When machines are attempting to PXE boot they are failing with error; **
BOOT SERVER IP: x.x.x.xMFTP...PXE-T00 Undefined error code, or PXE-T01 Undefined error codePXE-E36: Error received from TFTP serverPXE-M0F: Exiting (NIC Manufacturer) PXE ROM.
This is being caused by the PXE Representative attempting to redirect the Client machine to a PXE Rep in another subnet for file download. Currently there are only two solutions;
1) Remove all PXE Representatives except the one you are attempting to use.
2) Disable the Multicast option for the MTFTP service on the PXE Representative.
There is only one supported option for disabling Multicast on the MTFTP server. Disabling Multicast on the MTFTP server will not have a significant effect on the process of imaging machines even if using the Multicast option in the script or template.
Instructions for how to manually disable Multicast (this will need to be performed on all PXE Representatives);
1) On PXE Rep, go to C:\Program Files\LANDesk\PXE\System, double click to run PxeConfig.exe.
2) Right click "Boot Server", then click "Configure Boot Server..", select the "MTFTP Options" tab, and un-check the Multicast option checkbox.
3) Restart both LANDesk PXE services on the PXE Rep and boot into WinPE
