Hi

i've 6 instances , each one with unique parameters.

I mean :

I1 DAG1 Listener1 listener_IP1 Listener_port 1433

I2 DAG2 Listener2 listener_IP2 Listener_port 1434

I3 DAG3 Listener3 listener_IP3 Listener_port 1435

I4 DAG4 Listener4 listener_IP4 Listener_port...

Sure !

I've 6 instances, each one with a dag and unique listener name , unique ip and unique port number but when i use only the listener name to connect,...

You're right

If i only give the listener name, it's toward the listener designed with the port 1433 that it's really transmit... the port of the listener of the first instance...

There are several instances on the server but the sql account i use has been created just now ; just for the purpose of this test

Created on node1 instance1 then...

Hi

Error Number: 18456
