Removing Cached pages

I have a domain that I have had for some time but I just activated it at 1and1.com
Every time I try and browse to it from my laptop I get the default screen that 1and1 put out for newly registered domains BUT if I go to a XP machine I have on the same network it works just fine and displays the Index.html. I have also tried this at home (another completely different network) as well and get the same results.

I have tried deleting history under Internet Options and ipconfig /flushdns but I still get sent to the wrong page. Where the heck do they keep the cache files in Win7/Vista????

THANKS

EDIT: I created another user and I can browse to the page just fine. So the issue is limited to my user name.

Go to Internet Options
Under Browsing History click Settings
Under check for newer versions of stored pages check "everytime"

Obviously what I was doing was not removing cached pages.
Also on this Browsing History screen it will tell you WHERE your temporary Internet files are stored.
This problem has persisted since last week and since I had "Automatically" selected it was not doing its job properly.
