Encryption

Hi All I have a client, that lost his IT administrator, dropped off the face of the earth. I'm now trying to recover data off an encrypted disk. Gigabytes of music collection. The OS is Windows Server 2003, encrypted with, Bestcrypt v2. I have the initial Bestcrypt password, to boot into the OS, but no one knows the Windows login password, therefore can't login into windows, can't see or access the data. I have full access to the machine. What can I use to decrypt the disk, and or salvage the files. I've tried some Live cd's, but that doesn't help. Any suggestions? Thx!!! in advance.

Try ophcrack from here:

20th c./1st half

ophcrack might be able to find the password, but not while the disk is encrypted. Ophcrack won't be able to see the disk. The encryption must be removed first.
