Remember to Enable IPv6 With Exchange 2010

As the title says.  Remember to enable IPv6 when using Exchange 2010.

After powering on my Exchange 2010 servers after a power outage, I found that a few Exchange services wouldn't start on the Hub Transport/Client Access server.

After a few reboots and running some diagnostics.  I decided to build a backup server that I had.  I received the following error while installing Exchange 2010 SP2:

After doing some research I found that Exchange 2010 requires IPv6 to be enabled and that a IPv6 address (unique-local) must be assigned to interfaces on all servers.  After doing this, all of the services that failed to start on the original Hub Transport/Client Access server started without an issue.
