Registry filter limitation

Hi

I need to use registry filter over my EWF image to be able to preserve the
domain security key. I've been testing this feature for a while now with EWF
RAM, EWF, Disk and FBWF. Everything works like a charm except in EWF disk
mode. For some reason, the Registry filter does not apply the Specified
registry setting to the disk when EWF is set to disk mode.

I looked on MSDN and news group and it is not specified anywhere that
regfilter is not compatible with EWF Disk mode. I did not find either any
example of regfilter EWF disk usage... The target designer registry filter
component help resume the fonctionnality and state athat is is applicaple to
EWF and FBWF is whatever setup we use it...

I'd like to have some feedback on this as we want to use the EWF disk
solution with regfilter to cover our needs.

Thanks in advance
 
Something is missing since Registry Filter is not compatible with EWF Disk
mode. Registry Filter is needed to help preserve registry keys between boots
for RAM overlays. This is because data stored in the RAM overlay is lost
between boots. EWF Disk mode preserves data between boots so the Registry
Filter is not needed.

Hi Sean

Thanks for the fast response.

This is what I expected... The reason why we wanted to have the regfilter
component working with the disk overlay is that we have a possible huge
quantity of data to protect against currruption. We curently have a scheme
where our disk overlay get overwritten at every boot, so it act like a RAM
overlay, but with lot more space. The only problem with that is the
domain/TSCAL security key.

I'll figure out something else

Thanks

Why not do what we do... partition the drive and put the registry filter image
on a non-EWF disk? Works great... It's not like the partition would have to
be very big at all.
