Reapply schema fails on miscellaneous sections each time you run it. Every time it fails it shows 'Failed parsing response result' as in below
We have found this is due to the "Deny IP address based on the number of requests over a period of time" setting is enabled in Internet Information Services (IIS).
In order to resolve you have to disable it in IIS > IP Address and Domain Restrictions > Edit Dynamic Dynamic Restriction Settings > Deny IP address based on the number of requests over a period of time, as shown below:
This option is not enabled by default when installing IIS. If it has been modified, please disable it.
If you do need the option "Deny IP address based on the number of requests over a period of time" enabled, you can click on "Add Allow Entry" in the Actions pane and set both ::1 and 127.0.0.1 as IP addresses that will be excluded from the rule. This way the reapply schema (which talks to IIS over "localhost" at a rapid rate) will not affected by this rule.
