ukg_matt Posted January 23, 2020 Report post Posted January 23, 2020 I’ve been following the Bitlocker management tutorial here. Apart from the previous MBAM Install error over here, everything has gone as expected, apart from actual device encryption….. I’ve configured everything as per the tutorial, I have a set of devices, I have the configuration base line to deploy the reg keys to force encryption to start, I’ve configured and deployed the policy to the machines. The clients have the MDOP client. If I run “(Get-WmiObject -Class mbam_Volume -Namespace root\microsoft\mbam).ReasonsForNoncompliance” on any of the clients, I get the 3 codes returned, 1, 16 and 3. From here the error codes are as follows : 1 MBAM Policy requires this volume to be encrypted but it is not. 3 MBAM Policy requires this volume use a TPM protector, but it does not. 6 Policy requires minimum cypher strength is XTS-AES-256 bit, actual cypher strength is weaker than that. The policy I configured in SCCM is XTS-AES-256, do I need to do something else? Configure a GPO maybe? I wasn’t sure exactly what other detail to include so feel free to ask me for some logs etc. Quote Share this post Link to post Share on other sites More sharing options...
anyweb Posted January 23, 2020 Report post Posted January 23, 2020 no GPO's needed, can you attach (or email me) the 2 bitlocker related logs in c:\windows\ccm\logs and can you do a teamviewer session so i can take a look ?

APd Posted February 6, 2020 Report post Posted February 6, 2020 Did you work this out? We've been encrypting with MBAM for a while now successfully, now we're having a rash of computers not encrypting because "actual cypher strength is weaker" and it's not clear what has changed.

Carl Davis Posted February 11, 2020 Report post Posted February 11, 2020 Hi Niall, I have used your guides to implement SCCM MBAM 1910 and it went in successfully. I am however facing an issue where the clients - even though they receive the policies and the registry change to encrypt without user action - I find that nothing happen until I manually run MBAMClientUI.exe. I've even changed the MBAM Registry to implement "NoStartupDelay" and no joy. I've had one or two successful when the MDOP client pops up but the rest just sit there. Any advice is greatly appreciated and I look forward to hearing from you Regards Carl Davis P.S - AMAZING GUIDES BTW - Thank you for taking the time to write and video , 1 Quote Share this post Link to post Share on other sites More sharing options...

My problems was/is that the SCCM Bitlocker policy could not be enforced... What do the event logs say on both server and clients?
