1)I bought this domain name.
whostz.info

2) Taken hosting from here: www.techiehost.org
and added ns1.techiehost.org and ns2.techiehost.org as my domain nameserver.

3)Than I signed for Microsoft Live domain service here :
http://domains.live.com

After signing up at Microsoft live domain service, I got some DNS setting for my domain name.

4) Loged in my domain control panel.Did required DNS setting.But my domain name ask me to add 4 nameserver to activate my DNS service.

5) So, I added nameserver mentioned in my domain control panel.

Some times, my site does not open without www
Some times, manage DNS page in my domain control is not opeing.
