On our development server we have three versions of SQL Server installed (SQLEXPRESS 08, SQL2008 R2, and SQL 2012).
In the services, I can see the following instances:
SQL Server (MSSQLSERVER)
SQL Server (SQLEXPRESS)
SQL Server (SQL2008)
When I open all three servers in SQL Mgmt Studio and connect to all three servers, I see the following names for the servers:
(local) (SQL Server 11.0.3128 - OBX1\Administrator)
(local)\SQLEXPRESS (SQL Server 10.50.2500 - OBX1\Administrator)
(local)\SQL2008 (SQL Server 10.50.2500 - OBX1\Administrator)
When I connect to the server at the IP address or server URL, it connects to the the SQLEXPRESS instance but I need to connect the 2012 instance, which is the at (local) (SQL Server 11.0.3128 - OBX1\Administrator).
No matter what I try, I can't get connected to any instance besides the default one, which for some reason seems to be SQLEXPRESS.
Looking for an example of the proper connection value for the other instances??
Screenshot below:
If I RDP to the server and open up SQL Mgmt Studio I have three options for servers to connect to, (local), (local)\SQL2008, (local)\SQLEXPRESS. If I select (local) and run the command to get servername and version I get OBX1 for the name and 2012 for the version. If I select (local)\SQL2008 and run the same commands I get OBX1\SQL2008 and SQL Server 2008 R2(sp1) and if I select (local)\SQLEXPRESS and run the command I get OBX1\SQLEXPRESS and SQL Server 2008 R2 (SP1).
Given this addition info, how do I connect the instance that is just (local) remotely with the IP Address? Is this possible?
Again, currently if I connect remotely at the_ip_address it connects to the SQLEXPRESS instance. And if I try to connect to, for example the SQLEXPRESS instance like so, the_ip_address\SQLEXPRESS it connects to the SQLEXPRESS instance again.
Duplciate of this: https://serverfault.com/questions/104922/sql-server-connection-string-question
To connect to a named SQL Server instance, you can:
Specify the server (machine) name and instance name in the connect string:
Server=myServerName\myInstanceName;Database=myDataBase;Trusted_Connection=True;
specify the specific port and either the server (machine) name or IP address:
Server=myServerName,1437;Database=myDataBase;Trusted_Connection=True;
Server=123.98.76.45,1437;Database=myDataBase;Trusted_Connection=True;
Note: Specifying port 1433 will [usually] get you the default, unnamed SQL Server instance on the machine (but not always as it depends on how SQL Server has been installed and configured). Note also that specifying an explicit port and and instance name makes no sense whatsoever.
And when in doubt, visit http://www.connectionstrings.com/ for pretty much any database out there [though connecting/configuring Oracle connections is its own peculiar form of hell].
You might need to identify and subsequently specify the portnumber as well. Ie:
tcp:MyServer,7701
tcp:MyServer,7704
Note that the portnumbers above are from one of my installations - yours may very well be different.
To identify the portnumbers, go to the SQL Server Configuration Manager and look under SQL Server Network Configuration. You should see separate entries for your instances here, and the properties for each instance should include a TCP Port or Dynamic Port or similar.
This answer may be useful.
You should enable the SQL Browser service, but it is most likely running. Also ensure TCP protocol is enabled for each service using SQL Server Configuration Manager application found in the SQL Server program group. You will find these settings under SQL Server Network Configuration. Some versions of SQL have TCP/IP disabled by default.
I'm not sure if the 2012 SQL Server configuration will see the other instances, so you may have to make the change in multiple places. I'd start in the 2012 Config Manager.
Specifying a port number when an instance is set up to use dynamic ports is probably not a good idea.
Some applications require you to set a static port - typical with JDBC apps.
If you're still having issues, check into firewalls. Portqry and telnet can help test connectivity.

I have a database alias made using SQL Server Configuration Manager.
Here is what I done:
I've made an alias named "FCIS.SIS" for both 32-bit and 64 bit configurations with port number 1437.
TCP/IP enabled.
TCP/IP properties IPALL port 1437.
Both SQL Server (MSSQLSERVER) and SQL Server Browser services have been restarted.
Here is what I get:
I'm using SQL Server 2012 on windows 7
Also I've tried every single solution mentioned in this question but nothing worked for me.
I installed SQL Server 2012 on Windows server 2012, I can connect to the server only if I write . in the server name field.
But I can't connect using the server name MSSQLSERVER.
I am trying to connect using SQL Server Management Studio from the same machine.
I checked that TCP/IP is enabled, IP2 is enabled, port 1433 is configured for all IPs, added an inbound rule for port 1433.
Also tried restarting both the SQL Server service and SQL Server browser service multiple times, but no luck.
Any ideas on what could be causing this problem?
Wow, this is an old post. Still I'm going try to answer this just in case someone else is wondering.
The Short Answer
MSSQLSERVER is typically not used as the name of a Server hosting the SQL Server Object (often referred to as SQL Server). Since you are using SSMS, you need simply define the name of the SQL Host--the actual NetBIOS name, or FQDN, or IP address of the host.
If no instance was created during installation
Server Name: ServerHostName
If an instance was created during installation
Server Name: ServerHostName\InstanceName
or IP address
Server Name: ###.###.###.###\InstanceName
If a port was defined other than the default port of 1433
Server Name: ServerHostName,####\InstanceName
The Long Answer
First a question. Is the MSSQLSERVER the actual NetBIOS name of your server? When talking about a SQL Server, it can be a little confusing at times as the name SQL Server is used to describe the host as well as the SQL Server Object (which is what most people are referring to in this context).
When using a tool like SSMS to connect to the SQL Server, you are first connecting to the host server, and once connected, you will connect to the SQL Object itself. The "." is not an object, or is not a valid SQL server name, unless you named your SQL server ".".
Regarding the instance, this is usually defined during the installation of the SQL Server (the object). Post installation, if you forget or simply do not know the name of the instance, the fastest way to determine what the instance name of your SQL server object is, is by checking system Services.
services.msc
Take a look at the SQL Services that are running. If you created a SQL instance during the installation of the SQL server object, then the instance name will be in (): i.e. (SQLInstance). On the same token, if you create multiple instances on the same server, then you will see multiple service names like,
Default Instance
SQL Server
With Instances
SQL Server (SQLInstance1)
SQL Server (SQLInstance2)
That should answer an issue where you can connect to one instance, but not another if one instance is running but the other is not.
If you did not create a SQL instance during installation, then the default SQL instance will always be MSSQLSERVER, and you will not need to define this in the Server Name spot of the SSMS.
I hope this helps.
It's a typical problem.
Just use cliconfg.exe to create alias with tcp/ip protocol.
If unsure do the same alias for 32 and 64 bit.
The 64 bit version is found in:
C:\Windows\System32
The 32 bit version is in:
C:\Windows\SysWOW64
In General tab enable TCP/IP.
In Alias, create a new alias, insert the name you prefer (with named istance) and select TCP/IP as network libraries.
As server name put the ip and 1433 as port. Don't leave "dynamicaly determine port" selected.

Try to enable the SQL Browser service.
The port number in SQL named instance is dynamic
SQL Brower uses UDP port 1434 to send the correct TCP port to the client.
If your SQL server instance is a default instance, you can login with the following as the Server name:
. (period)
LAPTOP-JDRDGF9T (the name of your PC)
localhost
127.0.0.1
If it on the other hand is a named instance, you login with localhost\<INSTANCE_NAME>, instance name normally being SQLEXPRESS.
You can Go to SQL Server Configuration manager >> SQL Server Network Configuration >> Protocol for MSSQLSERVER
OR
SQL Native Client configuration >> Client Protocols
In the right pane split page you will have to enable and disable the followings:
>> Shared Memory Enable this
>> Named Pipes Enable this
>> TCP/IP Enable this
>> VIA Disable this
Also, Check whether you have checked the Mixed mode authentication or not.
I know mysql, and I'd like to learn sqlserver.
I'm currently stuck on the basics of basics:
How to install and configure sql server
How to connect to it
I installed Sql Server through Web Platform Installer, and have Visual Studio 2008 installed. Still, I can't understand how to connect to my server:
I see that the SQL service itself (SQLEXPRESS) is running in both in services.msc and Sql Server Configuration Manager
I try to connect to it via the Management Studio, but I don't understand what to do.
Where do I begin?
Start Management Studio and Select Database Engine as your SqlExpress instance then choose Windows Authentication and press connect. After that in object explorer you will see your databases if you want to create one right click databases and create new one.
You can look at http://msdn.microsoft.com/en-us/library/ms186312.aspx
There are two types of ways you can install a SQL Server instance:
1. Named Instance
2. Default Instance
When you use the default instance, and it's the only instance on the machine, the server would listen directly on the port 1433 which is the default SQL Server port. This is what you'd expect if you come from a mysql background.
When you "name" an instance, such as SQLEXPRESS, it works differently. You connect to a special service (SQL Server Browser Service) which now listens on that port, and points the client to the "correct" port of the named instance. I hope I'm being accurate about this one, but that's what happens in general.
You could connect directly to the named instance if you see what port it binds to in the SQL Server error log, and if you could choose the port in the client application.

i am connecting to sql server 2000 on a remote computer with a dotnet application, but when i try to open the connection it gives the following error:
When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections
What is this?
It means that the remote SQL server is configured to not allow remote connections.
From this forum discussion:
Make sure SQL SERVER is up and the instance you try to connect is running.
Your system Firewall should not block SQL Server port.
Go to Computer Management >> Service and Application >> SQL Server 2005 Configuration >> Network Configuration Enable TCP/IP protocol. Make sure that SQL SERVER port is by Default 1433.
Now follow this KB Article of MSDN depending on your server.
Are you sure you're connecting to a sql server 2000 instance?
Possibly it's been upgraded to 2005?
Try following the procedure here: http://support.microsoft.com/kb/914277 to allow remote connections.
By default, as a security feature, SQL Server 2005 does not enable connections from other machines on the network.
Verify that your SQL Server and its databases are suitably secured (for example, have proper user accounts and passwords, etc.). Once you are satisfied, go to Start, Program Files, Microsoft SQL Server 2005, Configuration Tools, SQL Server Surface Area Configuration. Look for Database Engine, Remote Connections and change the setting to allow remote connections.
I am having a hell of a time trying to connect to the SQL SERVER 2005 database. I am using Windows 7.
Here is the screenshot of the error thrown:
(source: highoncoding.com)
I have been battling this issue for the past week and still no progress.
I have tried the following in the server name:
(local)
localhost
computername
none of them worked!
I just checked in the services section and SQLSERVER EXPRESS is not even there. I am using the following post as a reference:
https://serverfault.com/questions/11745/i-cannot-connect-to-my-local-sql-server-2008
This instance of SQL Server is running on the same PC you're connecting from? That's the implication of 'local'.
Possibilities :
1) Try (local) instead of local for the server name
2) Try 'MSSQLSERVER' as the name
3) Check the SQL Server Configuration Manager shows the same configuration options you're attempting to connect with, eg the same instance name, Named Pipes enabled, services running ok, etc.
EDIT :
Ok, what are you using to connect with? SQL Server Management Studio Express? Are you sure you installed an instance? The lack of SQLExpress in the services list would seem to indicate otherwise.
When you connect to a SQL Server you specify the name in the form {computername}\{instancename}. The {instancename} is the name of the SQL instance which was chosen during the SQL Server installation. For {computername} you can substitute the special names . or local when connecting to the localhost machine. If the SQL Server was installed as the Default instance then the instance name part must be omitted, so the connection Server name becomes just the computer name.
SQL Server Express installs by default an instance named SQLEXPRESS. The corresponding NT service name is MSSQL$SQLEXPRESS. The Server name in the connection dialog is .\SQLEXPRESS, local\SQLEXPRESS, localhost\SQLEXPRESS or {computername}\SQLEXPRESS (they're all the same).
If the SQL Server was installed as the Default instance name then the corresponding NT service name is MSSQLSERVER. The Server name in the connection dialog is ., local, localhost or {computername} (they're all the same).
If the SQL Server was installed as a named instance then the corresponding NT service name is MSSQL${INSTANCENAME}. The Server name in the connection dialog is .\{INSTANCENAME}, local\{INSTANCENAME}, localhost\{INSTANCENAME} or {computername}\{INSTANCENAME} (they're all the same).
When connecting from a remote computer to a SQL Server instance the SQL has to be configured to allow remote connection How to configure SQL Server 2005 to allow remote connections.
Check your SQL server configuration, make sure the TCP connections are enabled. You can also check that the SQL Browser service is started. Make sure you do not have a firewall that gets on the way. Make sure the SQL Server service is also started.
Did you install SQL Server on the default instance, or have you used named instances? If you've used named instances then the server will be server\instancename. If you don't know, then have a look in the Services administrative tool; you'll be able to determine the instance name, if any, from there).
You could also try connecting with the server name as a single period (i.e. simply ".") [caveat... I've not got access to SQL Server at the moment, but I think I've used this before now].
