I'm not sure. As I understand it, Vista has a problem if it gets a 
ping just after it gets the address via DHCP. The ISC does the ping 
before making an offer. I would expect the ping to arrive before the 
offer, and so it shouldn't be triggered.

I have to say though, it never ceases to amaze at how imaginative 
people can be when creating bugs !
