Our application installed on Windows server 2016.

It is build using asp.net. Application pools are getting stopped frequently.
When we try to start its throwing below error. Application pools are configured with machine account.


Cannot Start application pool.

There was an error while performing this operation.
Details:
The Service has not been started error 0x80070426 (Exception from HResult 0x80070426.


Event Viewer:
A Process serving application pool AAA terminated unexpectedly. The Process id was '53376'. The process exit code was 0xffffffff.

What I have tried:

I tried reset of IIS but it is not helpful. Same error is throwing after IIS reset.
Also I have stopped and started application pool. But it is not allowing me to stop/start because it is throwing same error.

If I restart the server Application pool is started working.
As a workaround I am restarting the server whenever we get this application pool stopped issue.

What account is your application pool setup to use?

Using Machine(service) account.

fix your system Image and kernel object:
in cmd prompt : "sfc /scannow && dism /online /cleanup-image /restorehealth"

I am not convinced ASP or IIS are involved for this case...
