I have a problem with Microsoft ISATAP Adapter #3 driver

goto device manger from my computer properties and hardware with yellow caution i symbol have something wrong

Greetings,

On a Windows Vista-based computer, the Microsoft ISATAP adapter appears with a yellow exclamation mark (!) next to it in Device Manager.
You can safely ignore this error message. This error message does not indicate a problem with the adapter. The adapter will continue to work correctly.
Check out this article for more information on this:

If this is still not working,
First try to reset Winsock from command prompt, this will reset all the Network components to default:
Click on start, type CMD,'Right click and Run as Administrator'.
At the command prompt type:
netsh winsock reset catalog
In such a case, I suspect this problem to be caused by network adapter missing or corrupt. Please firstly reinstall the driver for your wireless network adapter. Then try to reinstall Microsoft ISATAP using following steps:
1.In Device Manger, right-click the item of Microsoft ISATAP and select Uninstall.
2.Still in Device Manager, click Action and select Add legacy hardware.
3.Click Next, and select Install the hardware that I manually select from a list (Advanced), click Next.
4.Select Network Adapters and click Next.
5.Select Microsoft in left panel and Microsoft ISATAP Adapter in the right panel.
6.Click Next and finish the remaining wizard.

Hi.
Let me explain you about the Microsoft ISATAP Adapters.
ISATAP (Intra-Site Automatic Tunnel Addressing Protocol) is an IPv6 transition mechanism meant to transmit IPv6packets between dual-stack nodes on top of an IPv4 network.
It is a Windows Operating System Generic Driver.
This Driver will be installed automatically.
As this is a Windows default Driver, it has no specific functions.
As you are able to view the "yellow exclamation mark", you may just un-install the Driver..
This should not change the functionality of the Computer.
1) Right-click on the "ISATAP Adapter" in the Device Manager. 2) Then, click on "Un-install". 3) This should un-install the Driver. 4) Once you have done the above steps, restart the Computer for the settings to be enabled.
Performing the above steps should resolve the issue.
Hope this helps.
Please feel free to contact for further information and assistance.

Check this forum out, looks like that adapter is not needed http://www.vistax64.com/vista-networking-sharing/30771-microsoft-isatap-adapter.html

Run the System Recovery

simply update drivers

It is discontinued, so you will most likely need to buy a new adapter as it is unlikely that there is a 64-bit driver available.  Make sure that any adapter you buy has Vista 64-bit support.  Try the following google search: "64-bit USB to serial adapter"
