That should not be a problem when the client and the servers are on the same network. But what if the client and servers are on different networks? The answer is in the configuration of the routers. They need to be able to route the client requests from the network of the client to the network of the DHCP server.
One such simple router rule is the " ip helper. But what about the PXE requests? There is no other skill to learn. It is the same thing that you already know how to do and that you have already done. This time, you just need to do it for another server, the PXE server.
Even though there is a very, very simple solution, you will see administrators using an alternative route. It will also respond to the client with path to the network boot program Option The DHCP server can fool most client firmware in this manner, but not all. Some firmware are too trusting. When it is time to download the boot files, it will try to download them from the DHCP server. This will of course fail - the DHCP server does not have any boot files.
The granddaddy of the problem - whatever you put in the DHCP option especially option 67, the boot program path , that is it. What if you have different types of machines that want to PXE boot?
You see, there are different network boot programs depending on the client architecture and firmware mode. Many admins find this out the hard way. BIOS clients work because they specified wdsnbp. Not only are the file names different, the folders are also different depending on the PXE server. For example, in WDS, the folder is 'Boot. You could program your DHCP server. Add logic there to detect the client architecture and firmware. The filters you created for your dhcp server should match what the client says it is.
This is the client telling the dhcp server, hey I'm a 7 uefi bc. The next packet comes from the dhcp server and its an Offer. In the dhcp options in the packet you should also have dhcp options 66 and 67 that mirror next server and boot file respectively. Prior to doing this I've been able to see computer recognize the PXE Server, get IP, go through the loading bar, and then it flashes the Microsoft Windows flag icon in the middle of the screen.
After that screen goes blank. Ok so as far as you discussed PXE booting is working and not your problem here. The windows logo is being displayed by the windows boot loader. So if the boot loader is displaying the logo then PXE has handed off control to the boot loader wdsmgfw. PXE booting has done its job.
Your issue is now beyond pxe booting and in the WDS land. I don't use WDS so I can't help with the setup. You will need to know what firmware type your target computer is and then dig into the wds setup for that firmware. Whoops sorry got my threads mixed up.
