ALso for me and for some ppl domain works fine and for some nothing of above works and i pinged onine..it is pninging fine..so what could b the prob??? any ideas??
I think he just has a general question and doesn't want to reveal his domain name. Try pinging both using command prompt. If you don't get a response from both then you got a problem.
Oh sorry I may have miss understood you can contact your web host who will be able to sort the issue. the problem will be where the DNS (Domain Name Server) resolves the domain name to an ip address. this can be a common fault with new domains and will take a matter to seconds to fix.
This could be for two reasons: 1. Not exist DNS record for www.domain.com 2. In your Web server is not configured to support www.domain.com. Like "ServerAlias www.domain.com"
Actually you should not make them both working!; from SEO point of view your best way is to do a 301 redirect of all your www.domain.com to domain.com to avoid duplicated posts in search engine SERPs.
