I am new to iis, when I try to access the site, I get the following error：
Module IIS Web Core Notification BeginRequest Handler Not yet determined Error Code 0x80070021
I tried to search for similar problems through Google, and tried the steps in the link below, but without success.
HTTP Error 500.19 and error code : 0x80070021
Can some one help me? Thanks in advance.
According to your description and error mesage, it seems something wrong with your web.config.
The 0x80070021 error occurs if the specified portion of the IIS configuration file is locked at a higher configuration level.
I suggest you could refer to below article to know how to unlock the configuration.
