Please can you help me? I have a big problem with SQL server 2012 installed on the windows server 2012 :
I have three Databases on a named instance\BIOUGNACH2012SP1 and some time the end users try to connect to one of the three databases (for example to the first company: Biougnach équipement) but the connection failed, for the two other databases it's work correctly.

So I change just the IP address of the machine(end user) to a new one and when I try again the connection work correctly.
for more information :
- when the machine is blocked I ping on the server address and the ping work correctly.
- I have disable firewall on the windows server 2012.
- The application connected to 3 databases (3 company) in the same server and named instance.
- I use the same connection string in the application, I change just the database Name, I use the same user/password for the three databases.
Please Help me & Many thanks in advance.

I would add a SQL alias to the client computer, specifying the port that SQL is listening on (would mean you'd have to use a static port).

Oh and we need to see the error message.

it does not sound like a connection string issue. All 3 databases should respond to the same IP and Port.

Are using a SQL ID or Windows ID to connect. If it is a SQL ID, make sure it is not orphaned. That would do it.
