For a couple of weeks, some applications in IIS have stopped responding, when trying to access the site, the app return the error:
On Windows Event Log, I found 2 events in the Application Log: 2297 and 2307:
The worker process for application pool 'Appname' encountered an error 'Cannot read configuration file
' trying to read configuration data from file '\\?\C:\inetpub\temp\apppools\AppName\AppName.config', line number '0'. The data field contains the error code.
and:
The worker process for application pool 'CourrierTlsWeb' encountered an error 'Cannot read configuration file
' trying to read global module configuration data from file '\\?\C:\inetpub\temp\apppools\AppName\AppName.config', line number '0'. Worker process startup aborted.
When this happens, we recycle the Application pool of the Webapp and the site return online. I have checked antivirus to see if it's blocking the config file, but haven't find any indicator that the AV could be blocking the file. I have also checked the disk but haven't found any error either. What could be causing these events?
This is running on Windows Server 2019 STD.
Best Regards.
UPDATE Apparently the DFS has something to do with this. There are 2 IIS server that sync the configuration folder. I have followed this article:
