When managing entities in more than one Active Directory, it is very nice to know that the Active Directory Manager Snap-in supports command line parameters select the domain (and if you want the domain controller).
(Further tweaking needs to be done using scripts like this one)
From the HOW TO: Change the Default Selection in the Active Directory Manager Snap-in. documentation:
Specify the Domain Controller Before Starting the Snap-in
To specify the domain controller to be used before starting the Active Directory Users and Computers snap-in, use the “/SERVER=” switch as a parameter to the MMC saved console (.msc) file. In the process of connecting to the server, the domain of which the controller is a member is automatically detected. For example, either from a command prompt or in the Open box, type:
dsa.msc /server=dc-01.domain.comSpecify the Domain Before Starting the Snap-in
To specify the domain to be used before starting the snap-in, use the “/DOMAIN=” switch as a parameter to the MMC saved console (.msc) file. A domain controller for the domain specified is located automatically and used as the default domain controller. For example, either from a command prompt or in the Open box, type:
dsa.msc /domain=childdomain.domain.com
