Configuring Administrator Approval

An alternative to pre-staging computers or allowing unrestricted access to Windows Deployment Services images is to require administrator approval before allowing installation. You accomplish this on the PXE Response tab of each server. You can also configure this by setting the PXE Server Initial policy when you install Windows Deployment Services, as described in the section titled "Installing Windows Deployment Services" earlier in this chapter.

To require administrative approval for unknown computers, begin by granting Domain Admin permissions to the computer account of the Windows Deployment Services server. Instructions on how to do this can be found at http://technet.microsoft.com/en-us/library /cc754005.aspx under the heading "Approve a Pending Computer" Then perform the following steps:

1. In the Windows Deployment Services management console, right-click the server and then click Properties.

2. On the PXE Response tab, click Respond To All Client Computers (Known And Unknown) and then select the Require Administrator Approval For Unknown Computers check box, as shown here.

Require administrator approval for unknown computers. When you select this option, you must approve the computers using the Pending Devices node in the snap-in. In addition, a computer account will be created in AD DS for the unknown client.

Systems booted to Windows PE will enter a pending state until an administrator approves their installation. You can view systems in this state in the Pending Devices item of the Windows Deployment Services management console.

Installing Windows 7

For ease of installing Windows 7, client computers must support booting from the network. Windows Deployment Services uses PXE technology to boot from the network and start the Windows Deployment Services client . You must also ensure that the computer's BIOS is configured to boot from the network.

To install Windows 7 from Windows Deployment Services, perform the following steps:

1. Start or reboot the client computer.

2. When the client computer starts and the Windows Deployment Services boot loader prompts you to press F12, press F12 to download and start the Windows Deployment Services client. Make sure you enable network boot in the computer's BIOS .

3. On the Windows Deployment Services page, choose a locale and keyboard layout and then click Next.

4. When prompted to connect to the Windows Deployment Services server, type the user account and password to use for the connection and then click OK .

5. On the Select The Operating System You Want To Install page, choose an operating system image and then click Next.

6. On the Where Do You Want To Install Windows? page, choose a partition on which to install Windows 7 and then click Next. To repartition the disk using advanced options, click Drive Options (Advanced).

7. Windows Setup will install Windows 7, prompting for required settings that are not specified in an unattended-setup answer file.

Capturing Custom Images

Windows Deployment Services can deploy more than just default images from the Windows 7 media You can also create custom boot images and install images and then import them into Windows Deployment Services for automated distribution. Chapter 9 describes how to create custom Windows PE boot images. After creating a custom image, you can import it using the instructions in the section titled "Importing Images" earlier in this chapter.

To create a custom installation image for Windows Deployment Services, you must install an existing image on a reference computer, customize the reference computer as desired by adding drivers and applications, and then capture an image of the reference computer. Image capture is a two-step process . First, you must create a Windows PE capture image to support the image-capture process . Then you capture an image from a reference computer that was prepared for imaging using the Sysprep utility.

To create an image-capture image, perform the following steps:

1. Click the Boot Images item in the Windows Deployment Services console tree.

2. Right-click the image to use as a capture image and then click Create Capture Boot Image .

3. On the Metadata And Location page, type a name and description for the capture image and then specify the location and file name of the image file to create, as shown here. Click Next to create the capture image.

4. Click Finish

5. Import the custom capture boot image by using the instructions in the section titled "Importing Images" earlier in this chapter. Note that Windows Deployment Services in Windows Server 2008 R2 includes a check box on the last page of this wizard that you can select to automatically re-import the image.

To create a custom Windows 7 install image, perform the following steps:

1. Create a master installation by installing a Windows 7 image on a reference computer and then customizing the installation to meet your requirements. You can install Windows 7 on your reference computer either from media or using Windows Deployment Services . To learn how to install Windows 7 using Windows Deployment Services, see the section titled "Installing Windows 7" earlier in this chapter.

2. From a command prompt on the master computer, change directories to \Windows \System32\Sysprep and run the following command.

Sysprep /oobe /generalize /reboot

3. When the reference computer reboots and the Windows Deployment Services boot loader prompts you to press F12, press F12 to download and start the Windows Deployment Services client Make sure you enable network boot in the computer's BIOS

4. In Windows Boot Manager, select the capture boot image

5. On the Windows Deployment Wizard Image Capture Wizard, click Next

6. On the Image Capture Source page, choose the volume to capture from the Volume To Capture list and then provide a name and description for the image Click Next to continue. (Note that if you have omitted step 2, you won't see any volumes available at this point This has been a major area of customer confusion )

7. On the Image Capture Destination page, click Browse to choose the location where you want to store the captured image In the File Name text box, type a name for the image using the .wim extension and then click Save . Click Upload Image To WDS Server, type the name of the Windows Deployment Services server, and click Connect . If prompted for credentials, provide a user name and password for an account with sufficient privileges to connect to the Windows Deployment Services server. Choose the image group in which to store the image from the Image Group list.

8. Click Finish.

NOTE The reason for saving a local copy in step 7 rather than just uploading it to the server immediately is to minimize the chances of corruption occurring over the network.
