How to use IIS on windows 10?

I wanted to create a website where you can download my apps and I wanted to use wordpress or weebly but I want to be in full control of my website, like even the 404 webpages have to be deigned by me. so after googling it, I found that you can Internet Information Services to host a website on windows 10, so I went to optional windows features and I turned it on from there. when creating a website, I specified the location of accessing files to be in D:\website\res

but then it says The server is configured to use pass-through authentication with a built-in account to access the specified physical path. However, IIS Manager cannot verify whether the built-in account has access. Make sure that the application pool identity has Read access to the physical path. If this server is joined to a domain, and the application pool identity is NetworkService or LocalSystem, verify that <domain>\<computer_name>$ has Read access to the physical path. Then test these settings again.

I have no idea what this is, please help me guys I really the website. note: it gives this message in any location. and I even enabled permissions for the IIS accounts.

Solution 1:

This is a by-design "benign" warning simply telling us a verification has been deferred to runtime. This can be ignored in most cases (if you are sure that the accessing users will have access permissions).

With pass-through authentication, it uses the authenticated user. That will either be the anonymous user, the application pool identity, or the passed credentials if using basic or integrated authorization.

Most likely the reason for the message is that you have disabled Anonymous access and chosen instead Integrated Windows authentication. As the user's credentials cannot be known in advance, IIS is warning you that they might be insufficient to access the resource. IIS cannot know in advance which user account will access the site.
