I am not able to connect to the database engine. I have recently installed SQL Server 2012 after formatting my hard drive.
Operating system : Win 7 Enterprise 64-bit
When I try to connect to the database engine :
WN7X64-XXXXXXX, I get the following error message
A network-related or instance-specific error occured. Could not open connection to the SQL Server'.
I tried accessing using (localhost). It did not work.
I tried accessing using (localhost)/SQLExpress. It did not work.
I tried accessing using (localhost)/MSSQLServer. It did not work.
I tried accessing using MSSQLServer. It did not work.
When I checked the services. SQL Server status is starting, and it does not give me the option to start/stop. SQL Server Agent status is blank, when I start the service it gives
Error 1068 : dependency service or group failed to start.
Name Status Startup Type
SQL Full-text Filter Daemon Launcher (MSSQLSERVER) Started Automatic

SQL Server Agent (MSSQLSERVER) Automatic

I sometimes get SQL Server Express stuck in 'starting', in fact, just now, which is why I googled up this page. The solution is to kill the process and restart it.
Simplest way to do that is through Task Manager, which you can start by right clicking the Windows system tray (banner at the bottom of the screen where minised programs go). Processes tab, Sort processes by Name, find all beginning 'SQL...' and stop them.
To restart SQL Server right click the Windows Start button, start Control Panel, Administrative Tools, Services, scroll to all services starting 'SQL...', right click to refresh, and stop any that are running, then start the 'SQL Server' service, followed by any others that are set to Auto or Manual start.
I had the same issue and MSDN Documentation did not help. https://support.microsoft.com/en-us/kb/307288.
It was to do with that there was an orphan Sql related service i.e SqlWriter was hanging around. Go to task manager and killed it. Then the error went away.
To connect to a SQL Server default instance (not Express), you can use:
just a . (dot)
just a (local) (be aware: in round brackets)
just a localhost (be aware: NO brackets)
See the official MSDN documentation on Logging In to SQL Server for more details and explanations, and for even more options how to connect.
Try localhost or (local). Not (localhost).
I had the same issue . go to task manager , search for "SQL Server Windows NT" then end the task . after that , go to your services (Run services.msc) and restart your sql server instance .
Solution works for me in MSSQL Server express edition with Windows 10 environment .

I have been working on SQL server 2014. It was working fine. Today when i was trying to connect to server it is not connecting. It is showing this error.
This probably is the issue because Windows turn off some services to optimize the windows performance, You should Try this:
Search Services in your search bar and open it, Search for SQL Server Services from the list of services, right-click > start and try connecting to your SQL Server again. make sure they are running
start MSSQLSERVER service from SERVICES tab in CONTROL PANEL
provided you are typing right database credentials
Probably you might want to start SQL server using SQL server configuration Manager (you can find it directly from Start menu) or you can go to the path in your C Drive based on SQL server version
See link from Microsoft:https://learn.microsoft.com/en-us/sql/relational-databases/sql-server-configuration-manager?view=sql-server-2017
Trying to install Sitecore 7.1 on local machine but getting an error while attempting to connect to SQL Server. If I browse for a Database Server nothing comes up in the list. I have SQL Server 2012 installed and several databases that were created from Visual Studio. What am I missing to make the connection?
For some it may be a case of the SQL Server Service has stopped running. To turn it back on:
Open up Sql Server Configuration Manager.
Select SQL Server Services in the tree view on the left
In the Context Window on the right check to see if your SQL server service is turned off.
If it is right click and click start.
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've just started work on a new computer in which I had to download all the software fresh.
I've just download a copy of SQL Server 2008 R2, and I'm trying to connect to SQL Server Management Studio without success. I vaguely remember last time I installed this, it asked me to choose between windows, or sql server authentication, however this didn't happen for this installation.
If I try to login via Windows Authentication (where the username and password fields are greyed out, localhost as server name) it gives the following error:
"A Network-related or instance
specific error occured 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 have checked everything in SQL Server Configuration Manager, and everything bar VIA is enabled.
If I try SQL Server Authentication, It asks me for a username and password which I definiately have not set yet. Also, under SQL Server Services in configuration manager, there is nothing there.
Any help would be appreciated :)
Thanks
PS: I don't know if it's worth mentioning but I am running Windows 7 as a virtual machine on a Mac.
Are you sure you have the correct instance name? If it was SQL Server 2008 R2 Express Edition then the default instance name is .\SQLEXPRESS.
Also if your using sql authentication to connect try running sql management studio as admin, if you are a limited user your identity might not be mapped to an account in sql server yet but i believe the Administrators user group is.
You need to check if your services are running.
Please type
net start mssqlserver
in your command prompt. Then try to login.
Ended up reinstalling completely and doing a fresh install from a fresh download. When I did this I was brought through the steps of selecting the default instance, and selecting authentication modes.
Working fine now :)
After checking tons of sites looking for an answer to this question, I think I have a simple solution.
Open the sql Server Configuration
Click on the sql server services node
Right Click on Sql server
Click Start.
I have been screwing around with this forever, and this simple method actually worked.
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.
