thanks. yes, my internet explorer was set to go through proxy, but netscape is directly connect to the internet.
so to explain the problems i run into is that
due to explorer goes through proxy and netscape does not. so they are using different path.
and on netscape path, the DNS servers records had updated, so my new domain is recognized. but on the internet explorer path, the DNS servers records was not updated in time this morning. so it cannot recognize the domain name. so i have seen the problems that netscape works but internet explorer doesn't work.
but in the afternnoon, all the DNS servers are updated, so both internet explorer and netscape work fine.
am i right?
