We have just deployed our SEE Removable Storage and Device control to all users and at the same time we upgraded our SEP clients to 12.1.2. We have some people on our networks/security team that uses TrueCrypt to mount volumes on their computers for encryption so that they can send this information to other people/agencies. The problem is that TrueCrypt will mount the volume that you choose but when you open Windows explorer you cannot open the new drive that TrueCrypt creates. It gives the error Access Denied. The only way to get it to work is to dismount and remount the volume, and I am not sure what difference that makes. I have tested this to see which application is causing it and I still have Device Control and SEP installed on the computer and TrueCrypt works like it should. If I install Removable Storage then it breaks. What on earth could cause this?
