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


Hi all,


Hope you can help here getting the above message when trying to PXE build.

Just a brief outline: = WDS Server + ConfigMgr = DHCP Server


PXE Client on 10.64.67.x subnet.


Now these are Cisco routers with ip helper added to .15 and .16.

I can get an IP address fine but I'm getting the 4011 error.


I couldn't find much articles on how to setup IP Helpers.

Looking at the default list by Cisco ports 69 and 4011 (UDP) used by WDS are not in this list.

Does this mean I have to also add an ip helper port for 69 and 4011?


Help appreciated.
