- How to Create and Exclusion List for PXE Deployments.
Configuring Distribution Points to Accept PXE Requests:
To deploy operating systems to Configuration Manager Client that make PXE boot request, you must use one or more distribution points that are configured to respond to the PXE boot requests. The distribution point then responds to the PXE boot request and determines the appropriate deployment actions to take.
You can add the distribution point site role to a new system server or add the site role to an existing site system server.
This site can be a primary or secondary site server.
To modify an existing distribution point to accept PXE requests.
1.If there is a risk that critical computer might accidentally PXE boot, create an exclusion list and specify the MAC address of these computers.
2.In the Configuration Manager Console Click -> Administration.
3.In the Administration workspace, expand Overview and Click -> Distribution points.
4.Select the distribution point to configure, and then, on the Home tab in the Properties group, Click -> Properties.
5.On the property page for the distribution point, Click -> PXE tab.
6.To enable this distribution point to respond to the PXE boot requests, select the Enable PXE support for clients
7.To confirm that you want Configuration Manager to use the ports that are required for PXE deployments, the Review Required Ports for PXE -> Yes.
8.To enable Windows Deployment Services so that it responds to PXE service requests, select the Allow this distribution point to respond to incoming PXE requests -> Yes.
Use this check box to enable and disable the service without removing the PXE functionality from the distribution point.
9.To deploy operating system computer that are not managed by
Configuration Manager -> Enable unknown computer support.
10.To provide additional security for your PXE deployments -> required a password when computers use PXE and then specify a strong password.
11.In the User Device Affinity list, specify how you want the distribution point to associate users with the destination computer for PXE deployments.
- Select do not use user’s device affinity to not associated users with the destination computer.
- Select Allow user device affinity with manual approval to wait for approval from an administrative user before users are associated with the destination computer.
- Select Allow user device affinity with automatic approval to automatically associate users with the destination computer without waiting for approval.
12.Specify that the distribution point responds to PXE requests from all network interfaces or from specific network interfaces. If the distribution point responds to specific network interface, you must provide the MAC address for each network interface.
13.Specify, in seconds, how long the delay is for the distribution points before it responds to computer
requests when multiple PXE-enabled distribution points are used. By default, the Configuration Manager PXE service point responds first to network PXE requests.
14.Click OK to update the properties of the distribution point.
How to Create a PXE-enabled Boot Image:
Before you use PXE to deploy an operating system, you must create the boot images to support a PXE deployment. You must have both a PXE-enable boot image and an x64 PXE-enabled boot image that are distributed to one or more PXE-enabled distribution points.
Create boot images for PXE deployments.
1.In the Configuration Manager console -> Software Library.
2.In the Software Library Workspace -> Operating System-> Boot Images.
3.On the Home tab -> Create Group -> Add Boot Image -> Start the Add Boot Image Wizard.
4.On the Data Source -> Specify the following options -> next.
- In the Path box -> Specify the boot image WIM file -> Browse to locate a specific boot image file.
The Specified path must be a valid network path in the UNC format.
For Example: \\servername\<sharename>\bootinage.wim
- Select the boot images that want from the BOOT Image drop-down list. If the WIM file contains multiple boot images, each image is listed.
5.On the General -> Specify the following options-> next.
- In the Name box - > specify a unique name for the boot image.
- In the Version box - >specify a version number for the boot image.
- In the Comment box - > specify a brief description of how the boot image is used.
6.Complete the Wizard.
7.Select the boot image that you just created.
8.On the Home Tab - > Properties Group - > Click Properties - > Select the Data Source Tab.
9.Select the Deploy this boot image from the PXE service point - > OK.
Note: You can now distribute these boot images to any distribution point that accepts PXE requests.
How to Create an Exclusion List for PXE Deployments.
PXE to deploy operating systems, you can create an exclusion list to limit which computer are included in the deployment. The exclusion list contains MAC addresses of the computers that you want distribution point to ignore if these computers send a PXE boot request. These computers do not receive the deployment task sequences that Configuration Manager users for PXE deployment.
How to create the exclusion list.
1.Create a text file on the distribution point that is enabled for PXE.
As an example, name this text file pxeExceptions.txt.
2.Use a standard text editor, such as Notepad, and add the MAC addresses of the computers to be ignored by the PXE – enabled distribution point. Separate the MAC address values by colons, and enter each address on a separate line.
3.Save the text file on the PXE – enabled distribution point site system server. The text file cane be saved to any location on the server.
4.Edit the registry of the PXE - enabled distribution point to create a MACIgnoreLIstFile registry key that contains the string value of the full path to the location of the text file on the PXE – enabled distribution point site system server.
Use the following registry path: HKLM\Software\Microsoft\SMS\DP
