The settings on the PXE Response tab determine which clients Windows Deployment Services responds to, what action is taken when responding to an unknown client, and how long to wait before responding to a client. To view this tab, right-click the server in the MMC-snap in, and then click Properties.

Option Explanation

PXE Response Policy

The following options specify how the Windows Deployment Services server responds to incoming Pre-Boot Execution Environment (PXE) requests from client computers. For more information online, see Prestaging Client Computers (

  • Do not respond to any client computers. Note that this option will only work if Windows Deployment Services and DHCP are running on different servers. This is because although Windows Deployment Services will not respond, DHCP will. You can try to work around this issue by disabling DHCP option 60 on the DHCP Tab.

  • Respond only to known client computers. Choose this option if you have prestaged clients in Active Directory Domain Services. When you select this option, clients that are not prestaged (unknown) will not be able to PXE boot to the Windows Deployment Services server.

  • Respond to all client computers (known and unknown). Choose this option to allow all clients to PXE boot to the Windows Deployment Services server. The check box labeled Require administrator approval for unknown computers is called the Auto-Add policy. Choose this option if you want to approve new clients using the Pending Devices node in the MMC snap-in before allowing them to PXE boot. For more information about this option, see Configure the Auto-Add Policy.

PXE Response Delay

Use this setting to adjust how quickly the server responds to clients on the network. It sets the amount of time that the PXE server waits for other PXE servers to respond. This setting should remain at zero (default) unless there are other PXE responders on the network that have precedence or if your network requires an increased PXE response delay.
