iPXE Anywhere 2PXE Server
Client PXE Boots normally but then fails during initialization with an “Invalid Password” error and “Password provided cannot decrypt variables file”
The issue appears to be random but consistent. Possibly seen more on Server 2016 2PXE Server
We haven’t actually nailed the root cause but the suspicion is that our process is running ahead of the CM Backend with the added possibility that clock sync may also be causing an issue.
Bouncing the 2Pint service gives a short term solution.
A reliable persistent fix is to edit the 2Pint.2PXE.Service.exe.config file and set:
<add key="CustomVarDataGeneration" value="1"/>
