We are currently testing Bit Locker in our domain environment as a possible complete drive encryption solution. We have an Access program that currently checks for a third-party drive encryption before they are allowed to open it. The administrator for this Access program wants to have it check for the BDESVC in our test group before they are allowed to open it. I have enabled Bit Locker on two computers that are running Vista Enterprise SP2. Bit Locker is enabled on the drive, TPM's are enabled and activated, the users are prompted for their PIN on startup, the recovery password is backed up to AD, and I can see that Bit Locker is functioning in Control Panel. Here's where it gets weird. The BDESVC is missing from the Services snap-in. I have checked C:\Windows\System32 and the only item I see there pertaining to Bit Locker is BitLockerWizard.exe. There are no other files there that apply to Bit Locker. The bdesvc.dll file is missing, along with everything else that should be present that controls Bit Locker. I even checked in the Bit Locker partition to see if those files had been moved there for some reason, and they had not. Any ideas what might have happened to these files? Is there a workaround to fix this without having to completely decrypt the drive and starting from scratch? Is there some setting in Group Policy that might have completely hidden these files, even from the local administrator account? Any and all help in this area would be greatly appreciated!!!
