SCCM 2012 PXE-E55: ProxyDHCP service did not reply to request on port 4011

Had this today, didn’t have any of #60, #66 or #67 DHCP options set that might have been conflicting (per Microsoft guidelines).

I was able to build Hyper-V VMs at the site where the problem distribution point was, but PCs weren’t building, giving the error:

PXE-E55: ProxyDHCP service did not reply to request on port 4011

I then checked the SMSPXE.log file which is found on the distribution point on the path D:\SMS_DP$\sms\logs (drive letter might be different, hopefully you’re not using the C drive…)

I saw warnings and messages similar to:

Warning: Matching Processor Architecture Boot Image (0) not found
F8:CA:B8:22:A6:53, 4C4C4544-0051-3610-8030-B3C04F443732: Not serviced.

I checked the two boot images in the SCCM console under Software Library – Overview – Operating Systems – Boot Images. The Boot Image (x64) was distributed to all my DPs, but Boot Image (x86) was missing from the one at the site with the PXE problems.

I distributed the x86 boot image to the distribution point it was missing from, and once that had completed I saw it being picked up in smspxe.log:

Found new image RCM000BF
Opening image file D:\RemoteInstall\SMSImages\RCM000BF\boot.RCM000BF.wim
Found Image file: D:\RemoteInstall\SMSImages\RCM000BF\boot.RCM000BF.wim

PXE boot of the failing clients is now working.
