Problem Viewing My Website using "www"

[AzazlRue]

Hi Guys
Just Joined and I am Having a weird problem with my website.When I go to view my site using "www" I get The "address not found" error message Same goes with my Cpanel and WHM (I have a hosting reseller website)
However if I Remove the "www" from the address The page will load fine (same with Cpanel and WHM)
This Problem happens periodically Through out the day It will go out and come back.My Host informs me that they can view the "www" on several different PC on Several different connections and I have had a few other people tell me the same thing so I am pretty confident it is on my end.I do not have problem loading any other page.
I have tried Firewall On/off , virus on/off , /flushdns , /registerdns , winsock repair (that sucked I didn't relise I had so many registered apps lol) Opening Ports 80 and 8080 through windows firewall and praying to the internet gods but nothing works.

My Specs

Win Xp sp2 (well actually sp3 but I don't think that qualifies)
2.4 gig cpu
1024 gig mem
10meg dsl with Embarq using the 660r modem (has a built in firewall I have
shut off and Nat included that I have port 80 and 8080 open on)
AVG ver 8.0.169 anti virus with link scanner , web shield and resident shield disabled.

If you need any other info let me know.

On a side note my host recently migrated servers and all WHM reller hosts had to change IP at our register and the problem has been occuring more often since.

Thanks in advance.
Az

Site Url is: www.capitalistwizard.com

When I type in capitalistwizard.com I can view the site no problems but add "www" and I get the 404 error
---------------------------------------------------------------------------------
C:\Documents and Settings\Az>nslookup capitalistwizard.com
*** Can't find server name for address 192.168.2.1: Non-existent domain
*** Default servers are not available
Server: UnKnown
Address: 192.168.2.1

*** UnKnown can't find capitalistwizard.com: Server failed

C:\Documents and Settings\Az>nslookup www.capitalistwizard.com
*** Can't find server name for address 192.168.2.1: Non-existent domain

*** UnKnown can't find www.capitalistwizard.com: Server failed

When The site is viewable for me I can ping and do a tracert but when it isn't it wont do either

Is 192.168.2.1 a server or router? That looks like the problem, I suspect its a server.

Easy fix is to set yourself up with an open resolver like http://www.opendns.com/, if thats not possible I can talk you through fixing 192.168.2.1

I am On an embarq dsl modem which i believe works like a router (has a built in firewall) and gives you a generic IP of 192.168.2.1 (going to http://192.168.2.1 opens a config window with settings I currently have the firewall shut off through it) I am not really confident enough to go in and mess with the settings very much..

Btw my www. is viewable at the moment for me but if it follows the pattern it will be unviewable in the next hour or 2.But while it is viewable here is a working nslookup for both the "www" and Non "www"


C:\Documents and Settings\Az>nslookup www.capitalistwizard.com
*** Can't find server name for address 192.168.2.1: Non-existent domain
*** Default servers are not available
Server: UnKnown
Address: 192.168.2.1

I'd rule out the router for the time being, the 2nd nslookup looks good. The other mostly likely causes are either your hosting company who you've checked with or you ISPs DNS. Try changing it at router level to an open resolver

Think I am going to need a walk through for that
