The error log of IIS is usually located in a specific folder, which records the errors and exceptions that occurred on the server. These logs can provide detailed information about problems with a website or application. By default, IIS error logs are stored in the following path:
C:\inetpub\logs\LogFiles
In this directory, you can find u_errYYMMDDerror log files named in the format, which YYMMDDrepresents the year, month, and day. These files contain information such as server errors, HTTP errors, application pool crashes, etc.
View the access log file ( u_exYYMMDDnamed with the format).
