Mozilla help

[hils]

For some reason whenever I open Mozilla now I don't get the dialup screen to connect to the internet. Instead I just get told that I'm not online and the page can't be displayed. I have to go to my internet connections screen, connect manually and then open Mozilla. This seems to have happened when Window installed Service Pack 2. Any idea how I fix it? I've looked at the options screen for both Mozilla and my internet connection and I can't see what to do
