I had this problem and was able to resolve -but i am not overly happy with the way i had to fix it ...
go to your hosts file and comment out the ::1 (the "::1" is use for the localhost for ipv6)
127.0.0.1 localhost
::1 localhost <--- comment out this line #::1
I am not sure if this is a vs2008 thing or a vista thing
if anyone finds out then please let me know
Pete
