Where does the ARS MMC console read the domain info from?
The ARS MMC enumerates service connection point (SCP) objects published by ARS services in container:
CN=Enterprise Directory Manager,CN=Aelita,CN=System,DC=domain,DC=com
(where domain.com should be replaced with the domain name.)
The MMC looks at the modification time of the connection point and if this time is not older than 48 hours from current time ARS itself updates the SCP every 10 minutes.
