Everyday I need to access some of the Administrative Tools on a Windows Server. An easy way is to memorize their launch file name, and simply hit Win+R, type in the filename and presto - instant access. You can of course go by the menu as well, but I find the first way much easier. Below is the my most frequently used tools and their launch file name.

dsa.msc

domain.msc
 
Active Directory Management
admgmt.msc
 
Active Directory Sites and Serrvices
dssite.msc

compmgmt.msc
