IIS错误404即使文件存在,aspx也会正常打开

我无法访问html页面或任何图像文件,只有我能够成功访问。apsx asmx和ashx文件。我正在 404-找不到文件或目录

例如:

mysite.com/index.html  ( getting 404 error)
mysite.com/image.jpg( getting 404 error)

mysite.com/page.aspx (working fine)
mysite.com/service.asmx/method  ( working fine)

我尝试过的事情:

1. 正在检查IUSR和IIS\U IUSR的文件夹权限。
2. MIME类型
3. 映射处理程序

我会发布我的网站。配置设置。

向web添加静态内容。配置

 <system.webServer>
        <handlers>
           <clear />
            <add 
                name="StaticFile" 
                path="*" verb="*" 
                modules="StaticFileModule,DefaultDocumentModule,DirectoryListingModule" 
                resourceType="Either" 
                requireAccess="Read" />
        </handlers>
        <staticContent>
            <mimeMap fileExtension=".*" mimeType="application/octet-stream" />
        </staticContent>
