I am having the hardest time with this error.
My environment is all Server 2016 (Vmware 6.7)
MDT 8456
ADK and WinPE - 17763.1 (1903)
Regardless of what option i go with. EFI, BIOS, x86,x64 (Nic VMXnet, e1000, e1000e). WDS Set TFTP Max size to 0,512,1024,2048 up to max, or disabling Variable Window Extension I cannot get the TFTP downnload to complete. DHCP hands out an IP, PXE response is there, it gets the boot file and starts the download of the WIM but almost always fails. I can throw out 30 VM's and maybe 2 or 3 will get all the way to the WINPE environment. Doesnt *seem to present the issue in a physical workstation (But I cant roll the quantity like i can in a virtual environment to test). All the rest will fail with the error I have in the Title.
WDS server shows the Error code 1460
Followed all the links and NOTHING is helping me.
Alot of people talking about the March Update from this year causing this, but I'm on CU for the month so unless it was re-introduced I'm not sure what the cause is. This environment has been working for over a year.
I've cleared my entire DHCP reservations so there are no duplicates or anything of that nature.
I've tried completely removing WDS and the share and then re-installing/configuring and regenerating Boot files.
No Dice.
