Here is the scenario I am facing.
I have installed Windows 7 Professional on a VMWare.
Installed SQL Server 2008 R2.
When I launch the Server Management Studio and try to connect to the instance I get the following 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)
(Microsoft SQL Server, Error: 53)"
Now, I installed all the packages of SQL server with default settings. The only change that I had done is selected a mix-mode for authentication.
I setup a similar instance on a desktop and it works fine. Before posting it here I have searched on the web and made sure all the services, ports and protocols are enabled/running.
But I still cannot seem to connect, any help?
Ok, so finally found the solution the above mentioned problem. Not sure why, but when I give the instance name pre-appended with .\ it works fine.
.\<INSTANCENAME>
You may not have a default instance installed?

I have just installed SQL Server 2016 (Developer Edition) database engine on my dev machine (Windows 10).
When installing I named the instance CUBE, with Windows authentication using the current (only) user's credentials.
I can see the instance running in Services:
When I try to login using SQL Management Studio I get the following 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...
Things I've tried:
Checked the server is running (it is)
Opened firewall port 1433 (no difference)
In SQL Server Configuration Manager > SQL Server Network Configuration I've enabled Named Pipes and TCP/IP
I can't see what I'm doing wrong - can anyone help?
Make sure that the MSSQLSERVER service is running, you can check the following article from microsoft on how to manipulate the MSSQLSERVER Service.
Start, Stop, Pause, Resume, Restart the Database Engine, SQL Server Agent, or SQL Server Browser Service
finally, take a look to the following post it might help you:
Why am I getting "Cannot Connect to Server - A network-related or instance-specific error"?
I am currently running Visual Studio Web Express 2013 with SQL Server 2014 Express. Recently, I finished installing the sql server and tried to create a model by connecting the sql server. I received this message :
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 Provide, error:40 - Could not open a connection to SQL Server)
The time I installed I still can see the Server Name under Data Connection > Add Connection in Visual Studio but the message appeared and no database in the list shown. Later, don't know what I did, I can't even see the Server Name in the same dialog.
A list of installation here:
Does anyone know what is going on and how I can fix it?
First you need to check name of your local server. You can know that by going in sql server configuration manager n see the name of server there.
See in picture name of server is SQLEXPRESS
so my login is .\[SQLEXPRESS]
If there is no server available you need to install again.
I'm trying to connect from a local SQL Server Management Studio to a SQL Server hosted in a VM on Azure.
I followed all the instructions from
http://www.windowsazure.com/en-us/manage/windows/common-tasks/install-sql-server/ and created the necessary endpoints:
Somehow, I can't connect to the SQL Server, getting this error
Cannot connect to xxx.cloudapp.net.
ADDITIONAL INFORMATION:
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: 53)
The network path was not found
I already tried to temporary disable the windows firewall on the vm - without success. Any suggestions?
I had the same problem, this troubleshot helped me getting close to the solution:
Use SQL Server Management Studio to connect remotely to an SQL Server Express instance hosted on an Azure Virtual Machine
Summing up, what i did, i don't know if all these steps are necessary, so you should test after each one:
1) In SQL Server configuration manager enable Named Pipes in protocols
2) In the VM add a windows firewall inbound rule for sql server port (in my case the default 1433, in yours it seems to be 1435, make sure it's 1435 in sql server configuration)
3) Make Sure you are using a sql server authentication login (not a windows authentication) if you don't have one create it locally in the VM>MSSMS
4) Make Sure the SQL server is configured for mixed authentication (http://www.katieandemil.com/microsoft-sql-server-error-18456-login-failed-for-user)
5) Make sure sql server browser is running
Hope this helps :)
I installed SQLManagementStudio_x64_ENU from Microsoft site on my Windows 7 Home Premium.
It gave me compatibility warnings but I still installed because Microsoft site specified that I would receive warnings but suggested to click on Run Program, which I did.
It was successfully installed. I checked Services.msc, and I can see two SQL Server services are running. I checked SQL Server Configuration, and I can see services running under automatic mode, and the agent is off.
When I open my management studio and try to connect using "Server name" option, I can't see any server instance in browse option. There are no servers to connect. I am not able to connect to the database engine. I have tried at least 10 times, but still, it's not allowing me to connect.
I get the following error:
A network-related or instance-specific error occurred while establishing a
connectionto 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)
Can someone help me with this problem?
In the Connect to server dialog of the SQL Server Management Studio (SSMS), type <your machine name>\SQLServer2008 to connect to SQLServer2008 instance. Otherwise, type <your machine name> alone in the server name text box to connect to the default instance SQLExpress.

I have SQL Server 2008 R2 installed on my PC running Win 7 x64. I used to use it every day with a connection from management studio (Windows Authentication). But, for some reason, management studio is not accepting my connection anymore after I installed DB2 on the same PC.
I know that the instance is not broken since I am able to connect well with Visual Studio 2010 where I also tried creating new DB, inserting records etc.
How do I mend this problem with management studio? How might installing DB2 have affected Management Studio?
I am getting following error:
TITLE: Browse Server for Database

establishing a connection to SQL Server. The server was not found or

SQL Server is configured to allow remote connections. (provider: SQL

It's not an authentication issue, as you would get a different error. If this is a named instance, you need to ensure the SQL Server Browser service is started.
I'm guessing you also have TCP/IP protocol enabled?
I don't know much about DB2 but maybe there is some conflict with the ports used. By default SQL Server uses 1433 for the default instance, and 1434 for SQL Browser to dynamically allocate a port for named instances. Check these to make sure they are still good.
Make sure that you have port opened on target server.
Use Telnet (install from Control Panel -> Turn Windows features On of Off)
>telnet <server-ip/name> 1433
or network scanner from nmap.org
>nmap -sT -r -n -vv -p1433 <server-ip/name>
