Active Directory or Domain Controller Disaster Recovery Question

[radvibes]

I am looking to implement something for AD backup in case of a disaster. We have everything centrally located in our corp office with no DCs in any branch.

We have a split (empty parent/child domain stucture)

Here is our setup...
Root domain - RootDC1 - Schema role and Domain Role Owner
RootDC2
Child domain - ChildDC1 - RID, Infra. Owner & PDC Role
ChildDC2
* All DCs are Global Catalogs.

What I am looking to do is to add one Root and one Child DCs to one of our branches over a direct T1 and make them GCs. I would leave all FSMO roles the way they are. In thhe case of a disaster completely wiping out the Corp network, would this be sufficient for allowing the AD stucture to survive if we took over the roles? Also do you forsee any replication issues with having the DCs in the branch.

Any thoughts, opinions, or other ideas on how to solve this problem are greatly appreciated.

thanks

should be ok, in case of disaster, u may seize FSMO to any DC survived in your 2 domain, and Schema master and DN master role as well.

to seize FSMO, refer ntdsutil at

keep in mind, u shoiuld have rootDC3 locate at branch, if you lost all DC on root domain, you are stuck.
