There was an earlier post with this topic name but the answers there do not seem to apply to my case.
For years I've been able to stop IIS and start w3wp in debug mode on those rare occasions when I needed to catch the application at startup.
net stop w3svc
%windir%\SysWOW64\inetsrv\w3wp.exe -debug
At some point this command began to result in the following error
ERROR: There was an error reading the configuration. Please check that the configuration file is exists, is accessible and contains valid configuration.
This is the case on both my development systems.
I've made do without having debug ability but I would like to get that back
My development systems are Win 10. The only web applications use DefaultAppPool on the Default Web Site.
Can someone tell me what this error message is trying to say and what I should look for
