I was working with an instance of SQL Server 2012, but after updating my Avast (anti-virus) I can't connect to that instance anymore and I have this error message:
TITLE: Registered Servers
Failed to connect to server . (Microsoft.SqlServer.ConnectionInfo)
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

I just want to be precise that I have allowed all TCP/IP connection rules from my firewall system and each time I try to start the server from the SQL Server Management Studio it doesn't work :(
What should I do ?
Check is SQL Server(MSSQLSERVER) service is running or not.
RightClick on MYComputer->Manage->Service and
Application->Services->SQL Server(MSSQLSERVER)
Right Click on it and start it, then try to connect Sql Server.
services.msc just use this commend in cmd, then find out (sql server) then start it simply , will work
I also experience the same issue and this was i did to resolve the issue
. i went to my computer
. lunch sql server manager
. right-click on (MSSQLSERVER)
. and click on propertiesand check buit-in-account radio button
. select network service from the drop down and press apply and ok
That was all. Hope this work

The network path was not found
As the error states "network-related or instance-specific error" its related not being able to find the instance.
This maybe due wrong instance name, Check the spellings of the server that you are connecting to.
You may have installed a named instance like sqlexpress in that case the server name should be {YourServer}\Sqlexpress.
You can get your instance name by going to services, if its MSSQLSERVER you can connect with the machine name else you should provide the correct instance name.
Please refer the screenshot below.
If you are connecting to another machine check the network configuration of the instance by going to sql server configuration manager. If the status is disabled you can connect from outside.
If that also fails better check the firewall settings
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.

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.
This error was returned when I tried to connect with server.
Error description is:
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)
First you need to check whether SQL SERVER service is running in your system or not .For checking follows below steps in Windows.
Step 1 : Type "window" button + R ,This will open Run prompt.
Step 2: Type "services.msc" in Run prompt and hit the enter.
Step 3: Find SQL SERVER service from there.
Step 4.Start this service.
Following these steps, I have resolved this problem in my machine.
Thanks
Check your SQL Server Service is Running or not
if the server is in remote location check port 1433 is not blocked by the firewall.
if this is not the default instance, Check SQL Server Browser is running or not
Check the network connection on client PC, and verify the connection to the server using PING or TELNET
Check whether TCP/IP and Named Pipes are enabled or not.

I get the following error when I am trying to connect to SQL Azure account from My SQLServer Management studio. I use "SQL Server 2008 R2" on Windows 7 32-bit machine.

I have followed the instructions from blog.sqlauthority.com but it did not help.
This is how am trying to connect to my Azure:
And I have noticed one more error in SQL Server Services, But all the services are running.
The remote procedure call failed. [0x800706be]
PS: I have also added my IP address in the "Manage IP Addresses" in windows azure.
Any ideas!
This is a very generalized question. There can have many reasons due to which you are getting this network related error.
Have you ever got it work before? Are you sure server name is correct? Can you cross check?
Or else you can check the internet connectivity and working of VPN(if you use it)
