MDT failed to load into GUI due to 0xc0000098 iaStorAfs.sys missing or contains error

Dear experts,

I'm having an issue with our MDT server where out of sudden, after completely updating our MDT deployment share, I added the new image into WDS, however, this new image always threw out errors about 0xc0000098 iaStorAfs. I've googled around but didn't find a solution that is applicable to my case.

The one highlighted in red box is the new one I generated and added, you can see its size is abnormal! The other online one which was named with 2021-12-23 is still normal and working, the size of it seems more reasonable. By the way I also used DISM to mount the .wim file and I can see the iaStorAfs.sys is out there in all of the .wim files I added into WDS.

Another odd thing I noticed is that, the new image I added into WDS, it's extremely large size than before, please help to take a check on the screenshots and any advice or recommendation is highly welcome.

Many thanks!

    Dear All,

    This issue has been fixed by put 4096 size for WDS TFTP option and uncheck the TFTP extension, then I deleted my existing WindowsPE .wim which was generated by MDT and resides in DS\Boot\folder, after updating my DS and add the new image into WDS, everything works perfectly!

    Thanks @AllenLiu-MSFT for your time in helping with this case.
