Permalink Trouble with IIS Rewrite

Hi guys

I have two sites – ppcglasgow.co.uk and ppcacademy.co.uk. I used the URL Rewrite module in IIS on both of them, but ppcglasgow.co.uk still displays index.php in the URLs. When I try the rule, the sub links work but the homepage doesn’t resolve.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    <rewrite>
      <rules><rule name="RemoveTrailingSlashRule1" enabled="true" stopProcessing="true"><match url="(.*)/$" /><conditions><add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /><add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /></conditions><action type="Redirect" url="{R:1}" /></rule><rule name="Main Rule" enabled="true" stopProcessing="true"><match url=".*" /><conditions logicalGrouping="MatchAll"><add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /><add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /></conditions><action type="Rewrite" url="index.php/{R:0}" /></rule><rule name="non www to www" enabled="true" patternSyntax="Wildcard" stopProcessing="true"><match url="*" /><conditions logicalGrouping="MatchAny"><add input="{HTTP_HOST}" pattern="ppcglasgow.co.uk" /></conditions><action type="Redirect" url="http://www.ppcglasgow.co.uk/{R:0}" /></rule>
				<rule name="wordpress" enabled="false" 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>
    <defaultDocument>
      <files>
        <clear />
        <add value="Index.php" />
        <add value="Index.html" />
        <add value="Index.htm" />
        <add value="Index.cfm" />
        <add value="Index.shtml" />
        <add value="Index.shtm" />
        <add value="Index.stm" />
        <add value="Index.php3" />
        <add value="Index.asp" />
        <add value="Index.aspx" />
        <add value="Default.htm" />
        <add value="Default.asp" />
        <add value="Default.aspx" />
      </files>
    </defaultDocument>
  </system.webServer>
</configuration>

Can anyone tell me what I might be doing wrong, or has anyone had this problem before?
