I'm having an issue with SQL Server, I have 2005 installed on my desktop as well as having SQL Server Management Studio installed..
I've checked and can see "SQL Server (SQLEXPRESS)" started in services.
I've tried to connect to "Local" and "SQLEXPRESS" but both fail to connect.
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) (.Net
SqlClient Data Provider)
Anything else I need to do to connect to it??
UPDATE
I seem to be getting a little further along now. Ive managed to connect to my server with SQL Server Management (FYI .\SQLEXPRESS did the trick) but now im having a issue with my connection string in my web.config
Ive im going to connect to this local sql server using windows authentication how do i need to structure it??
Something like this?
<add name="BensBoxing" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=BritBoxing_Alpha;Integrated Security=False;User Instance=True" providerName="System.Data.SqlClient"/>
This produces a error about
Login failed for user ''.
Check the sql log in the LOG directory of your instance - see if anything is going on there. You'll need to stop the service to open the log - or restart and you can read the old one - named with .1 on the end.
With the error you're getting, you need to enable TCP/IP or Named pipes for named connections. Shared memory connection should work, but you seem to not be using that. Are you trying to connect through SSMS?
In my log I see entries like this...
Server local connection provider is ready to accept connection on [\\.\pipe\mssql$sqlexpress\sql\query ]
As the comments said, .\SQLEXPRESS should work. Also worstationName\SQLEXPRESS will work.
Same as matt said. The "SQL Server(SQLEXPRESS)" was stopped. Enabled it by opening Control Panel > Administrative Tools > Services, right-clicking on the "SQL Server(SQLEXPRESS)" service and selecting "Start" from the available options.
Could connect fine after that.
I was having this problem on a Windows 7 (64 bit) after a power outage. The SQLEXPRESS service was not started even though is status was set to 'Automatic' and the mahine had been rebooted several times. Had to start the service manually.
Try to see, if the service "SQL Server (MSSQLSERVER)" it's started, this solved my problem.
Open Sql server 2014 Configuration Manager.
Click Sql server services and start the sql server service if it is stopped
Then click Check SQL server Network Configuration for TCP/IP Enabled
then restart the sql server management studio (SSMS)
and connect your local database engine

I am using Windows-server-2008 with Microsoft SQL Server 2008.
And there are a lot of questions about this, but nothing on the internet solved it.
The problem is that i can't connect to the my SQL Server 2008 R2 after rebooting my server.
I placed some new memory in my server, and after rebooting my client/server application didn't work anymore because it cannot reach the database.
So i tried to get in SQL Server Management Studio (SSMS), and tried to loggin with Administrator and another user but both do not work.
When i logg in the following message is displayed:
Cannot connect to (local)
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 Tried a lot of different things like:
Rebooting server
Try to start the server manually from Sql Server Configuration Manager
Named Pipes - Enabled
TCP/IP - Enabled
Tried to create an new system user or database user as described in the following article: Click Here
Can somebody please help me? I am really confused because i need to get this online. Otherwise i have to reinstall the database server but i do not have a back-up. (is there some folder with a back-up of the settings/tables/columns are stored and can be imported from reinstall?
I was having the exact same problem. net start mssqlserver was giving me the blurb about a failed login attempt. The problem was that I had recently changed the password for the administrator account, and the new password didn't get updated in services.
Here's how I fixed it:
First locate SQL Server from the list here:
Right click and select properties, and navigate to the Log On tab:
Then I typed the new password, and like magic I was able to start SQL Server right through the services manager.
I also did this for any other processes which were marked as "stopped" even though Startup Type was marked as "automatic" (namely, SQL Server Agent).
Is it a named instance or default? Also, is this a local instance? (I see the "(local)" but just wanted to make sure.)
Start the sql server services from services.msc and try to connect
I might be the million'th person posting about this, but others' solutions haven't helped me. I have a database on Microsoft SQL Azure. I an trying to connect to it using the Visual Studio 2010's "Connect to Database" Tool.
From my Windows 7 machine, I can connect to it very easily. But from my Windows Server 2008R2 machine i am getting the classic error -
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)
All the posts around the web seem to be focussing on the problems on the server side, no one cares if the client goes rogue. :(
Thanks for the replies.
I have seen similar problems with VS2010 DB Tool and Windows Server so I would not suggest try using SSMS 2008 R2 (must be R2). Once you have download SSMS 2008 R2 and configured properly to work on Windows Server it sure will work. In most of the case you really need to open SSMS settings to get it workon on Windows Server.
Next a few points to check:
Verify that the telnet is working from your Windows Server Machine:
c:>telnet _your_sqlazure_database_name.database.windows.net 1433
Disable your real time security and the try again
Finally following the link to keep applying settings in your Windows Server and SSMS which are applicable and I am sure it will work:
http://www.mssqltips.com/sqlservertip/2340/resolving-could-not-open-a-connection-to-sql-server-errors/
One issue is that you need to connect via tcp, not named pipes (per your error message).
Are both servers behind the same firewall (e.g. the same external IP address)? The SQL Azure firewall needs to be configured to allow access from remote IP addresses.
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

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

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.

I installed Microsoft SQL Server 2005 Express edition on my Vista Ultimate computer. However, when it opens I enter my computer name / SQLEXPRESS. When I click the Connect button, it gives me an error message.
Under the configuration tools I cannot find the SQL Server Surface Area Configuration. It only has SQL Server Error and Usage Reporting.
The error message I receive when I click the Connect button is:
A network related or instance specific error occurred while establsihing a connection to SQL server. The server was not found or was not accessible. Verify that the instance name is correct and that the SQL server is confugured to allow remote connection (provider: Named Pipes Provider, error 40- Could not open a connection to SQL Server) (Microsoft SQL Server : error 67)
From your question, as you'd written, it appears the slash is incorrect. Try:
.\SQLEXPRESS
Also ensure that your SQL Server services are started. Run services.msc and find SQL Server(SQLExpress).
Another thing to check for is the account that the SQL Express service is running under. I think it defaults to network service, but I typically run it under Local System (or if you're feeling ambitious, make a service account for it). This has taken care of a handful of permission issues I've had with SQL Express in the past.
I'm trying to connect to a remote SQL Server 2005 db from a .NET Windows service running in Vista Home Premium x64. I can access the remote db from a console app with no problem. I can connect to a local db from the Windows service with no problem. I was able to connect from a service from XP with no problem. There's no firewall or anti-virus running. How do I configure this service to be able to connect to the remote db?
I've tried to connect by running the Windows service as a local admin account, LocalSystem, LocalService, and NetworkService.
The connection string:
Data source=SERVER_NAME;Initial Catalog=DB_NAME;Integrated Security=True;
The error:
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)
MORE INFO:
I have also tried to connect using SQL Server authentication with no success:
Data Source=SERVER_NAME;User ID=USER_ID;Password=PWD;Initial Catalog=DB_NAME
This connection string works from the console app too.
MORE INFO:
I ran Process Monitor for the Windows Service and the console app. The Windows service showed \SERVER_NAME\pipe\sql\query was ACCESS DENIED but the console app showed SUCCESS when reading/writing files to \SERVER_NAME\pipe\sql\query.
Good Lord! Why all the gibberish and complex responses on this site. Create a User Account
Either local or Domain and set the service to use that account. Then go into your SQL Server and Add you new account to the Database and set permissions. Voila!
Oh yeah, dont plague yourself with SQL Authentication. Integrated Security is much easier to maintain and without a password in your web.config your much safer.
1) open a command prompt. Type "ping SERVER_NAME". Does it respond? You may have a DNS or connectivity issue if this doesn't work.
2) "telnet SERVER_NAME 1443". Do you see anything or does it refuse your connection? This will definitively tell you whether or not someone is listening on the other end.
3) Go into SQL Server Management Studio. Right click Properties of your server. Select "Connections" from the left side. Is "Allow Remote Connections" checked?
4) Since you're running using network service/system, you will need to make sure you have a login configured on your server for the machine account DOMAIN\CLIENTSYSTEMNAME$. Note the $ sign. This is your machine account, and this will be the user that SQL Server will see.
