Common Connection Errors / Solutions

Error 731: Protocol Not Configured

Runtime error 731 is a common connection error that occurs when your computer cannot establish a connection. This may leave the computer or modem in an irresolvable state; therefore, future connection attempts are not going to work as expected. To correct this error, you must first attempt to re-boot your computer. If that fails, we will guide you through additional steps.

How to Re-Boot Your Computer and Modem

  2. Click on the Windows Start button and select Shut Down.

Note: If, during this process, you see a warning about "Version Conflict" or "A file being copied is older," click No. If you are prompted that the "file is not found," you are not using the CD-rom that was used to install Windows on your machine.
