Hello,
I have a question about RID pool and user account creation.
Our system has two server farms each of which has two DCs (i.e. 4 DCs in total).
Two farms are a primary and a backup, and the RID master DC resides in the primary.
The entire system is under a single domain.
When the primary farm fails and the backup farm takes over,
we do not want to seize the RID master role at the backup farm,
because the primary might recover later depending on the cause of the failover.
I read a Technet article which says that I can change the block size by changing a registry value.

I would like to know whether it would be possible to avert the RID block depletion on backup farm's DCs by setting a larger value to the 'RID Block Size' key (e.g. 5000) in advance.
In other words, is there anything that could potentially deplete
DCs' RIDs other than the account/computer/group creation operations we will perform
when our system enters the service (we will be creating no more than
several hundred user accounts, a couple hundred computers, and about a dozen groups).
We might create new user accounts while we are on the backup farm,
but the number of added users will not exceed 1000.
We will not create new computers and groups while on the backup farm, except perhaps a few.
Also, we will be incorporating AD CS, Exchange, and Skype for Business
to our single domain system.
(I posted the question to the HA forum, I've been suggested that this is a better place for my question, so here I am. Sorry for the double post.)
Regards,
Wanko
