SYMPTOMS
When you attempt to start Windows NT Explorer, your computer may stop responding (hang).



CAUSE
This behavior can occur if you are using a model of the NEC CD-ROM drive that supports SCSI 2 and the Cdaudio service is enabled.



RESOLUTION
To resolve this issue, disable the Cdaudio service. To do this, follow these steps:


 * 1) Click Start, point to Settings, click Control Panel, and then double- click Devices.
 * 2) Click Cdaudio, and then click Startup.
 * 3) Click Disabled, click OK, and then click Close.
 * 4) Restart your computer.



MORE INFORMATION
The Cdaudio.sys driver attempts to detect non SCSI 2 devices at startup. This detection is based on the Inquiry string of the device. Although earlier models of the NEC CD-ROM drives require the Cdaudio.sys driver, newer models of the NEC CD_ROM drives do not require the Cdaudio.sys driver.

Disabling the Cdaudio service on a computer with a model of the NEC CD-ROM drive that supports SCSI 2 does not affect the functionality of the product.
