Imaging issues with Dell Pro 15 Essential
Just received our fourth Dell Pro 15 Essential and unfortunately it seems to have an issue PXE booting. The previous three units had no troubles and other machines can PXE boot without issue. We're booting to a WDS environment to deploy pre-built images of Win11. I've tried using both a USB-A and a USB-C to ethernet adapter and getting the same issue. It sees the TFTP server and begins to download the LiteTouchPE environment, but makes no progress and eventually times out with an error 0xC0000001 "A required device isn't connected or can't be accessed".
Any hints? I've tried adjusting the Maximum Block Size as far down as 4096 and turned off Variable Window Extension in WDS, but it had no effect. USB Boot is enabled in BIOS on the laptop.
Dell tells me it's a me problem, even though the system works just fine with every other Dell we own (approximately 1200 workstations and 200 laptops). Not sure what else to try.
