When was the last time these machines Scanned?
Are you sure the Bitlocker partition is present, Maybe they were built incorrectly.
The machines scan daily. I am assuming inventory scans you were meaning.
I was under the assumption that if the devices hardware and OS could do bitlocker they would either say fully encrypted or fully decrypted.
yes sorry i meant Inventory. I was checking in case they were just being built and hadn't sent there full scan back since.
I was under the impression that if OS was installed without the Bitlocker partition. ( as i said an incorrect install ) then it would not detect it or report it was encrypted / decrypted.
I am only trying to suggest another avenue, You can rule that out by checking a non reporting machine has the hidden partition used by bitlocker.
I have worked somewhere where Win7 was installed without the hidden partition as they did not use Bitlocker..
