Hi.

We're running MEM 2010

When trying to build some machines at a site, we're continuously running into the error attached .

133539-wds-pxe-error-01.png

As per some solutions advised we've tried to change the TFTP block size and also disabled the Variable Window Expansion option (steps below)

  1. Open the WDS console, right click on the server then click on Properties
  2. Go to the TFTP tab, block size enter 4096 or more
  3. Uncheck Enable Variable Window Expansion and click Apply
  4. Restart WDS service

But we've not seen any change. We're not configuring WDS anywhere specifically, but instead it's being controlled by SCCM. Next option, we're considering is to find if there's any DHCP Snooping that's happening and then to disable the same.

Kindly advise if anything else can be done.

    Hi, @SAMUEL VALAPARLA
    Thank you for posting in Microsoft Q&A forum.

    Error 0xC0000001 is related to some problem/conflict between TFTP and the network adapter of the machine you're imaging, here are some link in below article that you may try, such as:
    Update send and receive buffers
    Update the registry key of "RamDiskTFTPBlockSize" from 16384 to 1456
    reinstall WDS

    And if the issue occurs on a specific model of computer, you may need to add the network adapter driver to the boot image.
