The control panel's Add/Remove Hardware applet works differently and better under Windows 2000 than it did in previous versions of Windows. Launch it, and you get two options - to add or troubleshoot a device, and to remove or unplug one. Select Add/Troubleshoot a Device, and the wizard scans for new Plug and Play hardware. If it finds none, it will present a list of installed devices (in case you want to troubleshoot). Select Add a New Device, and click Next. The wizard will try to find new hardware, and, if it fails, it will furnish you with a list of hardware categories from which to choose. If you don't find your hardware in the lists that the wizard provides, select Other devices, then Next. Click the Have Disk button, and use the manufacturer's drivers.
If you don't have the manufacturer's disk, download the drivers from the vendor's Web site and point the wizard to the folder in which you saved them.
