Verify Your ConfigMgr Distribution Points are PXE-enabled

Before you can use the Pre-Boot Execution Environment (PXE) in your environment, you need to ensure at least one of your Configuration Manager distribution points (DPs) has been configured to support PXE deployments.

To verify that your ConfigMgr DPs are PXE enabled:

  1. Start the Configuration Manager Console
  2. Click the Administration workspace.


  1. Navigate to Overview | Distribution Points


  1. Scroll across to the right until you find the PXE column which will tell you whether the DP has been enabled for PXE or not.


  1. If no DP has been enabled to support PXE deployment yet, double-click the relevant DP you wish to enable.

  1. On the <dp_name> Properties screen, click the PXE tab.


  1. Check the Enable PXE support for clients checkbox which will pop up the Review Required Ports for PXE dialog box. Click Yes on the Review Required Ports for PXE message box which lists the ports used by PXE.
InformationAs per the message, if you have enabled the Windows Firewall on this server, by clicking Yes you are allowing ConfigMgr to automatically modify the firewall rules to allow the ports listed. If you are using a different firewall, you will need to configure it accordingly to allow PXE to work.

Also, if you are running Windows Deployment Services (WDS) and Dynamic Host Configuration Protocol (DHCP) on the same server, as DHCP and WDS listen on the same port, you have to configure WDS to listen on a different port. For more information, see the "Considerations when you have WDS and DHCP on the same server" in the Microsoft ConfigMgr Documentation Library. 

  1. Check the Allow this distribution point to respond to incoming PXE requests checkbox and optionally the Enable unknown computer support checkbox to be able to deploy operating systems to computers not managed by ConfigMgr. Checking this checkbox will pop up the Configuration Manager message box warning of the potential outcomes of enabling unknown computer support. Click OK on the Configuration Manager message box to close it.
InformationYou do not have to check the Enable unknown computer support checkbox as you can pre-stage computers in ConfigMgr for use with PXE using either the ConfigMgr Console or the Control Center. 

  1. If you want to require a password to be entered for computers that are PXE booted (to prevent a computer being inadvertently rebuilt/wiped if it’s PXE-booted), enter a strong password in the Password and Confirm password fields. If you don’t want to password protect the use of PXE, clear the Require a password when computers use PXE checkbox.

  1. Select how you want to handle User Device Affinity (UDA) relationships from the User device affinity dropdown list.

  1. Click OK

Once PXE has been enabled on the DP, the PXE column will state Yes

  1. Repeat this process for any other DPs in your environment you want to enable for PXE.
InformationLeave the ConfigMgr console open as it is required in the next section. 

Now you have verified your ConfigMgr DPs are PXE-enabled, the next stage of the process is to create a ConfigMgr Boot Image for Commence.
