Named Pipes Provider: Could not open a connection to SQL Server [53] - sql-server

I am trying to connect mssql server 2008 using jdbc connection.
My connection url is like
jdbc:jtds:sqlserver://localhost:1433/dbname;user=username;password=password
However I get the above mentioned exception when I try to execute a stored procedure through prepared statement
I have enabled TCP/IP and Named pipes.
I have disabled firewall.
What could be the issue.
I found out it was because the following error occurs
"ole/db provider returned message login timeout expired"...
but not sure why this happens

The linked server was configured with wrong authentication values. Hence when I tried to connect to the linked server it threw authentication exception which in turn throws above mentioned exception.
Creating a linked server with proper authentication values fixed the issue.

I had the same problem, maybe the problem is related with DNS.
I fixed the problem creating the linked server with the IP Address instead of the server's name.

AWS RDS Instance is not connecting to Jmeter

I am trying to connect my RDS instance to a Jmeter load test however no matter what I try, I keep getting this error message in the Results Tree:
Cannot create PoolableConnectionFactory (The connection to the host database-1.cqdkrfikhe1t.us-east-1.rds.amazonaws.com, named instance database-1 failed. Error: "java.net.SocketTimeoutException: Receive timed out". Verify the server and instance names and check that no firewall is blocking UDP traffic to port 1434. For SQL Server 2005 or later, verify that the SQL Server Browser Service is running on the host.)
I feel it may be a problem with my Database URL in JDBC Connection Configuration.
The picture below shows the summary report.
I have mainly tried rewriting the Database URL multiple different ways but none of them seem to work. I have also tried removing and reinstalling the JDBC Drivers but that doesn't seem to work either. I have absolutely no idea what the problem could be. Could someone please help me out with this problem?
Edit: When I change the Database URL I sometimes get this error
message as well:
Cannot create PoolableConnectionFactory (The driver could not establish a secure connection to SQL Server by using Secure Sockets
Layer (SSL) encryption. Error: "PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to
find valid certification path to requested target".
ClientConnectionId:9b700d73-f3f0-4cf6-b3a4-607fa9827219)
I think you need to use port 1433
Check out Connecting to a DB instance running the Microsoft SQL Server database engine article
So cross check the port number, VPC options, public accessibility, etc. with the values from the JDBC Connection Configuration

Not able to connect Azure SQL Database using SSMS

i am trying to connect with Azure SQL database using SSMS but i am getting the bellow error 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 Provider, error: 40 - Could not open a connection to SQL Server)
(Microsoft SQL Server, Error: 53)
We had enabled all the necessary ports also restart the SQL server, added client 'ip' in Azure firewall settings. previously we are able to connect but we changed the location of our Azure SQL server after that we are not able to connect but i can connect to another server which is located at the different location.
I found this article: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server (Microsoft SQL Server, Error: XXX) may give you some useful messages.
Basically, this error message just tell you that the client cannot make a connection to the server. It's equvalent to "SQL Server does not exist or access denied" in MDAC. Although the error message say about Named Pipe Provider, the issue does not have to be NP related. The reason is that, by default, the client stack try TCP and NP in order. If the connection attempt could not success with any of them, then NP is the last protocol tried and this is the error message to present to users.
When users see this error message, sometimes xxx is omitted. But actually, xxx is the most important part of this error message. xxx is Windows error code and it gives customer hints about why the connection fails. Here are some error code users often see. I also explain the root cause and possible solutions here.
1) xxx=53
winerr 53 means "The network path was not found". If you got this message, it means the client stack cannot find the target machine.
Here are possible reasons for this failure:
a. typo in the server name, or using "/" rather than "" between server name and instance name, e.g. "myserver/myinst" is not correct.
b. name resolution to the server name is not correct, "ping -a yourserver" would tell if that's the case.
c. The server machine is firewall'ed and file sharing is not in the exception list. You need put "File and Printer Sharing" in exception.
Hope this can helps you.

Microstrategy 10.4 SQL ODBC Connection error

I've tried to connect an SQL database from a server with Microstrategy located in another server through an ODBC connector for SQL.
First I've checked that there is a connection between the two servers executing a ping sentence with the IP Address the other server and it went through.
After making sure the connection is stablished without issues, I've tried to connect through Microstrategy without success. The error I get is the following message:
"Connection test error: Connect failed. Error type Odbc error. Odbc operation attempted: SQLDriverConnect (08001:0: on SQLHANDLE)"
Using SQL Server 2017 for the databases and Microstrategy 10.4.
Please, anybody has any clue about what might be happening?
Thanks,
look at the type of connector to the db you have. It gave me the same error until I used: "with Native Client Driver".
Could you please share the complete error message, SQL Handle error are associated with multiple error scenarios like invalid username * password, connecting 64 bit server with 32 bit ODBC driver etc. Complete error message would help me to debug it.
In general follow the steps to debug the error, (any order)
Check the version of ODBC Connection (64bit / 32 bit), it should be the same as server version.
Try testing the ODBC connection that you have created using ODBC Administrator tools to see whether there is an problem with username & password/server name or database connection issue.
Check the Database Instance/Database Connection/User Login created under the Administration option to ensure everything is working and give the correct value.
if nothing works try using the native driver given by MicroStrategy, you can access this using Connectivity Wizard.
Hope it helps..

Cannot connect to SQL Server named instance

I cannot connect to a named instance of SQL Server. I am trying to connect to domain\named_instance but this happens to all servers I try to connect to apart from localhost
The error that I cam getting looks like this:
So far I have tried:
Enabling remote connections in SQL Server
Enabling TCP/IP in the SQL Server Configuration Manager
Changing all the TCP ports in SQL Server Configuration Manager to 1433
I also tried running the command below where the number is the Process ID of the SQL Server Service:
netstat -ano | find /i “7608”
My result was as follows:
As suggested by this website.
However I do not get the ESTABLISHED return only the 2 LISTENING ones.
My IP2 IP address is set to: 192.168.2.176not 100% sure if this is right or not.
I cannot (due to security issues with my hosting company) get the IP of the server. Any and all suggestions are welcome!
I am in dire straits, and really need help!
I am using SQL Server 2008
Since you are stating you are trying to use named pipes (can be seen in the screenshots) I think you errornously trying to use TCP configuration to do this.
You need to need to enabled SQL to listen named pipes. How to do - see here.
There are multiple types of error "Cannot connect to 'Server Name'".
These error are differentiated on the basis of Error Additional Information.
One of the Solution for above error is
Connect the server using Windows Authentication.
Right Click on the Server(i.e. first option) in Object Explorer. Then go to Properties.
Go to Security then select Server Authentication as "SQL Server and Windows Authentication Mode"
Again Right Click on the Server(i.e. first option) in Object Explorer. Then select restart.
Then try again login using SQL Authentication

IIS 7 can't connect to SQLServer 2008

Sorry if this is the most seen question on the web, but this is my turn. I am trying to publish my asp.net mvc app on IIS 7 under MS Sql Server 2008. I am on a Windows Server 2008 virtual machine. I get the following classical 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)
Under SQLServer, Allow remote connections is checked. My connection string is:
Data Source=.\MSSQLSERVER;Initial Catalog=mydbname;User Id=sa;Password=mypassword
I also tried with no username/password and "Integrated Security=true". There is only one instance of SQLServer installed.
I tried to access my web page locally and remotely. There is no active firewall on the virtual machine.
Make sure you have TCP/IP set up as a transport in your SQL Server configuration tool.
Thanks guys for the try. I found the solution and it is related to an info that I forgot to give. I hope it can help someone as new as me on these things.
I use NHibernate, and the connection string is actually in the nhibernate.cfg.xml file. The one in the web.config file is actually used by my various providers (users/roles). I fixed that by removing the connection string from the NH config file. I now retrieve it with:
string connectionString = ConfigurationManager.
ConnectionStrings["myConnectString"].ConnectionString;
and I set it in NH with:
Configuration cfg = new Configuration();
cfg.Configure(cfgFile);
cfg.SetProperty(NHibernate.Cfg.Environment.ConnectionString, connectionString);
Now I get:
Cannot open database "mydb"
requested by the login. The login
failed. Login failed for user 'NT
AUTHORITY\NETWORK SERVICE'.
But this is another story, for another question if I can't find the answer.
PS: I had to use "." as the server name otherwise .\MSSQLSERVER was producing a new error "invalid connection string". Thx Ian and Jared for the tip.
is that the actual data source line from the web config?
If so then it's should be in quotes of course, for safety add a ; on the end and check that is the actual name of your instance, you can check windows services for your instance name.
try substituting localhost instead of . and can you connect from sql server management studio using the credentials in your connection string?
As mentioned by Robert, try:
ConnectionString="Data Source=(LOCAL)\MSSQLSERVER;Initial Catalog=mydbname;User ID=sa;Password=mypassword"
I'm not sure if connection strings are case sensitve, but I notice that you have 'Id' instead of 'ID'.
Edit:
Am not sure if you need \MSSQLSERVER?
are you sure it's a named instance of SQL?
try
Data Source=.;Initial Catalog=mydbname;User Id=sa;Password=mypassword
UPDATE:
from this site
did you try the following:
Make sure the server machine is reachable, e.g, DNS can be resolve correctly, you are able to ping the server (not always true).
Make sure SQL Browser service is running on the server.
If firewall is enabled on the server, you need to put sqlbrowser.exe and/or UDP port 1434 into exception.
Well I am facing the same above issue since morning (past 8 hours) did lots of stuff like create a Domain Name, setup a new application pool identity but nothing worked :(
I just made a small changes in web.config file for connection string that is:
Integrated Security=False instead of True... and now it is working perfectly
