There are 2 Domain Controllers running Windows Server 2003 x64 R2.
The installed roles of DC1 (10.0.0.1) are: File Server, Print Server, Application Server, DNS Server and of course Active Directory. The FSMO Roles are handled by DC1 as well, all five of them (RID, PDC, Infastructure, Schema Master, Domain Naming Master).
THe installed roles of DC2 (10.0.0.11) are: File Server, Application Server, DNS Server and Active Directory. The FSMO roles are assigned to DC1 so the DC2 FSMO roles point to the DC1.
Both Domain Controllers are Global Catalogs.
I am examing the scenarios where:
- DC1 goes down due to hardware/software problem but gets back online after few hours/days
- DC1 goes down completely with no chance to get back online ever again
- DC2 goes down due to hardware/software problem but gets back online after few hours/days
- DC2 goes down completely with no chance to get back online ever again
Apart from the two main DC's there is another Windows Server 2003 x64 R2 with no roles installed sitting there unplugged just in case of a disaster.
What I want to know is the best practice possible for each scenario and what steps (detailed, if you mind) should I follow to achieve all. Can you help me?
