On a clustered Windows 2012 R2 server with SQL Server 2014 Enterprise.

Just upgraded an instance from 2014 SP1 CU4 to 2016 RTM and now getting this error when attempting to start the SQL Server Agent.

Windows Application Log

SQLServerAgent could not be started (reason: Unable to connect to server 'A08SQL-EDI\EDI'; SQLServerAgent cannot start).

The agent starts and runs for about 30 seconds then dies with the above error. Anyone run into this issue? And do you know how to resolve it?

ODBC issue for 13 version. please apply the 13.1

Problem resolved by adding an alias to the instance in the SQL Server Agent Configuration.

The alias was defined using the fully qualified domain name of the server. Example:servername.domain.biz\instance_name otherwise the agent will still error out and shutdown.

enter image description here

Also, the Agent was disabled in sp_configure

sp_configure 'Agent XPs', 1
go

reconfigure with override
go

So reenabled it.

    This is a work-around; the actual solution is Illidan-zhu's answer dba.stackexchange.com/a/152741/29371 , and/or a subsequent CU/SP update from MS, which I'm currently testing. – NateJ Jan 11 '17 at 1:17
  • CU2, CU3, and even SP1 still don't fix the problem. In fact, according to this article, SP1 overwrites the ODBC update (i.e. Illidan-zhu's answer). So, best bet is to ensure that, if using multiple named instances on a cluster, you keep that ODBC driver updated. – NateJ Jan 11 '17 at 21:00
