Common Connection Errors / Solutions

Error 633: The port is already in use or is not configured for Remote Access dial out.

There are several possible causes for this error. The steps below should help you pinpoint the cause of the problem and offer a solution.

A. Have you checked your modem and phone cord?

A bad modem or the phone cord not being plugged in might be the culprit. Make certain that all of your phone line connections going in and out of the modem are tight and secure, then try to connect to NetZero again.

B. Have you completely restarted the computer?

Try shutting down and unplugging the computer for 1 minute. Restart the computer and try to connect to NetZero again.

Note: If you have an external modem with a separate power cord, once the computer is shut down, unplug the modem power for 1 minute, plug the modem back in, then turn on the modem and restart the computer before attempting to dial again.

C. It is possible that another program has accessed your modem and has not released it.

It is possible that another software program, such as fax software, is holding on to your modem. The modem can not dial another number until the software releases it. To verify whether your modem is being used by another program, please follow the steps below:

1. Press and hold the Ctrl, Alt and Delete keys at the same time.

      Note: Each time that you click on the End Task button, you will have to press and hold the Ctrl, Alt and Delete keys to bring the Close Program window back up.
   4. Try your NetZero connection again. If this resolves the problem, close NetZero and restart your machine. Repeat the above steps, clicking End Task for only one program at a time. Each time you use End Task, try your NetZero connection again. If you encounter the error again, you will know which program is creating the conflict.

After disconnecting from NetZero, you can launch the applications that you had closed again by restarting your computer.

3. Select the Diagnostics tab.

5. Click More Info.

   Note: If you receive an error message, then you will need to configure your modem. This may require that you reinstall your modem drivers and/or configure your modem settings. If this is the case, you should contact your modem or computer manufacturer for information on configuring your modem. If you are on a LAN (Local Area Network), contact your Network Administrator for assistance.
