When using Microsoft BitLocker Administration and Monitoring (MBAM) users may receive a Warning message stating, "Computer Record is Rejected" in the application logs on MBAM Server.

When users experience this problem, they will not see the UI prompt on Windows 7 client to start the encryption process.

Also in some cases you may see the UI prompt to Start Encryption Process, but the process will fail and you will see "Encryption Failed" in the UI prompt.

If we open EventViewer on MBAM Server and check Application Logs, you will see the below warning message.

Follow steps below to create a new registry key on MBAM Server where you have MBAM Administration and Monitoring Server role installed.


If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. For information about how to back up, restore, and edit the registry, see Windows registry information for advanced users.

  1. Start Registry Editor.
  2. Navigate to the registry key: HKEY_LOCAL_MACHINE\Software\Microsoft.
  3. On the Edit menu, click New > Key, and add the registry key value: MBAM.
  4. Under the newly created registry key name, on the Edit menu, click New > DWORD (32-bit) Value and name it as DisableMachineVerification.
  5. Set the value to 1.
  6. Exit Registry Editor.

After you make these changes, you must restart the MBAM server for the modifications to take effect.


The above registry key has nothing to do with hardware compatibility checking on the server and hardware compatibility check functionality still works as designed.
