Do you often get a busy signal when you try to connect to your Internet service provider? As long as the connection was initiated by you (as opposed to an automatic dialing response from an application, such as your Web browser), Dial-Up Networking will redial the number if it can't connect the first time. This feature saves you from having to attempt the connection again manually.
Open up My Computer and double-click Dial-Up Networking. Select Settings in the Connections menu, and select Redial. Fill in the Between tries wait option to set the timing between each redial, then select a number next to Before giving up retry. Click OK to make the settings stick.
