I have been told by people who know more about Windows than I do that 
if you disable IPv6, a large number of windows RPC things in Win7/Server2008 
will just stop working.  To quote "the *base* communication protocol in
W2k8R2 is IPv6, you just *can't* disable it".

See, for example, http://www.networkworld.com/community/node/45032
