An IIS error log is a file that contains information about errors that have occurred on an IIS web server. This information can be used to troubleshoot problems with the web server or with applications that are running on the server. To check the IIS error log, you can use the Event Viewer application. To open Event Viewer, click on the Start button and type “eventvwr.msc” into the search box. Then, expand the “Windows Logs” node in the left-hand pane and click on the “Application” log. The IIS error log will be listed in the right-hand pane.
The IIS error log is an important tool for troubleshooting problems with an IIS web server. By checking the error log, you can identify the source of the problem and take steps to resolve it. The error log can also be used to track the performance of the web server and to identify trends that may indicate a problem.
