I have installed SQL Server 2008 R2 on Windows 10 (64-bit). My server name is SRIDHARAN-PC and I gave it correctly and I got an error like:
A network related or instance-specific error occured while establishing a connection to SQL server.
And when I go for services.msc and start the SQL Server service, I get an error like
Windows could not start the SQL Server service (SQLEXPRESS) service on local computer
The system cannot find the file specified.

I am trying to connect a Tableau desktop to a remote MongoDB server using ODBC connector. I have followed the steps mentioned in this page https://docs.mongodb.com/bi-connector/current/connect/tableau-auth/#std-label-connect-tableau-auth
But I am getting the below error
[MySQL][ODBC 1.4(w) Driver]Can't connect to MySQL server on '13.38.33.197' (64)
Generic ODBC requires additional configuration. The driver and DSN (data source name) must be installed and configured to match the connection.
Unable to connect using the DSN named "test new". Check that the DSN exists and is a valid connection.
Please help me in resolving the issue.
This error occurs when a running mongosqld instance cannot be found. Here are the steps to follow for a successful connection to mongoDB from Tableau desktop.
Install mongoDB connector for BI on your machine.
In command prompt, navigate to mongosqld file location.
Use the below command to provide host and connection details
mongosqld --mongo-uri --auth --mongo-username --mongo-password --mongo-authenticationSource
The above command will create a live connection on localhost.
Create a system DSN with host/server IP as localhost or 127.0.0.1 and the same DB credentials.
On Tableau Desktop, select connect via Other Databases (ODBC).
Select the system DSN created and click on connect.
I have installed Microsoft SQL Server 2019, I am able to connect using hostname and Windows authentication from SSMS, but when it try to connect to it using localhost or the IP address and port 1433 from SSMS or DBeaver, it doesn't connect.
I have verified the service status, port no, server logs, all looks good but still unable to connect. Can somebody please help?
The issue is resolved after enabling server authentication.steps :-
1. In SSMS right click on conection
2. Go to properties-> security
3. Change authentication mode to windows and SQL server from windows authentication.
After making this change , I am able to connect to the sever using ipaddress.
I am using Microsoft SQL Server 2008 R2 Express, suddenly I got a error while I am trying to connect:
TITLE: Connect to Server
Cannot connect to DEBANJAN\SQLEXPRESS.
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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)
Please help me soon.
There are many points to check to allow remote connection to SQL Server :
Open firewall TCP ports in inbound rules (135, 1433, 1434)
Check that SQL Server use the 1433 port : http://support.webecs.com/kb/a868/how-do-i-configure-sql-server-express-to-allow-remote-tcp-ip-connections-on-port-1433.aspx
Allow TCPIP protocols in SQL Server Configuration Manager (32 & 64 bits)
Enable SQL Browser in SQL Server Configuration Manager
This worked fine for me with Windows Server 2012 R2 & SQL Server 2008 R2 Express SP3.
I have just install mssql 2008 r2. I am unable to connect to the server remotely.
I have followed the details on this post in regards to openning the firewall and allowing remote connections. Actually for testing purposes i've disabled the firewall.
I'm getting error 26. Which refers to be unable to find the instance name.
I've tried difference variations of the following my local mssql 2008
Servername: remoteIp\instanceName
Login: myUser
Password: myPassword
If my servername correct
Server Info:
Windows Server 2008, SQL Server Standard 2008 (64-bit)
I recently upgraded to SQL 2008 and was interested in trying out T-SQL Debugging. Initally encountered some firewall issues, but after disabling my workstation's Windows Firewall and having TCP port 135 and UDP 4500/500 opened up by the IT group I got a little further.
Now I get the error message:
Unable to start T-SQL Debugging. Could not connect to computer 'servername'. Logon failure: unknown user name or bad password.
My workstation and server are on different domains and I use Windows authentication to connect to the machine. My account is sysadmin and connects to the server fine in SSMS. The SQL Server service is running as a different service-level account.
Thoughts?
I have seen the same error message. My configuration, however, is different. I am connected from Management Studio 2008 with an SQL user to a SQL Server 2008 instance.
I user a sniffer (Wireshark) to monitor IP traffic en saw the following:
DCERPC Bind: call_id: 5 IRemUnknown2 V0.0, NTLMSSP_NEGOTIATE
DCERPC Bind_ack: call_id: 5, NTLMSSP_CHALLENGE accept max_xmit:

Note: my actual domain and user have been replaced by and , respectively.
Maybe, this can help you to get more detailled information.
At this point, I am stuck. I tried to give this domain user access to the server, but do not have permission to do so. Also, I am not sure if this is needed, because I connect using an SQL user.
