Dell Optiplex 3040 imaging issue

 have recently taken delivery of 150 Dell Optiplex 3040 PC's all with the same specification.

I am trying to image then using MDT.

Before taking delivery of all the PC's I took a sample of 2 to test with to make sure I could create an image and deploy it. This worked without any problem using Litetouch and a defined sequence. Happy days.

I then took delivery of the remaining PC's and tried to apply the same image. However this fails on every PC I have tried apart from the initial 2 samples and it is driving me crazy. PC spec is identical for all PC's and there is only one W10 cab available from Dell that I am using for drivers.

I get a black screen  stating

windows failed to start. A recent hardware or software change might be the cause.

Status Oxc000001

A required device is not connected or can't be accessed.

This happens as the process seems to be connecting to the Litetouch image so I think it might be a possible NIC issue, even though it does successfully connect to the WDS deployment server.

Any suggestions?
