[sccm 2007] Iastora.sys missing on 64 bit Windows 7

[neonetman]

Good morning all,

 

We've currnetly started migrating to 64 bit Windows 7 (from 32 bit), and have hit a snag with ne group of machines..

 

These machines build fine in 32 bit, however if I try and install the 64 bit build I get an error on OOBE saying IAstorA.sys is missing.

 

I've got the driver pack installed, and have tried with and without auto-apply drivers with no success

 

I'm beating my head on this one so hoping for some help on here

 

Cheers all
