KB4489881 Update Breaks WDS TFTP

[chazzy2501]

I couldn't image new clients today and after fumbling for over an hour with everything from BIOS settings to switch packet sizes, it turns out it was a security update. The KB4489881 went in on the 14th (march 2019) and has now stopped my clients loading the boot installer. The client would get 10% into loading then claim that the resource was unavailable. I've uninstalled this update rollup and WDS works fine again.

Anything I should do?
