Sitting pretty in IPv4 land? Look, you're gonna have to talk to IPv6 at some stage

SBS 2011 switch off IPv6 and the following happens

•Microsoft Exchange services fail to start

•Server hangs at “Applying Computer Settings…” (can eventually logon after 30 – 60 minutes)

•Network icons show as offline

SBS 2011 uses IPv6 for internal communications

I can attest that Exchange running on a full server 2012 R2 install breaks horribly if you shut the IPv6 stack off. (and I do mean horribly. Plus, MS Support won't touch it until you turn it back on.)
