Vista’s ISATAP Adapter Bug and How to Troubleshoot Similar Issues



If you have enough time at your disposal, exploring Vista is a pretty interesting experience, especially since you may bump into some strange problems, as I did. Since after a little research I discovered that the issue I encountered is a system bug, I decided to let you know more about it, too.

As you can see in the screenshot below, in my Device Manager I have an entry next to a yellow exclamation mark. This is the problem I was talking about, so let's see if you have it or not, first of all...
The error in Device Manager


The good part is that some computers don't have this problem, and discovering the truth takes only a minute.

- First of all, press the Start Orb, type "device" in the search bar, and then click the Device Manager.
Opening the Device Manager


- Expand the Network adapters section and see what you got there.
This is it


- If you have an entry like the one in the screenshot above, starting with "isatap", don't try to update driver or remove it, because after the next reboot this is going to be back.

For other similar problems, try to do the following things - update the existing driver, remove the device and then scan for hardware changes, and be sure to do some research on the Internet for your problem. If you noticed this ISATAP bug on your Vista computer too, please don't forget to drop us a comment!

Unfortunately, the only thing that can be done about it, at this time, is to ignore the error message, as there is no fix announced to be on the way, because Microsoft didn't bother to fix it since March, as you can see on the official support page...

    Hi! I had a simmilar problem and i formatted my drive and reinstalled VISTA but i can not see my Wireless adapter in the Device Manager and if i view device by the type (hidden device) then i get to see the isatap with the curly brakcets and an address the way it is mentioned up there! If i right click on isatap and get to see the properties it says the device is working properly and gives me a location unknown. i have tried to reinstall the drivers for my wireless but i feel like it is dead for some reason have not had a wireless device to check it with but the amber light on the compaq F572US that would change to blue is amber regardless.
