Hi Hangman669
Please try the following...
Download the PXE Forced Mode Utility.
You can find the Tool here (no need to install the tool)
- Remove Option Name: 006 PXE_Discovery_Control
- Remove Option Name: 008 PXE_Boot_Servers
Start the PXE Foced Mode Utility and fill in the IP Adress of your GSS 3.0 Server (see Screenshot)
open the File named DHCPOptionValues.scp using Notepad or any other Editor - you fill find the Value for Option 43.
Add Option 43 to your DHCP Server with the value from the DHCPOptionValues.scp
You can also copy the DHCPOptionSet.bat File and the DHCPOptionValues.scp File to your DHCP Server and start DHCPOptionsSet.bat if you want...
After that try booting to WINPE with a Client and let me know if it works!
Important: Using DHCP Options isn´t up to date because you cannot boot UEFI Hardware and BIOS Hardware with the same Bootfile....(Option 67)
Please take a look at this KB
Using IP Helpers is the recommened method for using mixed Mode Environments (UEFI and Bios HW)
