BitLocker and Key Escrow

Hi All,

I'm trying to set up BitLocker with key escrow. The Domain Controller is a fresh Longhorn (5600) installation. I turned on key escrow on the client.

But when I try to turn on BitLocker, I get the message that AD doesn't have the required attributes and classes to host BitLocker or TPM. I tried to use the ADPrep on the Vista DVD, but it said the attributes already existed.

One other thing. The TPM on this box doesn't work, so I'm using the USB key option.

Thanks in advance!
