"Access Denied" with encrypted USB device

[stage1v8]

Hi,

I am having some problems with encrypted USB devices. On certain XP SP2
machines when I plug in a usb drive with sopftware encryption on it it comes
up with an Access Denied message if you try and open the drive. It maps the
drive to a drive letter but shows as being 0 Bytes in size.

It does this even if you are logged in as a domain admin.

The frustrating thing is that its only on certain machines. They are all
different hardware and there doesnt seem to be any pattern. If I remove the
encryption software then the drives work fine.

Does anyone have any suggestions?

Thanks

J

Without knowing more about the USB device and the encryption software
used, the only thing that comes to mind is if autoplay is set on or off
on the different machines.

Hi dennis,

Thanks for the reply.

The device is a sandisk cruzer and the encryption is sanctuary from lumension.

Autorun is disabled accross the domain and the PC's "should" be a standard
build.

I have never seen the Access Denied message before. I could understand it
if it poped up that you dont have sufficient privaleges but it does this with
every account I try on the computer.

Its a real puzzler!

Cheers

A lot of these encrypted usb sticks use two driveletters, one for the
software and one for decrypted data.

A possible reason for the trouble is that the decryption software is trying
to create a driveletter which already exists on some computers.

I might also add that they represent a virus risk, requiring as they do that
an uncertified executable has to be run from a modifiable and portable
source. In many ways this is going back to the old 'sneakernet' viruses of
floppy-disk days.
