and at the top of the page click on Tools>Internet Options>Connections.

About half-way down you have three options to check. Check the O Dial whenever a network connection is not present.

I use Earthlink and if I click on the IE icon on my toolbar, a dial-up box appears and I have to enter my password. Then, after dial-up, the IE page appears

However, I never use this method because it does not load the Earthlink Toolbar. I get started by clicking on the Earthlink icon on my toolbar, the connection program runs, the Earthlink toolbar appears and there is a pause while Earthlink checks for email. I then click on Web or Home or Favorites and my Mozilla Firefox browser page appears.
