Quorum Error When Creating an AlwaysOn Availibility Group

I ran into the following error today when trying to create a new availability group for AlwaysOn.  This was on a fresh install of SQL 2012.

"The local node is not part of quorum and is therefore unable to process this operation. This may be due to one of the following reasons:

• The local node is not able to communicate with the WSFC cluster.

• No quorum set across the WSFC cluster.

For more information on recovering from quorum loss, refer to SQL Server Books Online."

To fix this issue, make sure you have the prerequisite hotfixes applied:
Prerequisites, Restrictions, and Recommendations for AlwaysOn Availability Groups (SQL Server)

In particular, this specific error requires hotfix 2494036.

If the error still comes up, disable and re-enable AlwaysOn in SQL Server Configuration Manager, then restart the SQL instance.
