需要给文件夹添加权限

You need to assign permissions for IIS_IUSRS on the local machine (but you don't have to assign for IUSR, in fact it will work even if you explicitly deny permissions).

To assign permissions, just right click on the folder and on the security tab make sure to grant the correct permissions, and if the user is not listed then click "ADD", and enter IIS_IUSRS (and make sure that under "domain" the local computer is selected, or enter in the name field YourLocalComputerName\IIS_IUSRS), and then you are good to go.

If you want you can instead of assigning permissions to the IIS_IUSRS group, you can instead assign to the app pool which should in general be "IIS APPPOOL\ app pool name".

首先确认一下是否有Users的权限，如果没有的话，在本机下面添加

用systeminfo命令查看自己的computer name搜索出来，然后加上反斜杠，再加上IIS_IUSRS。进行check

Application Pool的权限，也是在本机添加

需要调整一下iis中website的authentication，或者在web.config中允许所有用户访问

https://stackoverflow.com/questions/20683522/an-error-occurred-while-accessing-the-resources-required-to-serve-this-request

允许所有用户访问

<system.web>
    <authorization>
        <allow users="*" />
    </authorization>
</system.web>

设置权限

This is an old question but the answer is seriously insecure, you should add and enable the authentication provider that you require rather than giving anyone authorization.

To add the provider:

https://www.iis.net/configreference/system.webserver/security/authentication/windowsauthentication/providers/add

To enable the method:

1. Open the IIS Management Console on the web server

2. Expand the Sites folder

3. Double-Click the IIS - Authentication option

4. Under Authentication, select the Anonymous Authentication and click 'Disable' in the Actions pane on the right

5. For Windows Authentication: Select the Windows Authentication and click 'Enable' in the Actions pane on the right

6. For Basic Authentication: Select the Basic Authentication and click 'Enable' in the Actions pane on the right
