BuddyPress.org

I have some serious problem using BuddyPress with IIS and SQL Server 2012.
My WordPress version is 3.5.1
BuddyPress version is 1.7.2 , IIS 8 , SQL Server 2012.
I am using wordpress-database-abstraction for using SQL Server.

My problem is when I install BuddyPress and activate it, the pages like Activity, Groups , Members Leads to wrong pages.
Permalinks for these pages are like “http://localhost/wp-sqlsrv/index.php/activity/” ,”http://localhost/wp-sqlsrv/index.php/groups/”
these pages only have Title Like Groups ,Activity and not anything

But if I change the url for Groups page from “http://localhost/wp-sqlsrv/index.php/groups/” to
“http://localhost/wp-sqlsrv/groups/” then I see the correct page.

why these permalinks are wrong and how to make them correct
I am using URL Rewrite 2.0
and My web.config is
<?xml version=”1.0″ encoding=”UTF-8″?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name=”WordPress Rule” stopProcessing=”true”>
<match url=”.*” />
<action type=”Rewrite” url=”index.php” />
<conditions logicalGrouping=”MatchAll”>
<add input=”{REQUEST_FILENAME}” matchType=”IsFile” negate=”true” />
<add input=”{REQUEST_FILENAME}” matchType=”IsDirectory” negate=”true” />
</conditions>
</rule>
</rules>
</rewrite>
<defaultDocument>
<files>
<remove value=”index.php” />
<add value=”index.php” />
</files>
</defaultDocument>
</system.webServer>
</configuration>

Any help ! I am struggling from 3 days for this.
