DNS/DHCP Implementation

Hello:

In a 10-server environment that is running Windows 2000 server with 2 NT servers, in what order should DNS and DHCP services be implemented? Should all services be implemented on one server or different servers? Can more than one DNS Server be configured when the Active Directory is set up, and can DHCP be configured to automatically update DNS records?

I know that this is a bit involved, but we are having this debate at work and I would welcome the input from the Techrepublic community

Thanks,
