IT/TECH: Windows Deployment Services (WDS) do not work and fails with "The Following Client failed TFTP" or similar

If you, like I did in the past weeks, find the following or a similar error, the solution maybe far easier than you believe:
The Following Client failed TFTP
Download: Filename: boot\x64\wdsmgfw.efi
ErrorCode: 1460
This error maybe easily resolved. Check whether or not your NICs use Jumbo Frames of whatever size. If so, for this server, specifically, for the NICs responsible for the WDS service, turn Jumbo Frames simply off.

After trying really everything, including re-installation of the whole system, I finally found the one thing I always do (use max. Jumbo Frames) I shouldn't have done with this system.

However @microsoft, the error message is 'missleading' - actually not helping, so much is for sure.
