Hello,
I have an MDT-integrated task sequence deploying Windows 8.1 in the Refresh scenario to Windows 8.1 machines with MBAM-managed BitLocker, set to require a PIN.
The problem I'm having is when I run the task sequence, I am prompted to enter the BitLocker PIN immediately after the first reboot that occurs after the ConfigMgr client is installed.
I have added a task immediately before the reboot action which runs c:\windows\system32\windowspowershell\v1.0\powershell.exe suspend-bitlocker -rebootcount 10 -MountPoint "C:".The built in task to disable BitLocker also runs and completes successfully towards the beginning of the task sequence. The client settings package deployed to all workstations has the setting "Suspend BitLocker PIN entry on restart" set to Always. I've also tried removing the MBAM client before running the Refresh.
Any idea what could be causing the PIN prompt?
