For what it's worth, we now have two examples of "Windows 7 Enterprise" 
(32-bit) systems which seem to have no problem at all accessing AFS after 
an address change (typically 2 minutes needed to re-establish access after 
a change).  We also have one example of "Windows 7 Professional" which 
clearly follows the pattern described above.

>From the published descriptions of differences between different versions 
on Windows 7, I could believe that the virtualization features of 
Enterprise might be responsible for the difference.  From the description, 
it seems that "Ultimate" stands a chance of working too, but I've got no 
Ultimate system to test on.
My guess is that all the home editions would also fail as above.

I also discovered that on Ultimate laptops using only secure wireless 
connections, this is a complete show stopper, since they boot with no 
network, and transition to a real address only after login and wireless 
authentication, and the loopback adaptor comes 'pre-hosed' to the login 
session.
