Each new user to logon to Windows 2000 Pro is offered the opportunity to run the Discover Windows 2000 Tour. If you don't want to keep the CD-ROM available, copy the Discover folder from the CD-ROM to %SystemRoot%\Discover.
When a new user logs on, and clicks the Discover link, they get:
Windows 2000 CD Not Found.
Have them click Cancel and Cancel, until the The Discover Tour could not be located. Please indicate the location of the required files dialogue is displayed. They can then Browse to %SystemRoot% , just type %SystemRoot%, and click OK.
If they run Discover again, Windows 2000 will remember.
