When using Modern Standby devices such as Surface devices , the -forcerecovery option is not recommended because BitLocker will have to be unlocked and disabled manually from the WinRE environment before the OS can boot up again. For more information, see BitLocker Troubleshooting: Continuous reboot loop with BitLocker recovery on a slate device.
When planning the BitLocker recovery process, first consult your organization's current best practices for recovering sensitive information. For example: How does your enterprise handle lost Windows passwords? How does your organization perform smart card PIN resets? You can use these best practices and related resources people and tools to help formulate a BitLocker recovery model. MBAM makes BitLocker implementations easier to deploy and manage and allows administrators to provision and monitor encryption for operating system and fixed drives.
MBAM prompts the user before encrypting fixed drives. MBAM also manages recovery keys for fixed and removable drives, making recovery easier to manage. After a BitLocker recovery has been initiated, users can use a recovery password to unlock access to encrypted data.
Consider both self-recovery and recovery password retrieval methods for your organization. Determine a series of steps for post-recovery, including analyzing why the recovery occurred and resetting the recovery password.
In some cases, users might have the recovery password in a printout or a USB flash drive and can perform self-recovery. We recommend that your organization create a policy for self-recovery. If self-recovery includes using a password or recovery key stored on a USB flash drive, the users should be warned not to store the USB flash drive in the same place as the PC, especially during travel, for example if both the PC and the recovery items are in the same bag, then it's easy for an unauthorized user to access the PC.
Another policy to consider is having users contact the Helpdesk before or after performing self-recovery so that the root cause can be identified. If the user does not have a recovery password in a printout or on a USB flash drive, the user will need to be able to retrieve the recovery password from an online source.
However, this does not happen by default. The following policy settings define the recovery methods that can be used to restore access to a BitLocker-protected drive if an authentication method fails or is unable to be used.
Select the Do not enable BitLocker until recovery information is stored in AD DS check box if you want to prevent users from enabling BitLocker unless the computer is connected to the domain and the backup of BitLocker recovery information for the drive to AD DS succeeds.
If the PCs are part of a workgroup, users should be advised to save their BitLocker recovery password with their Microsoft Account online. Having an online copy of your BitLocker recovery password is recommended to help ensure that you do not lose access to your data in the event that recovery is required. You can use the following list as a template for creating your own recovery process for recovery password retrieval.
You can use the name of the user's computer to locate the recovery password in AD DS. If the user does not know the name of the computer, ask the user to read the first word of the Drive Label in the BitLocker Drive Encryption Password Entry user interface.
This is the computer name when BitLocker was enabled and is probably the current name of the computer. Verify that the person that is asking for the recovery password is truly the authorized user of that computer. You might also want to verify that the computer with the name the user provided belongs to the user.
Because Computer object names are listed in the AD DS global catalog, you should be able to locate the object even if you have a multi-domain forest. If multiple recovery passwords are stored under a computer object in AD DS, the name of the BitLocker recovery information object includes the date that the password was created. If at any time you are unsure what password to provide, or if you think you might be providing the incorrect password, ask the user to read the eight character password ID that is displayed in the recovery console.
Since the password ID is a unique value that is associated with each recovery password stored in AD DS, running a query using this ID will find the correct password to unlock the encrypted volume.
Before you give the user the recovery password, you should gather any information that will help determine why the recovery was needed, in order to analyze the root cause during the post-recovery analysis.
For more info about post-recovery analysis, see Post-recovery analysis. Because the recovery password is 48 digits long, the user might need to record the password by writing it down or typing it on a different computer. If you are using MBAM, the recovery password will be regenerated after it is recovered from the MBAM database to avoid the security risks associated with an uncontrolled password.
Because the digit recovery password is long and contains a combination of digits, the user might mishear or mistype the password. The boot-time recovery console uses built-in checksum numbers to detect input errors in each 6-digit block of the digit recovery password, and offers the user the opportunity to correct such errors.
When a volume is unlocked using a recovery password, an event is written to the event log and the platform validation measurements are reset in the TPM to match the current configuration. Unlocking the volume means that the encryption key has been released and is ready for on-the-fly encryption when data is written to the volume, and on-the-fly decryption when data is read from the volume.
After the volume is unlocked, BitLocker behaves the same way, regardless of how the access was granted. If you notice that a computer is having repeated recovery password unlocks, you might want to have an administrator perform post-recovery analysis to determine the root cause of the recovery and refresh BitLocker platform validation so that the user no longer needs to enter a recovery password each time that the computer starts up.
If a user needed to recover the drive, it is important to determine the root cause that initiated the recovery as soon as possible. Properly analyzing the state of the computer and detecting tampering may reveal threats that have broader implications for enterprise security.
While an administrator can remotely investigate the cause of recovery in some cases, the end user might need to bring the computer that contains the recovered drive on site to analyze the root cause further. To help you answer these questions, use the BitLocker command-line tool to view the current configuration and protection mode for example, manage-bde -status.
Scan the event log to find events that help indicate why recovery was initiated for example, if the boot file changed.
Both of these capabilities can be performed remotely. After you have identified what caused recovery, you can reset BitLocker protection and avoid recovery on every startup.
The details of this reset can vary according to the root cause of the recovery. If you cannot determine the root cause, or if malicious software or a rootkit might have infected the computer, Helpdesk should apply best-practice virus policies to react appropriately.
If a user has forgotten the PIN, you must reset the PIN while you are logged on to the computer in order to prevent BitLocker from initiating recovery each time the computer is restarted.
If you have lost the USB flash drive that contains the startup key, then you must unlock the drive by using the recovery key and then create a new startup key. This error might occur if you updated the firmware. As a best practice, you should suspend BitLocker before making changes to the firmware and then resume protection after the update has completed. This action prevents the computer from going into recovery mode. However if changes were made when BitLocker protection was on, then log on to the computer using the recovery password, and the platform validation profile will be updated so that recovery will not occur the next time.
If a PC is unable to boot after two failures, Startup Repair will automatically start. When Startup Repair is launched automatically due to boot failures, it will only execute operating system and driver file repairs, provided that the boot logs or any available crash dump point to a specific corrupted file.
In Windows 8. If the Windows RE environment has been modified, for example the TPM has been disabled, the drives will stay locked until the BitLocker recovery key is provided. If Startup Repair can't run automatically from the PC and instead Windows RE is manually started from a repair disk, then the BitLocker recovery key must be provided to unlock the BitLocker—protected drives.
During BitLocker recovery, Windows can display a custom recovery message and hints that identify where a key can be retrieved from.
These improvements can help a user during BitLocker recovery. BitLocker Group Policy settings in Windows 10, version , let you configure a custom recovery message and URL on the BitLocker recovery screen, which can include the address of the BitLocker self-service recovery portal, the IT internal website, or a phone number for support. BitLocker metadata has been enhanced in Windows 10, version to include information about when and where the BitLocker recovery key was backed up.
It is used solely by the BitLocker recovery screen in the form of hints to help a user locate a volume's recovery key. Hints are displayed on the recovery screen and refer to the location where the key has been saved. Hints are displayed on both the modern blue and legacy black recovery screen. This applies to both the boot manager recovery screen and the WinRE unlock screen. We don't recommend printing recovery keys or saving them to a file. Instead, use Active Directory backup or a cloud-based backup.
Result: Only the hint for a successfully backed up key is displayed, even if it isn't the most recent key. Besides the digit BitLocker recovery password, other types of recovery information are stored in Active Directory. This section describes how this additional information can be used. If the recovery methods discussed earlier in this document do not unlock the volume, you can use the BitLocker Repair tool to decrypt the volume at the block level.
Cannot connect to the domain controller. You must be logged in as a domain user with a connection to the network. The computer is not connected to the network, or the computer cannot communicate with the domain. You do not have permissions to perform this install. Enterprise administrative rights are required.
You may receive this error message when you try to install the first instance of the BitLocker Recovery Password Viewer tool in a forest.
Also, you must have Read and Write permissions to the parent containers of these objects in the Active Directory configuration database. By default, members of the Enterprise Administrators group have Read and Write permissions to these objects. Error message 5. You may receive this error message when you try to perform a second or later installation of the BitLocker Recovery Password Viewer tool in a domain.
Also, you must have at least Read permissions to the parent containers of these objects in the Active Directory configuration database. Click Start , click Run , type appwiz. In the Add or Remove Programs dialog box, click to select the Show updates check box. If you receive a message that states that other programs may not run correctly if you remove this update, click Yes to confirm the removal of this update.
Note The removal of the BitLocker Recovery Password Viewer tool does not prevent other programs from running correctly. In Active Directory Users and Computers, locate and then click the container in which the computer is located.
For example, click the Computers container. For more information about how to locate a computer account, visit the following Microsoft Web site:. In the ComputerName Properties dialog box, click the BitLocker Recovery tab to view the BitLocker recovery passwords that are associated with the particular computer.
Follow the steps in the "To view the recovery passwords for a computer" section to view the BitLocker recovery passwords. In the Find BitLocker Recovery Password dialog box, type the first eight characters of the recovery password in the Password ID first 8 characters box, and then click Search.
A2: No. To view recovery passwords, you must be a domain administrator, or you must have been delegated permissions by a domain administrator. If a user who does not have sufficient rights installs the BitLocker Recovery Password Viewer tool, that user cannot locate any recovery passwords for any computer. Also, if you use the BitLocker Recovery Password Viewer tool to search for recovery passwords among all the domains in a forest, results are returned only from the domains in which you have sufficient rights.
Note The BitLocker Recovery Password Viewer tool cannot distinguish between a situation in which no recovery passwords exist for a particular computer and a situation in which you do not have sufficient rights to view the recovery password for a particular computer. Q3: What if a stored recovery password does not appear on the "BitLocker Recovery" tab of a computer's " ComputerName Properties" dialog box? A3: Usually, the BitLocker recovery passwords for a particular computer appear on the BitLocker Recovery tab of the ComputerName Properties dialog box for that computer.
However, if a computer is renamed, you may be unable to locate the correct computer. This is because the drive label information still contains the original computer name. In this situation, you must use the password ID information to search for the recovery password.
Q4: Why are only the first eight characters of the password ID used to search for the location of a recovery password? A4: This is a design decision that is intended to help simplify searching for recovery passwords without sacrificing the accuracy of the search operation. Tests that randomly generated over one million password IDs typically yielded only duplicates for the first eight characters of the password ID.
Therefore, even if you have one million recovery passwords in a search domain, it is unlikely that two recovery passwords will be returned by a single search operation. Additionally, it is even more unlikely that more than two recovery passwords will be returned in the same search. Note We recommend that you examine the returned recovery password to make sure that it matches the whole password ID that you used to perform the search.
This is to verify that you have obtained the unique recovery password. Q5: How long does it take to search for a recovery password across all domains? A5: Generally, it takes no more than several seconds to search for a password ID across all the domains of a forest. However, you may experience decreased performance if the following conditions are true:. A6: Use the following information to help troubleshoot issues that you experience when you use the BitLocker Recovery Password Viewer tool:.
