I am receiving the error message PXE-E55: ProxyDHCP service did not reply to request on port 4011 when I attempt to PXE boot to Windows Deployment Services.
WDS is deployed on a server with WSUS and McAfee ePolicy Orchestrator. WDS was originally installed by Windows 2003 Server Service Pack 2 a couple of months ago and has been running fine until a week or so ago.
DHCP is deployed on a separate server in this environment.
The error is intermittent, and only appears to be affecting laptops (HP compaq nx9010 in this instance). The HP desktops are PXE booting okay.
I've attached the XLSM Excel spreadsheet I used in the video and also text files containing the macros used below.
