Configuring Server Hardware Devices

• Hardware devices can include the following:– Disk drives– Disk controllers– Network adapters– CD/DVD drives– Keyboard– Pointing devices– Monitor

Configuring Server Hardware Devices

• Sometimes Windows doesn’t recognize a piece of hardware and you want to make the hardware work before you install any applications

• Device Manager and the Add Hardware Wizard can help install support for devices that Windows doesn’t recognize by default

Configuring Server Hardware Devices

• In many cases, Windows Server 2008 won’t install a driver, even when one exists, because the vendor hasn’t signed the driver. You can override this behavior on 32-bit systems to get the piece of hardware up and running.– When a driver is verified, a unique digital signature is

incorporated into it– When Windows Server 2008 determines that a device

driver is not signed, it gives you a warning• Device drivers that are unsigned cannot be loaded in x64

versions of Windows Server 2008

Plug and Play

• Plug and Play (PnP)– The ability to automatically detect and configure

newly installed hardware devices• For this capability to work, PnP must be:– Built into the device– Built into the computer operating system kernel

• PnP eliminates hours of time that server administrators and computer users once spent installing and configuring hardware

Using Control Panel and the Add Hardware Wizard

• For windows to detect a new device:– Automatically detect the new device by PnP– Use the vendor CD or DVD– If the vendor doesn’t provide a CD or DVD the

user must use the add hardware wizard from the control panel

Using Control Panel and the Add Hardware Wizard

• The Add Hardware Wizard is used for the following tasks:– Invoke the operating system to use PnP to detect

new hardware– Install new non-PnP hardware and hardware drivers– Troubleshoot problems you might be having with

existing hardware• The Add Hardware Wizard is started from

Control Panel

Using Device manager

• Device Manager– Used to check for a resource conflict and to examine

other properties associated with a device– Provides a graphical view of all hardware currently

installed on your computer– Can also be used to:

• Verify if hardware installed is working properly• Update device drivers• Disable a device• Uninstall a device• Configure the settings for a device

Using Device manager

• You can access Device Manager– Right-click Computer and choose Properties from the

context menu.– Click Device Manager in the Tasks area.– OR. From the control panel

• Viewing broken devices:– A small yellow triangle containing an exclamation mark

next to the device indicates that the device isn’t functioning

– Whenever you open Device Manager, it shows you all broken devices automatically, by expanding the hierarchy to show these devices and displaying the little yellow icon

Fix a broken device• The method you use to fix a broken device

depends on the problem it has.• Fortunately, Device Manager normally provides

some kind of clue to the problem. To see this clue, right-click the device entry and choose Properties from the context menu. Select the General tab and you see a Properties dialog box, , such as the one in the following figure, In this case, you can usually fix the problem by clicking Reinstall Driver. Device Manager shows you the Update Driver Software Wizard

Fix a broken device

• Sometimes a device won’t even appear on the list. You installed it, but Windows simply doesn’t recognize it. When this problem occurs, make sure to verify that you installed the device correctly. A missed connector or a connector that isn’t firmly seated can cause all kinds of problems. If you’re certain that the device is installed correctly, choose Actions Scan for Hardware ➪Changes, and Windows checks for the new device. OR uninstall the device and re-install it again
