit:
"Active Directory-Integrated Primary" and ours shows "Standard Primary", is going to be your problem.
There are several types of DNS Zones the main ones are listed below.
"(standard) Primary zone: This is the only zone type that can be edited or updated because the data in the zone is the original source of the data for all domains in the zone. Updates made to the primary zone are made by the DNS server that is authoritative for the specific primary zone. You can also back up data from a primary zone to a secondary zone.
"(standard) Secondary zone: A secondary zone is a read-only copy of the zone that was copied from the master server during zone transfer.
"Active Directory-integrated zone: An Active Directory-integrated zone is a zone that stores its zone data in Active Directory. DNS zone files are not needed. This type of zone is an authoritative primary zone. Zone data of an Active Directory-integrated zone is replicated during the Active Directory replication process. Active Directory-integrated zones also enjoy the security features of Active Directory.
If you check the DNS server with the AD Integrated Zone where your PCs with the 10.25.0.0/16 subnet is, are they updating those DNS records? From the sounds of it they are.
The server with Standard Primary Zone is only being updated by the DHCP server of its subnet, is can not recieve the updates from a AD Zone. You should change the (Primary) Zone to a Active directory integrated zone in order for the records to "sync" between sites. Also make sure you have set your DNS servers to allow replication or zone transfers between the 2 servers, this canbe checked under:Go to properties of the ZONE in question, "Zne transfers" tab and put a tic in the box.
For security purposes your should choose either "Only to servers listed on the Name Server tab" or "Only to the following servers". If you choose #1 make sur ethe server is listed in the "Name servers" tab or if you choose #2 specify the IP address of the server.
Let us know what happens.
Thanks
