After Uninstalling Neverfail Heartbeat, MSEXCHANGEDIAGNOSTICS Service Fails to Start



This Knowledgebase article provides information about the MSEXCHANGEDIAGNOSTICS service failing to start after uninstalling Neverfail Heartbeat.

More Information

Note: Neverfail recommends that before attempting to uninstall Neverfail Heartbeat that you uninstall the Neverfail for IIS Plug-in using the Neverfail Heartbeat Management Client to prevent the occurrence of MSEXCHANGEDIAGNOSTICS service failing to start.


After uninstalling Neverfail Heartbeat and rebooting the server, MSEXCHANGEDIAGNOSTOCS service fails to start.


Neverfail Heartbeat is unable to reset some services to automatic due to permission limitations.


If the Neverfail Heartbeat for IIS Plug-in was not uninstalled using the Neverfail Heartbeat Management Client prior to uninstalling Neverfail Heartbeat, perform the following steps:

  1. Run the following commands in a command prompt (or copy - paste them in a .BAT file, and run it).

    Note: Ensure the commands are correctly spelled.

    sc create FixServiceStartup binPath= "cmd /K sc config schedule start= auto"
    sc start FixServiceStartup
    sc delete FixServiceStartup

    Note: When running the sc start FixServiceStartup command, the command will run for approximately 30 seconds and display the following expected output:

    [SC] StartService FAILED 1053: The service did not respond to the start or control request in a timely fashion.
  2. Start Service Control Manager and confirm that the Startup Type for the Task Scheduler service is set to Automatic .
  3. Reboot the server.
