Here are some useful Windows short codes you cloud use to start the mmc and snap-ins from cmd and PowerShell.  You can use them in scripts or just impress your colleagues and boss (it works every time ;-))

Adsiedit.msc

ADSI Edit is a Microsoft Windows Server tool that you can use to view and edit raw Active Directory service attributes through the Active Directory Services Interfaces (ADSI) protocol. ADSI edit is suitable for editing a single object or a small number of objects in Active Directory. ADSI edit has no search facility. Therefore, you must know in advance the object that you are interested in and its location in Active Directory. Despite these drawbacks, ADSI edit is a popular tool because it is easier to use than many other tools for making direct edits to Active Directory.

ADSI edit is implemented as a snap in that runs in the Microsoft management console (MMC). ADSI edit will not run unless the adsiedit.dll file is registered. This registration will happen automatically if support tools are installed.
