how to add a 2nd DC to a site

I had a few questions about adding a second DC to a domain. This is with Server 2003 and all machines are in the same site.

1. Does it need to have DNS loaded on the server?

2. Once it is up and working properly, how do the other workstations know that there is another logon server available? Do I have to add it via DHCP?

1. It doesn't hurt to have DNS on the New DC, Infact I would recommend it would increase server resiliency for DNS
2. Once you have it up and running, you don't need to do anything specifically. If you have made the second DC with DNS and you are using DHCP to populate DNS entries at client then you would have to add another DNS entry for this new DC.

Hope that helps.

So if DNS is not loaded on the server, than I should not have to do anything. It wil find the logon server automatically?
If you are not making the new DC a DNS as well then yes you really don't have anything special. Just make sure that this new DC point to the correct DNS( you current and only DNS) Server in its network configuration.
Also give it ample time to replicate.

If you like to make sure that the new DC infact has made itself available to as a DC, keep a look out for 13516 event in the FRS log. 13516 event indicates that the new server has advertised itself as DC and has shared its netlogon and sysvol folder, which are used for user logon (among other things).

The server does not NEED to have DNS or Global Catalog, but it would be very benificial for it to have both, that way you have built in redundancy. If you do add DNS then you should add the IP of the server to the DNS servers list via DHCP and have both servers point to themselves as their preferred DNS server and to each other as the alternate DNS server.

Wether or not you add DNS then there is no need to do anything, the DC will add its LDAP record to DNS which will then be used by clients to locate Domain Controllers, there is no need for you to do anything to make this happen
Above furnished information is good but you might require help from below sites::
