Dear Customer,
Thank you for posting in newsgroup.
According to the post, your want to know the process of demotion domain
controller and the best time to demote it. You also concern how to
calculate the time when the domain controller in remote site is considered
to be demoted.
Based on the experience, here is some information which may be helpful for
you.
Analysis and Suggestion:
=======================
1. For you concern about the process of demotion operation, you may refer
to "Process: Removing Active Directory" in the following link:
Active Directory Product Operations Guide
Chapter 3 - Detailed Maintenance Actions
http://www.microsoft.com/technet/solutionaccelerators/cits/mo/winsrvmg/adpog
/adpog3.mspx#E3HAE
Please note: During the demotion process, the Active Directory Installation
Wizard will attempt to transfer any remaining operations master roles to
other domain controllers without any user interaction. The wizard transfers
the roles to any available domain controller and does not indicate which
domain controller hosts them.
2. Because the demotion process will perform a Active Directory replication
between domain controllers between the two sites, and the time is
determined by the size of Active Directory and the performance of the WAN
Link speed. It is not easy to calculate the time when the domain controller
is to be demoted in the second remote site, which is connected to the main
site with WAN Slow Link. By the way, the demotion process between sites
will cost lots of bandwidth of WAN link, so it's recommend you not to
perform the demotion operation during the period of high network
utilization.
