Using MMC (Active Directory Sites and Services) snap-in tool, you must first create a new site and subnet. You must then associate the subnet to a site and move the container object from “Default-First-Site-Name” or any other site to the new site.
Create a site. For more information, see Creating a Site.
Create a subnet. For more information, see Creating a Subnet.
Associate a subnet with the site. For more information, see Associating a Subnet with a Site.
Move the Active Directory server object of the domain controller from “Default-First-Site-Name” or any other site to the new site.
NOTE:Although the Active Directory server object is moved from one site to the other, the changes do not get reflected immediately.
The movement of Active Directory server object from one site to the other completes with the help of a crontab job (sites_dnsupdate.py) which takes care of creating 6 DNS records for each site. Use the sites_dnsupdate.py --logging option in the crontab job to capture the additional logs apart from the error and warnings.
NOTE:Ensure that you use the MMC (Active Directory Sites and Services) snap-in tool on a DSfW server only to move the Active Directory server object from one site to another. Micro Focus recommends you to not perform any other operation using this tool other than the move operation on the domain controller.
