Are you using option 66 and 67 together? What did you fill in in option 67? Have you filled in this in option 67 SMSBoot\x64\wdsnbp.com In option 66 should be the IP of the SCCM server

yes the two options together and the 67 SMSBoot\x86\wdsnbp.com, and the 66 the ip of the sccm server – Ragnar Mar 12 '15 at 09:56

Do you receive an IP? At PXE boot – Saeed Mar 12 '15 at 14:04

some other points: * Are the boot images distributed? * Do they have network drivers? – Saeed Mar 12 '15 at 14:23

yes the client receives ip from dhcp and the boot images distributed but i didn't inject the boot images with network driver – Ragnar Mar 12 '15 at 17:03

So, did it work? After injecting the drivers? I would recommend just injecting universal Intel (if it is intel based) network drivers. Make sure you clear the PXE deployments of that group in assets before you deploy again. – Saeed Mar 13 '15 at 07:45

no it didn't work i can't see why its not working i made a boot media and everything worked correctly but over the network its not working – Ragnar Mar 15 '15 at 11:49

Did you create your own boot images of that of sccm? Try adding the boot images again and changing the properties as you like and than distributing them again. I have had this before and solved it like this. This is a good way to do it http://www.niallbrady.com/2013/10/09/how-can-i-manually-add-winpe-5-boot-images-to-system-center-2012-configuration-manager-sp1-cu3/ – Saeed Mar 15 '15 at 16:43

Any suggestion on modifying the cisco dhcp configuration – Ragnar Mar 18 '15 at 11:00

thank you all i solved the issue actually two weeks ago by configuring only the 1- next server option the sccm fqdn or the IP 2- the boot file option smsboot\x86\pxeboot.com
and allow the traffic between the sccm server and the client machines throw fortigate firewall
thanks

In my case, WDS Service was stopped after an upgrade. Just check if all required services are started after an upgrade
