The Dynamics AX Object Server 5.0 service terminated with service-specific error 80 (0x50)

When attempting to start the AOS Service after changing the Log on, the following error appeared:

Windows could not start the Dynamics AX Object Server 5.0$01-[Application] on [Server].  For more information, review the System Event Log.  If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code 80.

System Event Log:

The Dynamics AX Object Server 5.0$01-[Application] service terminated with service-specific error 80 (0x50).

This occurred regardless of any database permissions.  The workaround was to apply the following permissions to the following folders:

  • %ProgramFiles%Microsoft Dynamics AX50ApplicationAppl[Application]
    • Modify, Read & execute
    • List folder contents
    • Read
    • Write
  • %ProgramFiles%Microsoft Dynamics AX50Server[Application]Log
    • Read
    • Write

While the AOS Service was down, the following error got written into the Application log each second:

Microsoft Dynamics AX Business Connector Session 7.
RPC error: RPC exception 1722 in Ping occurred in session 50

    For wich account did you apply those permissions? I’ve set it for both the user under which the service is running and the computer-account from the server which runs the AOS. I still get the same errormessage.The system log says:The Dynamics AX Object Server 5.0$01-AX09SP1TWDEMAOS service terminated with service-specific error 80 (0x50).The application log says:Object Server 01: Failed to create file axapdar.ahi. Error code was 5andObject Server 01: The application files are not accessible. This can be caused by another Microsoft Dynamics instance using the application files in exclusive mode.

    I set the permissions for the AOS Service account. Maybe in your case, you need to give the AOS Service account modify rights on the server log?
