Jumping the gun here a bit.... some causes could be: another application is requesting access to the internet such as Outlook Express or your anti-virus program, or you have a virus/spyware that wants to connect. Update and run your antivirus program, download and run Spybot http://www.safer-networking.org/ .
Check the settings in any programs you run online and make sure they are not set to "connect automatically".
