Installed update 4488598 last week and now our pxe booting is failing. Release notes says that this [Unable to get the DP auth token from MP] issue was resolded on update #4488598, but it actualy appears after this update.
Does anyone knows if there any workarounds for this problem, like tweaking IIS or so or do we just have to wait next sccm update?
Turns out that this was not related to PKi auth or update 4488596.
Some content that tasksequence was using was not replicated to distribution points, even that monitoring content status shows green on all DPs. After redistributing problematic package task sequence runs fine.
