SYMPTOMS
When you insert a CD-ROM into the CD-ROM drive, it may not be run automatically in Windows.



CAUSE
The Autorun.inf file and the programs it is designed to run may not run when you are logged on to Windows as a user without either Power User or Administrator rights.

By default, only users logged on to Windows with Power User or Administrator rights are allowed to install software. In Windows, files with the .inf extension are considered Setup Information files. As a result, the Autorun.inf file is not initiated if you do not have Power User or Administrator rights.



RESOLUTION
To work around this issue, log on to Windows as either a Power User or Administrator.



MORE INFORMATION
When a CD-ROM is detected, Windows is notified that a new volume is available and the drive is checked for an Autorun.inf file.

In Windows 2000, a user that is not a Power User or Administrator is prompted with an "Install Program as other user" message when the CD-ROM autorun is processed.
