I have testet BitLocker on Dell E6330 and Dell E7440 and it worked fine. In the Group Policy I have enabled the use of BitLocker without TPM and the recovery key is stored in AD DS.
When I try to activate it on a Dell XPS 13 9343 I get an error stating "TPM on this machine does not work With the current BIOS-Version. Contact the manufacturer to get instructions about how to Upgrade BIOS". (The Message is translated from Norwegian). The machine have the newest BIOS and I have tried to boot the machine with the hdd as the first boot object.
Any idea how to solve this?
Isn't TPM export restricted?
PTT Security were enabled in the BIOS. Disabling it enabled me to start using BitLocker on the machine.
