Hello all, I've created Task Sequence, which contains 3 steps. 1. General/Install software (Runs program, which start HP BiosConfigUtilty to enable TPM chip) 2. General/Restart computer 3. Disks/Enable Bitlocker (TPM only, store Recovery Keys to Active Directory) When assigning my Task Sequence to Win7 64-bit computer which is directly connected to LAN, it runs fine and completes all 3 steps successfully. If same TS is assigned to same computer, which is connected via Direct Access, last step, 'Enable Bitlocker' step always fail. Advertisement Log looks like this when attempting via DA... The task sequence execution engine successfully completed the action (Restart Computer) in the group (Activate TPM chip and Enable Bitlocker) with exit code 0 The task sequence execution engine performed a system reboot initiated by the action (Restart Computer) in the group (Activate TPM chip and Enable Bitlocker). The task sequence manager could not successfully complete execution of the task sequence. A failure exit code of 16389 was returned. Any ideas why this last step fails when connected via Direct Access? I'm still able to access all internal resources while connected via Direct Access. Thank you already!!

Ok found the culprit. I was using WiFi network to connect internet, before Direct Access was established. My WiFi network requires web authentication, before allowing traffic to internet. In step 2, my Task Sequence restarts computer. I repeated same steps using cable broadband modem and all steps were successfully completed.
