...connect to your ISP first(dialer) to access the Internet, then access the website via a browser.
It seems that you are accessing a web site (via IE ?) without first dialing up to your ISP (Internet Service Provider).
However, you can select your connection options at (if you are usng IE) Tools>Internet Options >Connection Tab. Here, I suggest ''Always dial my default connection'' whereby you will be connected(dail up) to your ISP automatically. If you are on BroadBand, then it is advisable to select ''Do not make a connction''; then you will have to configure your Broadand modem to connect automatically to your ISP when you ''switch on'' the computer.
Every time I switch on my machine and try to connect to the internet, I get a dialogue box: Web page is unavailable while offline. To view this page, click connect. When I click connect, I can view the page and don't get the error message again until I switch off the machine.
Why does this happen?
