Hi <-^~-Kushani-~^->,
Here is the Steps
For this to work, you need to have your dial up connection set up and username, password and phone number saved on the connection.
On Windows XP:
1. Open Control Panel and open Network Connections
2. Dial up and LAN connections you have created on your machine will be listed. Find the dial up connection you want to auto dial on startup, right click it and select properties.
3. Open the ‘Options’ tab. Uncheck the checkbox that says ‘Prompt for name, password, certificate, etc”. Also uncheck the ‘Prompt for phone number’ checkbox.
4. Press ok to close the options dialog.
5. Back in the Network Connections window, right click the dial up connection you just modified and click ‘create a shortcut’. Allow the shortcut to be placed on desktop as per the warning message.
6. Cut the shortcut from the desktop and paste it in your Start Menu—>Startup folder.
thanks
