Jmeter can't connect to local ms sql server - sql

I need to connect Jmeter to my local MS SQL Server database. Everything works fine, when I'm working with remote databases, but when it comes to local databeses I get stuck at the beginning.
I've tried these settings to connect to my DB:
Database URL: jdbc:sqlserver://DESKTOP-IEK3G1S\SQLEXPRESS;DatabaseName=TestBase
JDBC Driver class : com.mircrosoft.sqlserver.jdbc.SQLServerDriver
And this is what i get:
Response message: java.sql.SQLException:
Cannot create PoolableConnectionFactory (The connection to the host DESKTOP-IEK3G1S, named instance sqlexpress has failed.
Error: "java.net.SocketTimeoutException:
Receive timed out". Verify the server and instance names, check that no firewall is blocking UDP traffic to port 1434, and for SQL Server 2005 or later verify that the SQL Server Browser Service is running on the host.)```

Well, I had to recreate my SQL Browser connection and manually shutdown everything that was turned on in my Firewall options and everything has started working.

Enable TCP/IP in the SQL server configuration:
Enable IP address and set the desired TCP port for the connection:
SQL Server default TCP port is 1433, most probably you should be using 1433 in your JDBC Connection Configuration setup
Enable SQL Server Authentication mode or add Integrated Security = true to your JDBC URL if you plan to connect with your current credentials (you will need to have sqljdbc_auth.dll file under Java Library Path)
Make sure to use matching SQL Server JDBC Driver
Change "Validation Query" to be select 1

TCP/IP Connection error when connecting to SQL Server database

When I try and connect to the SQL Server database, I get this error :
The TCP/IP connection to the host P5CPAJJDAD01.CORP.AD.CTC, port 1433 has failed.
Error: Connection refused: connect. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall
I can access the database using Python and also MS Access database. I'm trying to use KNIME (an analytics tool) to connect with the database but it throws that error. Which is odd considering that I can access the exact same database using Python and MS Access.
Could this be a security issue?

Cannot connect to SQL Server outside of network

I am running SQL Server and no matter what I do, I cannot access the server remotely using SQL Server Management Studio.
I keep getting this error:
A network related or instance specific error while establishing the connection to the server
I am able to access the server locally but not remotely using the correct connection details hostname etc.
I have configured/ensured the following:
SSMS server properties -> Security -> Authentication mode: SQL Server and Windows authentication mode
SSMS server properties -> Connections -> Allow remote connections
SQL Server & SQL Server Browser services are running
I have to tried to ping the server, I am getting 'Request timed out' but I am able access to the web server using browser?
Firewall TCP port 1433 is opened
In SQL Server configuration manager enabled and configured TCP/IP
What else can I check?
Thanks
Please try to do telnet in CMD
telnet serverip 1433
If you can't connect, ask your network admin to open port 1433 for source-destination and destination-source.

SQL Server Express - Connect from remote machine

I have two Win 7 64 bit machines.
On the first one I have installed SQL Server 2008 R2 Express and have no trouble connecting via Management Studio with Windows Auth and also via SQL Auth with a user I set up on the database.
On the second machine I am trying to connect to the database on machine 1 using Management Studio. I'm trying SQL Auth. I therefore obviously also can't connect to it via connection string in my .NET Code
I can ping the first machine from the second.
Things I have tried include the following:
On the machine the database is installed make sure the firewall is allowing connection on Port 1433
Made sure SQL Server service is running
Made sure SQL Server Browser service is running
Created an exception for sqlbrowser.exe in the firewall
Enabled TCP/IP Protocol through SQL Configuration manager
Allowed Remote connections in SQL Server Management Studio
The error I get 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
This is the connection string I use in code
Data Source=xxx.xxx.xxx.xxx\sqlexpress;Initial Catalog=dbName;User Id=myUser;Password=myPassword;
This can be caused by a number of reasons but I'm glad my suggestion about checking firewall ports (rather than just allowing a one-way exception for SQL Browser) led you to the answer: the firewall wasn't allowing the correct port # through.
If i remember correctly SQL Server disables remote connections by default.
Please check whether remote connections are enabled and enable them if not:
RMB on Server in Management Studio Object Explorer -> Properties -> Connections -> Allow remote connections...

Unable to make remote connections to SQL Server 2008 Express

I have a SQL Server instance installed on my VPS I've followed all the usual steps to connect remotely including:
Allowing Remote Connections
Enabling TCP/IP + adding port 1433 to the IPAll range
Creating a Firewall rule to enable the connection
Still no luck though I always get the error message:
A network-related or instance-specific error occurred while establishing a connection to SQL Server
Is there something I missed?
you must check that also all the following
check the protocol named pipes is enabled
the IP port for named pipes is enabled (usually port# 445)
the SQL Server Browser service is started
Turns outt he problem was that I hadn't allowed the SQL Server Browser through the Windows Firewall on Windows Server 2008.
So to fix:
Add an exception for the SQL Server Browser. (udp port 1434)

Cannot connect to the sql server

i am having management stdio 2005 in my machine and im tring to connect to sql server 2008
i'm receiving the following message as the inner exception .
{"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)"}
can anyone please help
thanks,
vijay.
The protocol you're using (Named Pipes) is only valid if you're connecting to the local machine. If you're connecting to a remote machine, you need to enable the TCP protocol.
Other things to check:
Is your connection string correct? Server name spelled correctly?
Is any firewall allowing TCP traffic? The default port is 1433 for a basic setup.
Open up the SQL Server Configuration Manager
Expand the node "SQL Server Network Configuration"
Click on protocols node
Right click on "Named Pipes" -> Enable
Restart the SQL Server service
Make sure the database is configured to allow remote connections.
If using an instance, ensure you're pointing at that instance in your connectionstring.
