Fun with UAC – Change Machine Identity Failed Error.

Posted on by shadedred

Change Machine Identity failed: Reason: RunProcessWithLogon: Failed to create process [D:\PCHost\al_agent\bin\alagentservice.exe] with user <My PC User> windows error code [183].

My team recently was encountering the error above on multiple VMs after a server patching was completed. The maintenance re-enabled UAC which disabled communication from the PC Hosts and ALM which caused the systems to be Non-Operational.

After a little digging, UAC was determined to be the culprit. For Server 2012, update the registry below to disable UAC.

  1. Browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
  2. In the right pane, double-click EnableLUA
  3. Change Value Data to 0
  4. Reboot the Host, Attempt to Re-Configure in the LAB
