Shenan
Thank you very much for your advice.
BTW, my web hosting company or ISP is pretty irreponsible. When I first
reported my problem to them, their first reponse is to disconnect us from
their network so that their clients won't be affected. :-(
I will look into the MS site for more info.
Thanks again
Anthony
