Remote Access to SQL 2012 Instance

Hi,

I have a server with SQL 2000 on as a default instance, and I can successfully access this remotely.

I have now added an additional install of SQL 2012 as a named instance, but I cannot work out how to access this remotely from SSMS.

I have tried connecting to <Server Address>\<Instance Name> but I cannot.

I have checked that the SQL Browser service is running.

I have opened UDP port 1434 on both Windows Firewall and the external firewall.

What do I do next?

What message are you getting when you try to connect? Is it simply not finding the server, or is it something else?

Try connecting to the IP/Port with telnet. That will at least tell you if the server is listening on the right port.

Error attached.

Do you mean telnet to port 1434, that says connect failed.

Start with the basics then. Open up the Configuration Manager for SQL 2012, on the server where it is installed, and check what port it is configured to run on.

Also check that the TCP protocol is enabled and that it will allow remote connections (although the latter doesn't sound like the issue, as it appears you can't even reach the server).

I have looked in both "SQL Native Client 11.0 Configuration (32 bit)" and "SQL Native Client 11.0 Configuration" and in each case the port was 1433.

This obviously clashes with SQL 2000 on the same server, so I tried changing both of these to 11433.

I then restarted the 2012 SQL instance and tried connecting to "local host,11433" using the local SSMS but this wouldn't connect.

From SSMS you will need to specify the port and instance name when connecting:

     <Server>\<InstanceName>,11433


What happens if you telnet to your the server on port 11433?

<server>\V2012,11433 does not work locally!

I had this issue. You need a newer install of SSMS, specifically 2012 or later. Make sure to keep your older one around also, as communicating with older servers, like that sql server 2000 can be problematic.
