Why Additional Domain Controller

November 22, 2009 at 23:03:13
Specs: Windows 2003 Server R2
I have installed a DC – Let’s call it as DC1

I have installed a Second DC using (Additional Domain Controller for an existing domain controller option) – Let’s call it as DC2

Can anyone tell me:

1) If DC1(PDC) goes down, will DC2 (ADC) take over automatically????

2)When DC1 Goes Down, DFS can not be queried.

3) Why We Use ADC i.e ADC provides which Network Services ?

active directory failover
authenciation load balancing and failover
no such thing as ADC but other DC can failover IF you configure it to do so.

Of course this means;
global catalog enabled on both
dns server on both
dhcp scopes on both [one active one inactive]

if you want dfs to work as failover you have frs the folders you want [not apps] then if one dc goes down you change the pointer to the other.

If you want a higher level of failover you have to look at clustering and virtualization.

When DC1 goes down , then Acessing DFS from DC2( ADC ) says
"\\Domain Name\DFS Namespace not exists or can be queried"
Why DFS is not Properly Accessed from Additional Domain Controller. This Failover is Necessary For Me.
