Hi,

I have exacty the same problem that is described here:

SYMPTOMS
On a Windows Vista-based computer, the Microsoft ISATAP adapter
appears with a yellow exclamation mark (!) next to it in Device
Manager. Additionally, when you open the properties dialog box for the
device, you receive an error message that resembles the following:
Windows cannot load driver (Code 31)
Back to the top

RESOLUTION
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.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft
products that are listed in the "Applies to" section.

Now, it's good, that the bug seems to be harmless, but the exclamation
mark in the device manager is really annoying.

Is a fix on the way?
