My experimental environment

VMWARE, client and server use VMware 8 (Nat) network, shut down the use of local DHCP services


Server win-2008: DHCP (, DNS (www.feiquan.net), WDS server, domain is feiquan.com (

After the client is configured, start from PXE: prompt error: ProxyDhcp service did not reply to request on port 4011



  If Windows Deployment Services and DHCP are running on the same computer, configuring Windows Deployment Services to not respond to any client computers will not work. 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

   The main problem is DHCP configuration error. To add 60,67 boot x64 wdsnbp.com, because my DHCP is the same computer as the WDS server, and then restart the WDS server.

Server side:

DHCP Server Configuration

DNS Server:

WDS Server:


If the above DHCP has been modified after 60,67, restart the WDS server, DHCP server. In this way, the client will request recognition again. If you do not reboot, you will always be prompted for the above errors even after you modify the configuration. I restarted the computer directly to solve the problem.
