Wordpress 500 (URL Rewrite Module Error.)

Question

I am hosting a Wordpress website in IIS 8 I am getting the following error:

Failed to load resource: the server responded with a status of 500 (URL Rewrite Module Error.)

When I upload a new image and display. If I go to wp-content and give IIS_USRS access then the image works, when I add a new image I have to remove IIS_USRS and add it again for the image to work

If I use the following web config the website never loads

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
  <rules>
    <rule name="wordpress" patternSyntax="Wildcard">
      <match url="*" />
        <conditions>
          <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
          <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
        </conditions>
      <action type="Rewrite" url="index.php" />
    </rule>
  </rules>
</rewrite>

Answer 1

I changed the permissions in the security tab to the wp-content folder of wordpress within the iis manager, it was necessary to edit and then I gave full control to IIS_USRS and the error was solved
