now you see it now you don’t……

I can access my web site running on a win2k system when i enter the static IP address in a browser on a stand alone computer with a normal dial up connection, but I can’t access the site when i type in its full domain name( I keep getting an “Under Construction, The server you were trying to reach does not currently have a default page…..” message) I get this same message when i try to access the system from one of the PCs on my local LAN. I’ve a feeling it’s down to my DNS settings, but i’ve already had these registered with my domain name service provider. if anyone has any other ideas they’d be well appreciated.

Thanks in advance……
