the pre-login handshake

Posted on 2014-03-24
Last Modified: 2014-09-22
I have been getting this same error a few times. All my code does is calling a store procedure and have it returns somedata.  Any thoughts on this error?

System.Data.SqlClient.SqlException (0x80131904): Connection Timeout Expired.  The timeout period elapsed while attempting to consume the pre-login handshake acknowledgement.  This could be because the pre-login handshake failed or the server was unable to respond back in time.  The duration spent while attempting to connect to this server was - [Pre-Login] initialization=16360; handshake=6680;  ---> System.ComponentModel.Win32Exception (0x80004005): The wait operation timed out
   at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 wrapCloseInAction)

Is it just sporadic or all the time?
Is port 1443 open on the servers firewall?
Is IPv6 enabled

Is there anything else bogging the server down?
Are you running long queries?
Is the DB getting locked?
