Hello everyone, I'm currently setting up a WDS server with MDT on Windows. My network uses a pfSense router as the DHCP server. However, when I try to boot a client machine via PXE, I encounter the following errors: PXE-T04: Access violation PXE-E36: Error received from TFTP server Any guidance or suggestions to resolve this would be greatly appreciated. Thanks in advance for your help guys!

Hi guys, I'm having a little trouble with my WDS Server which runs on a Windows Server 2012 R2. I followed this tutorial by BranchCache Bob ( ) to set up DHCP policies in order to get BIOS and UEFI modes to boot up into WDS. The DHCP server runs on the same machine as the WDS server (i.e. I use the DHCP server option 60).First scenario -> PXE boot via BIOS: Works totally fine. Client boots via PXE, receives an ip address, lets me choose a boot image, loads the wim file and initiates the Windows setup. Second scenario -> PXE boot via UEFI: Client boots via PXE, receives an ip address, lets me choose a boot image, loads the wim file and then the screen goes black instead of starting the Windows setup. Nothing happens after that. Only thing I can do is shut down the computer (Ctrl+Alt+Del does not even work) and boot it again. Couldn't find a solution online and hope you guys can help me out with this one! If you need more information just let me know. Thanks in advance. Cheers Marc
