Thanks Demazter,<br />

Yes, we want to configure the fourth server as a second domain controller and ensure that - should PDC goes down, all network / mail components will function as per normal.<br />
<br />
To confirm, apart from DNS and GC no other roles are required on the second DC to ensure continuous protection of AD and domain data?<br />

Hi Guys,<br />
<br />
We have three servers, PDC, Exchange &amp;&nbsp;TMG.<br />
<br />
We brought in a fourth &quot;PC&quot; only for backup of the domain server roles, as a backup for the domain.<br />
<br />
What is best practice i.t.o. hosting copies of the PDC server roles on our second domain controller, which is only a PC, but also running Windows Server 2008.<br />

This topic includes all things Active Directory including DNS, Group Policy, DFS, troubleshooting, ADFS, and all other topics under the Microsoft AD and identity umbrella.
