SCCM problem with image capture

[neonetman]

I'm going through the process of installing Windows 10 (20H2)

 

* Install from ISO

* make required tweaks

* remove provisioned apps

* Install windows updates

* Run disk cleanup wizard

* reboot

* Mount "wxcapture" iso

* run "launch media"

* Point to UNC path to store image

 

Sysprep then starts, runs for a couple of minutes before failing with a 0x80070070 error.

 

Googling show this is a disk space issue, however there is plenty of space on both the C drive and the UNC path.

 

I can't see anything obvious in the logs in the sysprep/panther directory

 

I'm at a loss where it is running out of space

 

Can anyone help?

I've just found the SMSTS log, and it seems it is trying to write to a Z: drive (I've no idea where that is supposed to be mapped to)
