1. Set up a VPN link between servers B, C & A.
2. Install DNS on all 3 servers.
3. DCPROMO servers B & C.
4. Point client PCs to the local server for DNS.

for W2K. you need to install DNS by yourself first and create all forward lookup zone as a secondary DNS and point to the w2k3(Primary). For W2K3 promotion. There is an option for install and confiure DNS inside during dcpromo. Good Luck

Please check my understandings.

Before installing the Windows 2000 server as additional domain controller in Workplace B and C, I have to install first (DNS- forward lookup zone as secondary), After that the dcpromo should be run to promote the server as Additional Domain Controller.

So after doing these steps, i can join the workstations in Workplace B and C into the domain.

I will check these procedure

Correct. Good Luck

To install the secondary DNS  in workplace B and C, Should i setup a VPN link with workplace A? ,  Becuase the Worplace A is 5 Km from Workplace B and C.
Without VPN link, I cannot install the secondary DNS in those places B and C?

And i am going to configure three sites.
