I got ISATAP adapter issues on my vista laptop. In device manager there is a little yellow triangle next to each of my ISATAP adapters

It means it is not succeed, probably it is not compatible, or it needs special settings.

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.

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.

Step2:

The ISATAP is related to Internet Protocol 6.

Please check if IPv6[Internet Protocol version] is enabled on your computer to obtain an IPv6 address.

however this driver only pertains to ipv6, so your internet adapter should still function properly. if it is, you can do this:

Disable but leave ISATAP in the hardware list and go to your manufacturers Website
and check for Post SP1 Driver updates for your computers Chipset.

the yellow mark on device manager means the driver has not been installed and the driver is connected to the motherboard use your motherboard drivers CD and install them or you can download them from the net

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.

Problem #1:
Please give more details about your setup -

• What kind of router are you using (make. model, version)?
• Do you have a wired or wireless connection from your computer to your router?
• By "resetting" do you mean to "repair" the connection via the taskbar?

Problem#2:

This is apparently a well-known bug in Vista, but nothing to worry about. Take a look at the information from Microsoft.

Please give more details regarding problem #1 and I'm happy to see if I can be of any help.

In the Control Panel, update the drivers. If still unsuccessful, delete those adapters, restart your workstation and reinstall drivers. Helpful to have another workstation nearby in case you need to download the drivers from the Internet.
