module not appearing in modules page

[Ajay_11]

Hi,

I am a beginner in magento development, I tried to write module by following this link:

http://alanstorm.com/magento_controller_hello_world

In my magento system, the file paths are like this:
C:\wamp\www\magento\app\code\local\ajaykulkarnidotcom\hello\etc\config.xml
And contents of config.xml are

<config>
    <modules>
        <ajaykulakrnidotcom_hello>
            <version>0.1.0</version>
        </ajaykulkarnidotcom_hello>
    </modules>
</config>

and contents of C:\wamp\www\magento\app\etc\modules\ajaykulkarnidotcon_hello.xml are

<config>
    <modules>
        <ajaykulkarnidotcom_hello>
            <active>true</active>
            <codePool>local<codePool>
        </ajaykulkarnidotcom_hello>
    </modules>
</config>

After saving above files and refreshing modules page in magento admin page doesn't display the module ajaykulkarnidotcom_hello.
I checked filepaths and spellings more than dozen times, and still unable to fix it. Please help me.
