How to rename a BitLocker-protected computer without invalidating your recovery key.

If you need to rename a computer that is being protected by BitLocker Drive Encryption, be careful how you do it. If you remove the computer from the domain, rename the computer, and then rejoin it to the domain, the recovery key will be invalidated and won't work any more.

You can use the manage-bde –protectors –adbackup command to store the recovery key in Active Directory. Rename the computer while it is still joined to the domain for the recovery key to remain valid.
