JSteimle Posted October 5, 2017 Report post Posted October 5, 2017 Our SCCM installation has been up and going for about a year and a half. We are in the process of reimaging all of our computers for this school year and are now having problems with quite a few machines not PXE booting. We are getting this error on about one third of all machines: PXE-E55 ProxyDHCP service did not reply to request on port 4011 At first I thought it was one model and likely a client machine issue. I reset cmos, ran machine diags, updated bios fiddled with nic settings etc. I also reimaged to the new image via stand alone task sequence media. The machines all have connectivity when booted into windows. The other two thirds of the machines pxe boot and image fine using the same port, cable etc. I have looked in the smspxe log file after attempting to pxe boot a machine that works and one that does not - the entries are the same for both machines. Not sure what to look at next at this point. Jeff Quote Share this post Link to post Share on other sites More sharing options...
