Troubleshooting IIS

For troubleshooting iis related issues,

Event Logs:

1. first check the issue is related to iis configuration.

For that

Go to server manager

in event viewer, application and service logs, Microsoft, windows, iis configuration,

we can see the iis logs related to administrative stuff and operation logs

2. If there is no configuration issue, then go to windows logs, check the application related and system related.

When the site is moving to other server, copy the web.config file so that we can’t do the Settings manually

Web service logs:

go to site and go to logging and troubleshoot the logs

or

web log expert analyzer is the tool for troubleshooting logs

For troubleshooting issues with SSL, we have tool like ssl diagnostics

For site we can turn the Failed request tracing, so that failed requests will be gone to that files

Failed request tracing rules:

We can add the rules like

Trace the php file — *.php, status code–> 401-599
