but I still have the same problem. I have win XP with a
direct cale connection. I also tryed accessig the https
site with Netscape, same problem. I also tryed accessig
the https site using Juno dial-up but still the same
problem. I used a laptop with WIN 2000 on my cable it
worked but my destop & Laptop #2 has win XP pro and I
can't connect.

The problem is from the operating system.

Can anyone help?
