Troubleshoot the MBAM Task Sequence

Sometimes the MBAM Task Sequence will get stuck at the GPUPDATE step, which leaves your computer with an active, owned TPM and no MBAM.

Check for the following.

One: Has the MBAM GPO applied?

Run cmd.exe as an administrator, then run RSOP. Click Close on the resulting Group Policy Error. A Resultant Set of Policy window will open.

Right-click Computer Configuration, then select Properties.

You should see the policy (MD-MBAM-Settings-Only-Policy_prod_1) on the list. Check Display all GPOs and filtering status to see if the policy was Applied or Denied.

Two: Has the MBAM 300MB partition been created, and is it flagged as a system partition?

Run Disk Management (diskmgmt.msc) as an administrator and verify the disk layout.

If the partition is missing, run chkdsk /r on the drive, then re-run the application install (or manually execute "bdehdcfg.exe -target default").

Three: Has the MBAM client been installed?

In Control Panel - Programs and Features, check for MDOP MBAM.
