Hello I'm trying to connect to SQL server with Microsoft SQL server management studio. However when I try to connect I get the following error:
Cannot connect to DESKTOP-QELGJNT.
===================================
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)

Error Number: 2
Severity: 20
State: 0
Usually you have to set up a server first before you can connect. How can I do this with SQL server management studio, if this is the reason I get this error.
I also checked under services but I couldn't click start on SQL server vss writer. That is the only sql file running I found.
I checked on YouTube and stackoverflow on a similar subject, however it didn't provide the solution for me. Could anyone help me?
This question can be helpful to others as well who have similar problems with SQL server management studio.
Is your SQL Server installed on your local computer? If yes.
Check your SQL Server Configuration Manager. If SQL Server service is in Running state.
It may possible your SQL Server service for that instance is stopped. There can be may reason one is due to service conflict with other. What you can do is
go to SQL Server Configuration Manager (type on start menu it will appear)
On left pan go to SQL Server Services
SQL Server() is running if not right click and start
If this will not resolve the issue then do check TCP/IP is enabled or not?
To enabled that
Open SQL Server Configuration Manager.
In the left pane, expand SQL Server Network Configuration, and then
click Protocols for MSSQLSERVER.
In the right pane, right-click TCP/IP, and then select Enable.
Double-click TCP/IP. The TCP/IP Properties dialog box is displayed.
On the IP Addresses tab, identify the block corresponding to the IP
address that you want to enable.
In the Enabled field, select Yes.
In the TCP Port field, enter 1433.
Click OK.

I get this 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: SQL Network Interfaces, error: 26, - Error Locating Server/Instance Specific) (Microsoft SQL Server)
I am trying to allow remote access to my local SQL Server database when the user is using my application on a different computer. I've been trying different approaches for weeks and nothing seems to work.
Here is a list of things that I have tried to do:
Changed server property settings to Allow remote connections to the server
Enable TCP/IP and listed 1433 port number in IPALL field
Created inbound rule for SQL Server program, SQL Browser, and port 1433
Temporarily disabled Windows firewall
Again, I know there is a lot of information surrounding this issue, but I feel like I've implemented every solution I could find and nothing is working.
Thank you in advance for your help!
Regarding #1, the allow remote connections to this server checkbox in SSMS does not actually allow remote client clients to connect despite the misleading name. Use SQL Server Configuration Manager (e.g. C:\Windows\SysWOW64\SQLServerManager15.msc, depending on your SQL version) instead. Right-click on SQL Server Network Configuration-->Protocols-->TCP/IP, select Enable, and restart the SQL Server service.
I am trying to create a connection manager in Microsoft SQL Server Data Tools for Visual Studio 2017 (SSDT) for an integration services project.
In the Connection Manager:
The Provider is set to: Native OLE DB\SQL Server Naive Client 11.0
The Server name is set to: the name of the local machine
Log on to the server is set to: Windows Authentication
Connect to a database is set to: Select or enter a database name. However no database names appear in the drop down box - the drop down box is blank. I am expecting the name of the database i am working on, including the master database etc to be present.
When I Test Connection, I get an error message which says:
'Test connection failed because of an error in initializing provider. Login timeout expired
A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online.
Named Pipes Provider: Could not open a connection to SQL Server [2]..'
I am using SQL Server 2017 and Microsoft SQL Server Management Studio 18.
Allow remote connections has been ticked in SSMS.
The only thing i can see is the SQL Server Agent and SQL Server Browser has stopped / is not running and the TCP/IP Protocols for SQLEXPRESS is set to disabled - I am unable to enable it without a further Access is denied (0x80070005) error.
I have tried to follow all of the guides but cannot progress. Could somebody please offer some further guidance?
I have resolved the issue. It was an extremely silly oversight! On installation, the server name in the Visual Studio 17 Connection Manager was listed as: Local MachineName only. In SQL Server, the Server Name was listed as: LocalMachineName\SQLEXPRESS. The Server Name in VS17 has to be exactly the same as SQL Server. As i said, this is a very silly oversight on my part but have documented for future reference.

I have a VPS, installed SQL Server and everything but the problem is that I can't access the database from outside my VPS.
I tried the following:
Enable port 1433 in firewall
Enable windows and server authentication in SQL Server
Enable TCP/IP
Make sure that SQL Browser is Running
When I connect using SQL Server authentication inside my VPS, it works fine, but from my PC I get this 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)
Now what should I do?
Most probably, your MS SQL server is not configured for Remote Access. Try following:
1) Open SQL Server Configuration Manager.
2) Click on Protocols for SQLEXPRESS from left hand side pane, from right hand side pane, double click on TCP/IP.This will open TCP/IP properties.
3) Under TCP/IP properties page, enter public IP address of SQL server under IP address field. Enter port number 1433 under port TCP port field.
4) Click on Apply and OK.
5) Restart the MS SQL Service.
6) Connect to MS SQL Server through SQL Server Management Studio as follows:
My response might be old though. Say you are still experiencing the same issue,
Ensure that Protocol is set to Yes
Then restart SQL Server and you
should be fine.
I'm trying to connect to my local machine name as "Server Name", and giving windows authentication, but its throwing some 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)
(.Net SqlClient Data Provider)"
Please note previously it was connecting all well some few months back, but now it throws error. I tried lot of alternatives provided around the web, but nothing worked.
Did I miss something ?
If the service is running on your local machine, try connecting with "LocalHost" as the server name.
Also, did you check that the service is running?
There are several reasons for this to happen:
Check if your SQL is up and running
Check there is no firewall messing around
Check on the configuration manager if sql services is up
Check if TCP/IP is active on the configuration manager
Sometimes, I know is weird, but his error shows up if you haven't configured your server for mixed security (both windows and SQL Server). Try connecting with a windows user with SA permissions and activate SQL authentication as well.
To do this, open SQL Server manager and connect with the SA user, right click on the server properties, check the "Security" tab for "SQL Sever and windows authentication mode"
Check this blog post that will lead you from some of the points I told you.

Check out surface area configuration. It gives options to do so.
Edit: Enable the Named pipes conenction as well. I guess you are using Named pipe to connect. Also check if the SQL server browser service is running on the DB server.
Check the Authentication mode settings. It may be set to Windows Authentication only, it needs to be in Mixed Mode to accept SQL usernames & passwords.
Also check the Server network configuration and make sure named pipes or tcp/ip are enabled add that the client is using the appropriate protocol.
If everythings are correct, you may want to connect with a upper version, for example you are in SQL Server 2005 and want to connect to SQL Server 2008.
Note that you cannot connect to a upper version.(only same version or older version are granted)
