ODBC connection for testing Availability Group Listener I am having difficulty verifying my Availability Group Listener configuration.  I would like to create an ODBC connection which points to the listener.  When I configure the system DSN and try to test the connection at the end, I get timeout errors.  However, when I change the server to point to the instance name instead of the listener name, the connection works.  How can I test the listener using ODBC? What other method can I use to test the listener?  

Note: I do not have access to an application to test client connectivity.
Converting my comment to answer :

You can use SQLCMD.exe -S &lt;AG listener&gt; -D &lt;AG database&gt; -E. 

You may want to specify AGlistener,port_no to see if you can connect to the listener.
