Missing Network protocol

Updated: 04/26/2017 by Computer Hope

missing network protocolBefore any of the steps below are attempted, verify that your network card is installed and has no errors or conflictions in Device Manager. If your network card has errors, see the basic network card troubleshooting page.

Keep in mind that the three most common protocols used on the majority of all computers are TCP/IP, IPX/SPX and NetBEUI. It is very unlikely that any other network protocol needs to be installed. Finally, it is common for a computer to have all three of these protocols installed at the same time. Installing one or more different protocols does not cause issues with a computer.

Microsoft Windows ME, 2000, and XP users

  1. Open the Control Panel
  2. Double-click "Network and Dial-up connections."
  3. Double-click on the "Local Area Connection."
  4. Click the Properties button.
  5. If the protocol is installed, the protocol should be listed by the installed network adapter. Note: do not confuse the network adapter with the dial-up adapter. If the protocol is listed it is not missing. If you want to reinstall the protocol, highlight the protocol and click the remove button, reboot the computer and then continue with the steps below.
  6. If the protocol is not listed, click the Add or Install button.
  7. Select the protocol and click ok. If this is a corporate network and you are unfamiliar with the network you are connecting to, attempt first to install the protocol. If this does not work, we recommend you contact the network administrator or your corporate help desk for additional assistance.
  8. Once the protocol has completed the installation, unless you want to install additional protocols, reboot the computer.

Microsoft Windows 95 and 98 users

  1. Open the Control Panel
  2. Double-clicking "Network."
  3. If the protocol is installed, the protocol should be listed by the installed network adapter. Note: do not confuse the network adapter with the dial-up adapter. If the protocol is listed it is not missing. If you want to reinstall the protocol, highlight the protocol and click the remove button, reboot the computer and then continue with the steps below.
  4. If the protocol is not listed, click the Add button.
  5. Select Microsoft as the manufacturer. If this is a corporate network and you are unfamiliar with the network you are connecting to, attempt first to install the protocol as a Microsoft protocol. If this does not work we recommend you contact the network administrator or your corporate help desk for additional assistance.
  6. Under the network protocol select the protocol you want to install. This should be TCP/IP, IPX/SPX or NetBEUI. Unless you are attempting to install a different protocol.
  7. Once the protocol has completed the installation, unless you want to install additional protocols, reboot the computer.
