ArcGIS Server failure issues following Windows Server patching updates

[HenokA]

We are having a problem with a standalone ArcGIS Server 10.9.1 that keeps failing every time there is a periodic non-ESRI patching (Windows Server patching). Then the ArcGIS Server service has to be manually restarted to bring Server back online.

And simply going for manual ArcGIS Server service restart does not address the issue and throws 

"Error 1069 : The service did not start due to logon failure".

Instead,  the ArcGIS Server account password has to be re-entered before successfully restarting manually.

It appears some operating system process is likely modifying the ArcGIS Server Service Account password during the Windows Server patching update, as perhaps explained in this ESRI workaround. 

Any hint or workaround to resolve this issue? What aspect of the Windows  Server patching is likely forcing this change in the ArcGIS Server Service Account password leading to ArcGIS Server failure?

Greatly appreciate your response to this,

Thank you.

Hello @HenokA  your ArcGIS Server account will be a Windows user, either Local or Domain. And if a Windows patch resets a Windows user's password, then I think you need to ask your IT people to help. Perhaps the patch is enforcing a password complexity or re-use policy that was not there before.

You could try a simple test of the user's password, eg right-click on a Notepad icon, select Run as a different User, and enter the ArcGIS Server account credentials there. That will confirm if the problem is indeed the password or something else like permissions etc
