Moving DC to a New Box

Hi,
I Really need some Advise on this.

I had only one PDC on my Network, Then I was reading on EE on how to Move DC from one Box to another. So I got another Brand New Machine so I can move my DC to that Computer.
Before I moved DC on that I tested it out on my Own Box. So I ran DCPromo on my Box and Added Child Domain to the Exisiting Domain which was on my network already. it was kool I was able to see all the Users and Setting within this Child Domain Same as PDC.

Now I am confused.

 - if I  Add a New User within Child DC using my Machine, it will Add that user to PDC automatically?
 - if my PDC crashes I can use Child DC on my Box or it will Crash as well?
 - Why do we Need Additional DC's anyway?

So These are some basic Question making me Confuse.

Now How Would I move DC to the Brand new BOX. using the Same Technique i did with my Box? But Wait, What About DNS Settings. So far i had Dns Installed on the Same Box i have PDC.
Please Advise.

Thanks

Since you talk about DCPROMO, I assume you're talking about a Windows 2000 A/D domain.  


//- if I  Add a New User within Child DC using my Machine, it will Add that user to PDC automatically?

In W2K A/D it is a multi-master domain model, i.e. each DC is a peer and the data is automatically replicated from machine to machine.  If a DC in a domain goes down, the other DC(s) can take over the roles and handle the requests.  

// - if my PDC crashes I can use Child DC on my Box or it will Crash as well?

If your PDC (actually, it's just a DC which happens to have the PDC role at the moment) crashes, your other DCs will take over.

// - Why do we Need Additional DC's anyway?

1) So that you can have scheduled maintenance or unscheduled downtime, such as a crash, with a DC and not have problems with your network (users can still work).
2) To handle the load that is created when one has several hundred users logging on a 9:00AM
3) To provide DC services at physically dispersed sites linked only by slower WANs.

//Now How Would I move DC to the Brand new BOX

You run DCPROMO on the new box and get it integrated into the domain.  Then run DCPROMO on the DC you want to remove (if any) and remove it from the domain.

// What About DNS Settings

You can run as many DNS servers as you need in your domain.  I recommend having at least 2 DCs, both operating as DNS servers as well, for any moderate sized LAN for a business (e.g. more than 10 users).  

If you configure your DNS domains as 'Active Directory Integrated' then they will also play a part in this multi-master mode of working.  This is the recommended way to set up DNS in an A/D domain.  

Bonus: Also be sure to set up your DHCP on both servers and split your subnet between them in order to have a redundant DHCP configuration as well.  With multiple DCs, with DNS and DHCP range sharing, you can create a very robust network infrastructure.

Thanks That was Some Valueable information.

My concept about DNS is not so strong so currently I am running DNS Server where my PDC is isntalled, All I did was entered a New Zone for "Forward look up zone" same name as my DC.
Now When I will Install DC on new Box I Should do the Same Thing with DNS Server, after I run DCPROMO on the OLD box to remove DC?

My Router is working as a DHCP not Windows 2000.

Thanks again
