Thanks for confirming that behavior.  Sean Siler, Microsoft's IPv6 person
who follows this list, is checking on this as well and hopes to report back
on this in a few days.  My google-fu is coming up with nothing online, but I
find it surprising that no one has reported this discrepancy until now.

The beta versions of Win2008 R2 did this as well.  Don't know if it was
changed in the final release.
