ProCessor on "web.config redirect problem"

Hi there,

I am having trouble configuring the web.config file (host uses windows IIS servers).
With permalink setting to /%postname%/ a 404 error occured (when visiting homepage), the rest of the pages worked perfectly (with .../slugname).

In order to fix the issue with the homepage, the host had configured this web.config file:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
      <rewrite>
        <rules>
          <rule name="Main Rule" 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>
        </rules>
      </rewrite>
       <httpRedirect enabled="true" destination="/home" childOnly="true" />
      </system.webServer>
</configuration>

Now it works, but yet another problem occurs.
The Wordpress Dashboard isn't reachable anymore by /wp-admin or /wp-login.php

Both are changed to /home/wp-admin or /home/wp-login.

Any idea on how to fix this?
Is there an option to exclude *.php files or something from redirecting?

Hope you can help out!
