Secondary (Backup) Domain Controller
Hi
I have set up a secondary domain controller using this guide.
"Step-by-Step Guide to Setting Up Additional Domain Controllers" http://www.microsoft.com/technet/prodtechnol/windowsserver2003/technologies/directory/activedirectory/stepbystep/addomcon.mspx
Everything went smooth, the Active Directory is replicated and working fine.
Now my question is, do i have to install DNS and DHCP on this Backup DC.
if I do then for DNS do i set it up exactly the same way as my Primary DC, if not please explain.
For DHCP if need to be setup, then do i assign the same scope and exclusion as the Primary DC.
Thanks

I'm not sure what you mean. You don't need to configure a "primary" DNS on each server. Try the following:
1. Configure your Primary server's DNS server properly.
2. Make sure the DNS zone is "AD-Integrated" (Right Click the zone, It should display there under the "General tab" - Displayed as the "Type".
3. Make sure your Backup DC is configured properly to replicate the AD database. This will include your DNS server from your primary DC!
4. Set up DHCP to use Split Scope as mentioned by mboppe above.
5. Set your DHCP to hand out both a Primary DNS server address AND a secondary DNS server address.
This way, if your primary DNS server doesn't respond, your clients will send their DNS requests to the backup DC.
Hope this clears thing up / helps.

A few more things:
1. When doing #2, Make sure your "Replication" is set to "All DNS servers in the Active Directoy Domain".
2. If you were referring to having DNS INSTALLED on your backup DC, then you are correct with that, you just don't need to configure your zones because that will be replicated with your AD when your DNS zone is AD-integrated.
3. You are also correct with the addition of the replicating partner as the alternate DNS server.
4. You are again correct with configuring each server to have it's self as the primary DNS.
I apologize for the confusion, I mis-read your comment.
