What happens if you do a google search, then highlight the URL at the bottom of the link discription" right click on the hilighted URL; then paste the link into the address bar? then press enter? is there an error 404 page not found in the webpage/content area, or something like "dns error" at the bottom lefthand side of your internet explorer window, in the status area?

If your browser still will not open this web url, after flushing the DNS cache, open start run cmd, at the command prompt, type in tracert[one space after tracert in the same line]www.domainname.com then press enter..

It should look like the following, except your website address goes where I put the phrase domainname

C:\tracert www.domainname.com

Once you press enter, if you see tracing route to www.domainname.com[number.number.number.number] "this is the IP address of your website"

if it times out "destination unreachable" even after flushing the cache, you may need to restart the network between your computer "laptop" and the server.

If the address matches, DNS is working, but something else is not.
