VPNs don't always open allow all the ports needed for more complex needs like AD replication. Check out this Microsoft articel: <a href="http://technet.microsoft.com/en-us/library/bb727063.asp" rel="ugc">http://technet.microsoft.com/en-us/library/bb727063.asp</a>.<br />

Hi there, I have a domain controller (win 2003) in another city. &nbsp;I have them connected via two sonicwall TZ210 routers via a VPN. &nbsp;One is on 192.168.2.1, the other (the main office where the primary domain controller is) is 192.168.1.1. &nbsp;I can ping the server, but the DNS only seems to be working with a FQDN i.e. nslookup server.abc works but nslookup server doesn't. &nbsp;I can't join the domain from a computer on the 192.168.2.1 domain either. <br />
<br />
I have the 192.168.2.1 DNS servers pointing to 192.168.1.6 (which is the PDC). &nbsp;I am not sure where I go from here? &nbsp;Should they both be on the same subnet for this to work?

One domain two cities.

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
