Microsoft ISATAP adapter 6to4 & no 3

The above two adapters are showing a yellow warning in Device Manager.

I have searched for an update but they are the latest drivers.

From the net it appears that this is one of those vista gremlins and that there is no real problem.

Some folk have disabled them with no apparent setback.

Others have noticed a change and have re-enabled them.

Any thoughts out there.
