I had a Windows To Go stick with McAfee agent 5.04 and MNE 4.1. I booted to the USB stick, logged into Bitlocker with the PIN, logged into Windows, installed Windows Updates and shut it down.
The next morning I booted up the stick and it was asking for USB device with recovery key or Bitlocker recovery instead of asking for the PIN.
I logged into ePO and found the system and now it shows as "unmanaged" with no way to get a Bitlocker recovery key,
How can this happen and how can I prevent it from happening again?
