From the Recovery Console you can disable the device driver that is causing the problem but to do this you must know the correct name of the device or driver or both . CHAPTER 11 MANAGING DEVICE DRIVERS 381 SUMMARY Device drivers are software components that enable applications and operating systems to communicate with specific hardware devices. Every hardware device you install in a computer must have a corresponding driver that is designed for use with the operating system the computer is running. Plug and Play is a standard that enables computers to detect and identify hardware devices and then install and configure drivers for those devices. PnP dynamically assigns hardware resources to each device and can reconfigure other devices to accommodate each component s special needs. Windows Server 2003 includes a large library of drivers for many different hardware devices. If Windows does not include a driver for a device in your computer you must obtain one from the hardware manufacturer. The drivers included with Windows Server 2003 are all digitally signed to ensure that they have not been tampered with. You can configure the operating system s behavior when installation of an unsigned driver is attempted by using the Driver Signing Options dialog box. To communicate with the computer hardware devices use .
