Hi all -

Though I've read through every related article on the subject I still find myself in a bind.  Bottle of virtual champagne for anyone who can assist.

We're running SCCM 2012 and have a distribution point configured.  It sits on one subnet while our DHCP sits on another.  I have IPhelpers configure to forward DHCP requests to both the DHCP server AND the WDS.  I also have options configured in DHCP to point to the deployment server which you can see in the trace.  The machine gets the correct info which you can also see in the trace.

Never the less, the PXE client fails to make the connection and errors out with the dreaded "proxyDHCP failed to respond on port 4011" message.

I'm at a loss.  I don't know how to proceed with troubleshooting as I am out of ideas.

Firewalls, both physical and software, are not the issue as everything is open.

Can someone nudge me in the right direction?
