A new hotfix KB10372804 is released for SCCM version 2103 to address the MBAM BitLocker Issue. Using the MBAM Agent to escrow BitLocker recovery keys generates excessive policies in Configuration Manager 2103.
Invoke-MbamClientDeployment.ps1 PowerShell script utilizes the MBAM Agent API to escrow recovery keys to a Management Point in SCCM 2103. This in turn generates a large amount of policy targeted to all devices, which can cause policy storms.
Note – Install the KB10372804 hotfix only if you are noticing the MBAM BitLocker Issue issues in your setup. To determine that, run the SQL query against each primary site’s database provided in documentation.
SELECT PA.PolicyID, RPM.* FROM PolicyAssignment PA JOIN ResPolicyMap RPM ON PA.PADBID = RPM.PADBID WHERE PA.PolicyID like 'TPM%' AND RPM.MachineID = 0 AND RPM.IsTombstoned = 0
If the above query returns numerous rows, contact Microsoft Support for assistance in removal of these policies.
After installing the hotfix KB10372804, you don’t need to update the client agents or Configuration Manager console. The hotfix includes only site server updates which is mentioned in the hotfix description.
