AutoDial

Is there such a thing as AutoDial? I use Netscape for Web Browsing, and now have a DSL line. Netscape still tries to Dial-up for access. I noticed smoething that said ‘AutoDial’ when this comes up, but haven’t been able to find a setting to disable it. Is there such a thing? By the way, if I cancle the Dial-up box, I get on -line just fine, so it’s not preventing me from getting out, but it is annoying…any ideas?
