In tip 6734, I described how using Saved Queries provided you with access to a consistent set of directory objects.
Another Active Directory Users and Computers feature allows you to define a window to view the objects in an OU (Organizational Unit).
To view the objects in an OU:
1. Browse to the OU you want to enumerate and right-click it.
2. Press New Window from Here.
3. When you want to select the original window, or any other previous window selection, use the Window menu to select 1, or the appropriate Window number.
