Hello, I have two subnet 10.x/8 and 192.x/24 and a single AD configured on 192.x. DNS is configured on 192..x IP client computers of 192.x series can communicate with DNS but 10.x an not communicate now how can i achieve this Make sure that client computers in 10.x are pointing to the DNS server in 192.x as primary DNS server. Also, check your routes (To confirm that they are OKay, try sending a ping request to the DNS server using its private IP address) and check that there is no firewall blocking ICMP traffic and traffic to port 53. Use PortQry v2 for check. This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

Physical connectivity is needed but is not sufficient condition for you network structure. You need FQDN resolution and access to domain controller from the 10.x subnet. You can achieve working system by adding second domain controller into the subnet 10.x. Latest server operating systems allow for simple solution with RODC. Also you need to configure your active network devices to allow for communication between DC and RODC (time, replication, DNS, security, etc) Here is step by step procedure http://technet.microsoft.com/en-us/library/cc772234(WS.10).aspx
