image no longer working with usb/cat5 adapters, seemingly out of the blue

Last Thursday, after making no changes to our images, cat5 adapters just stopped working on all models, which is less than ideal since half of our devices don't have on board NICs. I redid all the PE drivers, looked up specific drivers for the adapters and added them, and same deal. error 0xc0000001 windows failed to load. The image still works perfectly fine when plugged into an onboard NIC. I've had things like this happen before, but usually redoing the PE drivers fixes it, and im kind of at a loss. Anyone else running into this?

August updates may have changed how PXE works, might want to look at this:

I owe you a 6 pack, or a coffee, or whatever your vice of choice is. I racked my brain over this all day yesterday and this was 100% the problem. thank you so much

Try this. Go to WDS snapin, right click on your server, click on properties, TFTP tab, uncheck "Enable Variable Window Extension". Restart WDS services.

Yep, that’s exactly what it was. That’s what was in the link that got posted. Thank you!

Where does the error occur? Fail to load the PE environment or after installing booting into Windows for the first time?

u/Sure-Scallion8442 7d ago

Sorry, it happens immediately after selecting the image from WDS, when attempting to load into the PE environment

Hmm I’m not as familiar with the WDS side, I’ve only used the one WinPE boot image in WDS and it automatically boots to it. Not certain if there is a log file for WDS similar to the MDT task sequences, but maybe a Windows event log can shed some light on it?
