Cannot connect to local instance of SQL Server 2008 - sql

I'm attempting to connect to an instance of SQL Server 2008 (Developer Edition) in SQL Server Management Studio but am receiving the following error:
In SQL Server Configuraton Manager, all services are running and logged in as LocalSystem.
I have set the SQL Native client 10.0 configutarion to enable Shared Memory, TCP/IP, and Named Pipes. I have also set SQL Serer Network Configuration to enable Shared Memory.

The default (unnamed) instance uses MSSQLSERVER as its service name - so it seems your instance is actually called MSSQLSERVER08.
Therefore, you need to use
.\MSSQLSERVER08
or
(local)\MSSQLSERVER08
as your server name for connecting...
Note:
all these things refer to the local machine in the context of connecting to a SQL Server installed on that machine:
.
(local)
localhost
or your actual machine name (whatever it might be)

For SQL Express use .\MSSQLSERVER08 as your server name. Try to enable TCP/IP, Shared Memory and Named Pipes from all programs
Also check if the service is started:

Restart the SQL Server services. Then try to connect.
OR
If you have Installed SQL server with named instance, browse for for the server name.

Connecting to SQL Server Express - What is my server name?

I was just given a laptop to perform some development from a client and I am currently in the process of setting it up. Visual Studio 2010 is installed as well as SQL Server Management Studio 2008 R2. I'm trying to open SQL Server Management Studio to connect to the database but so far am not having much luck. I'm used typing in for a server name something like...
localhost
(local)
SQLEXPRESS
None of these are working.
So my question is: How can I tell what type of SQL Server installation and configuration I have on this machine, and how can I discover what server name I need to use in order to properly connect to it?
--Addition--------------------------------------------
I looked into the services as directed and found a few instances as indicated. SQLEXPRESS and MSSQLSERVER. I have tried to login with both of those options in these configurations...
SQLEXPRESS
MSSQLSERVER
computername\SQLEXPRESS
computername\MSSQLSERVER
.\SQLEXPRESS
.\MSSQLSERVER
None of these worked. I also altered the 'Log On As' property of the services from 'Network Service' to 'Local System' and tried them again. Still no success.
Instead of giving:
./SQLEXPRESS //in the Server Name
I put this:
.\SQLEXPRESS //which solved my problem
You should be able to see it in the Services panel. Look for a servicename like Sql Server (MSSQLSERVER). The name in the parentheses is your instance name.
If sql server is installed on your machine, you should check
Programs -> Microsoft SQL Server 20XX -> Configuration Tools -> SQL Server Configuration Manager -> SQL Server Services
You'll see "SQL Server (MSSQLSERVER)"
Programs -> Microsoft SQL Server 20XX -> Configuration Tools -> SQL Server Configuration Manager -> SQL Server Network Configuration -> Protocols for MSSQLSERVER -> TCP/IP
Make sure it's using port number 1433
If you want to see if the port is open and listening try this from your command prompt...
telnet 127.0.0.1 1433
And yes, SQL Express installs use localhost\SQLEXPRESS as the instance name by default.
Sometimes none of these would work for me. So I used to create a new web project in VS and select Authorization as "Individual User Accounts". I believe this work with some higher version of .NET Framework or something. But when you do this it will have your connection details. Mostly something like this
(LocalDb)\MSSQLLocalDB
by default -
you can also log in to sql express using server name as:
./SQLEXPRESS
or log in to sql server simply as
.
This was provided after installation of Sql Express 2019
Server=localhost\SQLEXPRESS;Database=master;Trusted_Connection=True;
So just use 'localhost\SQLEXPRESS' in server name and windows authentication worked for me.
Similar to what StuartLC was saying, my problem was not resolved until I enabled TCP/IP protocol under SQL Network Configuration>>Protocols for MSSQLSERVER in the SQL Server Configuration Manager dialogue box. After enabling this and a restart, my SSMS connected right away with just the instance name (no ~\MSSQLSERVER).
All of the following services should be running,for successful connectivity:
SQL Full test filter Daemon,
SQL server(SQLEXPRESS),
SQL Server Agent(SQLEXPRESS),
SQL Server Browser,
SQL server reporting service and
SQL Server VSS Writer

Cannot connect to localhost SQL Server 2005

I just installed SQL Server 2005 SP2 on Vista and am attempting to connect to my object explorer in Management Studio. When doing so I get the following error:
Cannot connect to localhost.
A network-related or instance-specific
error occurred while establishing a
connection to SQL Server. The server
was not found or was not accessible.
Verify that the instance name is
correct and that SQL Server is
configured to allow remote
connections. (provider: Named Pipes
Provider, error: 40 - Could not open a
connection to SQL Server) (Microsoft
SQL Server, Error: 2)
I am using the following credentials:
Server type: Database Engine; Server name: localhost; Authentication: Windows Authentication
I am just using SQL Server for a local application. I have tried using 127.0.0.1, my comp name, "." and localhost. I have searched and tried every relevant help topic I could find. I have reinstalled, turned on IIS (just a guess), updated to latest service packs all around, run as admin, etc.
What am I missing here?

Did you run the User Provisioning Tool for Vista? See KB929907 You may be unable to perform most database operations after you log on to an instance of SQL Server 2005 Express Edition Service Pack 1 on a Windows Vista-based computer
Try using (local)
Also if you have an instance name you can try myComputerName\instanceName
You're missing the instance name. You don't just connect to localhost, but to any of the following (assuming that your machine is called dago and your instance sqlexpress):
localhost\sqlexpress
dago\sqlexpress
.\sqlexpress
I am not using express. It turns out I had a "client" version of SQL Server installed. I didn't even know there was a client version. I ran the full install and added the sa user as Windows Authentication wasn't working for me (next goal). I am connecting via "localhost" (just localhost), so I don't fully understand what the instance suggestion was all about.
Basically the solution was to get the full version installed. My bad. Easy fix.

Unable to connect to SQL Server 2005

I am trying to connect to SQL Server 2005 express edition from SQL Server Management.
From the server configuration manager, I found the SQL Server Service to be running and within bracket, it's written(SQLEXPRESS). I understand SQLEXPRESS is the instance name, therefore I have to use following string for server name: \SQLEXPRESS.
I am using windows authentication. I am logged into an account that is non admin.
Can someone suggest me how I can establish the connection.
Thanks.
Try .\SQLEXPRESS..
From here:
By default, SQL Server Express
installs as an instance named
"SQLEXPRESS," for example. You connect
to a named instance by specifying the
instance name with the server name in
the connection string. That is why you
normally specify ".\SQLEXPRESS" as the
server name when connecting to a local
SQL Server Express database. The dot
means the local server and \SQLEXPRESS
specifies the SQLEXPRESS named
instance.

Connecting to a fresh SQL Server installation

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.

SQL SERVER 2005 Connectivity Problems

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].
