The following policy is enabled on a Windows Server 2008-based computer or on a Windows Vista SP1-based computer:

System cryptography: Use FIPS compliant algorithms for encryption, hashing and signing

When you open the Failover Cluster Management window on this computer to perform the “Validate a Configuration” task, the validation process fails. Additionally, you receive the following error message:

An error occurred while performing validation. Testing will be cancelled. This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.

In Windows Vista and in Windows Server 2008, the recovery password for Windows BitLocker Drive Encryption is not Federal Information Processing Standards (FIPS)-compliant. Therefore, you may encounter the following issues when the System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing Group Policy setting is enabled.

Issue 1
When you manually add a recovery password at a command prompt, you receive the following error message:

The numerical password was not added. The FIPS Group Policy setting on the computer prevents recovery password creation.

Issue 2
When you try to encrypt a drive on which BitLocker recovery passwords are required, you cannot encrypt the drive as expected. Additionally, you receive the following error message:

Cannot Encrypt Disk. Policy requires a password which is not allowed with the current security policy about use of FIPS algorithms.

Issue 3
When you encrypt a drive, a recovery key is created, but no recovery password is created as a key protector.

Issue 4
A recovery password is not archived in the Active Directory directory service.
