NTDS Settings in Sites And Services - General Questions

I have a WINDOWS 2003 network, I have several sites and I need to setup a replication plan for the DCs.

Im not certain that I fully understand the role the NTDS in the Sites and Services.


I have a main site, which hosts 2 DCs, one being the Domain Master.

Then I have a group of 4 dept offices, connected to the main site via wireless each dept with there own DC.

Then I have a group of 5 dept offices, connected to the main site via VPN over DSL/Cable line.

The DC's in the Main site can ping all DCs in the domain.

The DC's in the Wireless can ping all DC's in the Main Site and All DC's in the Wireless Site, but can not ping any of the DC's in the VPN sites.

The DC's in VPN can only ping the main site.

Each dept/site had its own subnet.

I did not originally setup this network, and when I origiinally accepted this job, I was told that all DCs in the domain had connectivity to all other DCs the enterprise.

In sites and services I setup a subnet for each subnet on the wan, setup a site for each subnet and associated that with the correct subnet, then I moved the DC's for each site into the correct subnet.

If I got into the NTDS setting for each DC's there are several DCs listed there, no pattern, some have all the DC's, other have a few DCs.

Its my understanding that I need to setup the replication partners for each DC in this area, this is what I did.

I setup the DC's on the MAIN site to replicate to all DCs in the domain.
I setup the DC's on the Wireless to replicate to the DC's in the MAIN location and the DCs on the Wireless.
I setup the DC's on the VPN to replicate only to the DC's in the MAIN.

Am I going about this in the correct way?
After making these changes, I checked back 1/2 hour later and several of the DC have not been replicated, do I need to restart each DC?
Any additional Information would be greatly appriciated.

thanks
Steve

you can just let the ISTG (InterSite Topology Generator) do it, but if you want specific servers to replicate, you can manually set up replication by adding a connection object to the server you want to replicate to.

If you want to set up a manual replication topology, i would suggest a hub and spoke system, or let the branch offices replicate with the HQ or central office, and then back out as necessary.

If you want to do it manually, you will need to turn off the ISTG.
