Reference number: CH000470

Missing Network protocol.

Issue:

Missing Network protocol.

Cause:

Protocol has not been installed or has been removed.

Solution:

Before any of the below steps are attempted, verify that your network card is installed and has no errors or conflictions in Device Manager. If your network card has errors, please see document CH000445 for additional information and help with resolving those issues first.

Please 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 will need 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 types of protocols does not cause issues with a computer.

Note: If you are getting an error about the protocol version, please see document CH000471 for additional help and information.

Microsoft Windows 95 and 98 users

1. Open Network properties by clicking Start / Settings Control Panel and double-clicking "Network."
2. 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 wish to re-install the protocol, highlight the protocol and click the remove button, reboot the computer and then continue with the below steps.
3. If the protocol is not listed, click the Add button.
4. Select Microsoft as the manufacturer. If this is a corporate network and you are unfamiliar with the type of 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.
5. Under the network protocol select the protocol you wish to install. This should be TCP/IP, IPX/SPX or NetBEUI. Unless you are attempting to install a different type of protocol.
6. Once the protocol has completed the installation, unless you wish to install additional protocols, reboot the computer.
