Ok I know this has been asked before and answered before but I can not find the post and tried a few search keywords with no luck.

My question is:

I setup an account on my dedicated server. Now I want that account to be accessible using http://www.domainname.com AND http://domainname.com

Right now when I go to the site using the www. the site works but if I dont use the www. I get the Cpanel message saying their is no site configured at this location?? Funny thing is my other accounts on this same box work with and without the www. ???

Any idea what I need to fix on this one account to get it to work like I want

Thanks All for help and your time
