If you encountered that MDT 2010 Lite Touch or Zero Touch doesn't capture all system settings with USMT, you are not alone....

It's a bug in the ZTIUserState.wsf script...

Update! Microsoft has now released a public fix:

Network drives and network printers are not migrated when you use Microsoft Deployment Toolkit 2010 with the User State Migration Tool (USMT) 4.0
