Microsoft ISATAP network adapter RRS feed

  • Question

  • Hello,

    I recently bought a laptop with a vista operating system and have spent the past few days setting it up. I decided to perform a one care safety scan to check for problems on my system and afterwards the computer informed me of an error with my ISATAP network adapter (code 31). I read up on it and was informed by microsoft that it is a common error and to disregard it. I figured that this error was somehow caused by the onecare safety scan so i uninstalled the adapter and then reinstalled it, and it seemed to install it fine, but when i went to look in the network adapters list in device management, the adapter was knowhere to be found. So i then decided to perform a system restore and this did not remedy the problem either.

    Could someone please give me advice on how to reinstal the driver so that it appears in its rightful place (network adapters).

    Hi,

     

    Thank you for your post.

     

    I assume that you cannot find your ISATAP network adapter in Device Manager.

     

    Based on my research, I will share the following information with you:

     

    Device Manager displays information about the hardware devices installed on your computer. However, you may not have noticed that Device Manager does not actually list all the hardware. There are two types of devices are hidden in Device Manager: non-plug and play devices and ghosted devices (non-present).

     

    To show these devices, please open Device Manager, and then click on the view tab and select the option “Show hidden devices”.

     

    After this, please check if your ISATAP network adapter appears under the Network adapters.

     

    Meanwhile, if the ISATAP network adapter still cannot be found or a error receives, it is also a expected behavior. Please also refer to the following Knowledge Base:

     

    On a Windows Vista-based computer or on a Windows Server 2008-based computer, the Microsoft ISATAP adapter appears with a yellow exclamation mark next to it in Device Manager, and you also receive an error message

    I would like to share the following documents as well. Hope they are helpful:

     

    View Details and Status for a Device(Note: please note the section of View hidden devices)

  • Thank you very much for you support, i found it very helpful

    The adapter seemed to appear in the network adapter drop down box after the view setting were set to show hidden devices. I find it unusual as to why it is now a hidden device, one of your articles sudgested it was because the adapter is not present, does this have something to do with it not being in use at the present moment?

    Nether the less, thank you very much

    Hi,

     

    Thank you for your update. I am glad to hear that my suggestions are useful. It is my pleasure to help you.

     

    At this time, I would like to share the following information:

     

    In Device Manager, there are two types of hidden devices in addition to the typical devices that are displayed:

     

    Typical hidden devices, which are not displayed (non-Plug and Play drivers, printers, and so on).

    Phantom devices, which are not currently connected to the computer.

     

    Please understand that it is by design that the Intra-site Automatic Tunnel Addressing Protocol (ISATAP) network adapter is hidden. Thus, we need to select “Show hidden devices” to let it appear.

     

    However, if the hidden device encounters an error, sometimes it will appear with yellow exclamation mark to get your attention. As you found that the ISATAP network adapter is not hidden previously, you also noticed that an error received simultaneously.

     

    For more information, please also refer to:

     

    Intra-site Automatic Tunnel Addressing Protocol (ISATAP) Deployment Guide

    Hope this helps.

     

    Thanks.
