As I understand SQL Server's Enterprise Manger is an MMC application/snap-in. So just open up Enterprise Manager.
It is most notable when you open a table from EM. In the previous OS version the new window had the menu bar and a tool bar. In XP (at least with our install) it has a windows with no toolbar or menu bar but rather the appropriate toolbar and menu bar are displayed on the parent windows.
I can provide pictures if it will help make more sense.
I would rather have them use Query analyzer but EM is more comfortable for them because they are accustomed to the interface of MS Access that lets them see things kinda like EM. Oh well....old habits are hard to break.
