To date there are two Social MSDN Threads where people and very und-happy and Microsoft DOES not think it’s important
to mention the Problem on their KB Article under Problems. This has just come into our timeline range where
we rollout and MDT/WDS Server for medium sized customer who has no Enterprise Agreement and thus no SCCM.
Manage over 15 WSUS servers for SBS to Enterprise but has no info in that direction. (Not mentioned on MS/TechNet or Ask Woody which we mostly consult for good info)
Problem during PXE Boot:
Windows failed to start a recent hardware or software change might be the cause.
“Status 0xc0000001”

Here is how to fix it:
Uncheck under TFTP the option Enable Variable Window Extension
Reboot the WDS/MDT Server or restart the WDS Service.
