Was just wondering.. from what I can tell, Self Update will update either the local DC to the ADSelfServicePlus server or the one with the PDC role, and replication will immediately replicate it to another DC in the same site, from there it takes the usual replication time for the user's update to replicate to other Domain Controllers.
I did however hope that "Site Based DC", which allows you to "Configure the Domain Controllers to be updated on self-service operations." would allow you specify per OU DCs to be updated, now this may mean unlock/password reset functions and not My Info Self Update, but it should clearly state that, unless there's a bug with our Self Service?
I do have Site Based DC configured, however due to a spread of our server systems, I have enabled "DC Updator, Update Reset Password and Account Unlock status on all Domain Controllers" so as to avoid a user being "partially locked out" on one or more systems but not others due to their location. Does this render the "Site Based DC" configuration redundant?
Many thanks.
