I too have the dial up connection problem. My ISP is Wanadoo and I raised the matter with them.I think my promlem first surfaced after a windows update a week ago Incidently the problem is not causing any trouble only an iritation. gel This is the reply from wanadoo There are a number of reasons why a 'Connection' window may appear when you first turn on your computer. These can include a request from MSN Messenger, Virus checking software or any programs that appear in your 'System tray' requiring an Internet connection.
The 'System tray' is the collection of icons located in the bottom right hand corner of your desktop, found beside the clock.
You will need to check through your 'System tray' and see if any of the programs located there are set to dial a connection automatically.
