Windows 10: On SCCM server, why would WSUSPOOL IIS application pool be locking out my account?

The server in question is an SCCM server that is used to synchronize updates with Microsoft. I recently changed the password on my administrative account, after which my administrative account became immediately locked out.Analyzing the bad password attempts, it was clear that they were initiated by an IIS worker process w3wp.exe on this SCCM server, and I was able to determine that the worker process was associated with the WSUSPOOL application pool.Here is a sample failed authentication event, with some names changed to protect the innocent. You can see that the wsuspool application pool

WSUSPool in IIS Stops Repeatedly Server 2016

Hi, in our Microsoft Servers 2016 with WSUS Role, WSUSPool in IIS Stops Repeatedly!

Is it possible with PowerShell to do monitoring of WSUSPool in IIS 24/7/365?

Combination of scheduled PowerShell script with SMTP ?

For example from one server check all servers in every 5 or 10 minutes, if status is stopped start it and send mail of incident ?

 

Application pool with custom account crashing

Debug Steps

• Restart the computer if you've not already in case there is a pending update, fragmented memory, etc. just to rule out common issues a simple power cycle eliminates.
  
• Check the Event Viewer logs for both Application and System logs for anything relevant to this issue to see if there's something in there are indicates what the issue may be.
  
• Turn on debug logging to the screen in the config file, restart the app pool, and then try again to see if it displays anything to the screen you may see before the app pool stops.
  
• Turn on more advanced or verbose IIS logging to see if that shows anything relevant.
  
• Set the top/main site to .NET 4.0 or the higher .NET and then set the sites/apps beneath to be the 2.0 or lower framework explicitly. Doing with the higher .NET Framework version and lower implicitly can cause problems like this
  
  • If this web app is within "a main/the default" site of IIS (like a subfolder in the hierarchical IIS structure) see what the top or main site is set to use .NET version wise. If the top level is set to 2.0 or something less than the .NET Framework this app uses, then this could crash the app pool potentially.
    
• Create a new app pool with applicable settings and then set the app to use it and see if that makes any difference.
  
• Run a Wireshark or a TCP/IP sniff of equivalence on the machine see if there are any packets of relevance indicating what the issue may be.
