We've been using a FOG server and Microsoft DHCP server to hand out DHCP addresses and pxe boot for imaging purposes. This has worked flawlessly for the better part of a year now and many thousands of images/re-images. Suddenly last week it quit working.
In my discovery this is what I've found: If I remove all of the bootprelay ip definitions from my switches pxe works perfectly, but of course my devices out on various vlans no longer get an address assigned via the DHCP server. As soon as I add them back in the problem immediately comes back and I can't pxe any more. Does anyone have any info that may help? I've been through the forums and can't seem to find anything that resolves this.
Any help is greatly appreciated.
