Domain replication over different networks

Hi Experts,

I need some help expanding my company's current backbone to a new network.

Okay, the current (local) layout is as follows:

I have a 2003 domain with one 2003 Srv domain controller. The 1st DC server functions as a DNS, DHCP and Wins host and the network ID is

I now have a new remote site that I need to attach to the current network. This is going to be done over a dedicated 64K line (the fastest I can implement unfortunately!). The remote network will be part of the original domain with network ID

I have 2 Cisco routers on both ends of the 64K line that attaches directly to the physical network on both sides.

The remote network also has a domain controller that replicates with the 1st domain controller. This has been tested over the 64K line and its works okay because our Active Directory DB is rather small and very few changes needs to be replicated.

My question is with regards to the setup of DNS on the remote server: do I need to create a new zone for the same domain on the new server or do I need to replicate with the DNS on the 1st domain controller?  I tried the latter option but for some reason names on the remote network resolves correctly from the local network but not the other way around.

Any help or ideas would be much appreciated.

Many thanks!

    You need to replicate the zone from the main DC.
    You have two ways to do that: either a secondary zone, which is a write-protected copy of a primary zone (if you have a standard primary zone on your main DC).
    Or you change your zone(s) (if you haven't done so already) on the main server to AD integrated (in the properties of the zone); then all you have to do is install the DNS service on the second DC, and wait for the replication; the AD integrated zones will appear automatically, do NOT create them manually.
    AD integrated zones are usually the better choice.
