RE: [ActiveDir] Forest Recovery Question

[Grillenmeier, Guido]

as Ulf said, a single domain is less problematic - you don't need to worry about GCs in single domains, since it wouldn't contain any other naming context that the DC already knows of.

 

with respect to seizing the FSMOs: this is different from transferring them - this can even be done if your target machine is not a GC (e.g. for Domain Naming master).

 

you certainly don't want to "re-enable" the GC before you've recovered one DC per child domain in your forest => the DC won't become a GC before it hasn't successfully replicated with the other domains. Again, in a single domain forest, this is a non-issue.

Assuming a complete failure of the Forest you need to disable the GC on multi-domain forests, recover each domain as needed, make sure that the domain is in sync, then reenable the GCs. You will not need to disable the GC in a single domain environment since the GC does not store anything but some indexes from the domain database.

Subject: [ActiveDir] Forest Recovery Question

Hi everyone,

 

I have read a MS whitepaper regarding Forest Recovery. The process seems straightforward.

 

My question is regarding GC's, it mentions that you should disable the GC function on a restored root DC if enabled as this may contain a partial replica newer than that of the domain it's authoritative for.

 

If the GC function is disabled, you can't seize the Domain naming master FSMO which I assume would mean you can't add additional child domains.  So would you have to disable then re-enable the GC function, seize the FSMO roles (ex IM) to the restored root DC (now a GC) before adding a second DC and making this a IM FSMO before recovering the child domains?

 

So my question is at what point would you need to re-enable the GC function on the recovered root DC? 

 

This is assuming it's a multi-domain environment...so would disabling the GC function be required in a single domain forest recovery? I would thought not.

 

thanks

 

James Carter
