I have a Visual Studio C++ project (unmanaged C++) in which I try to connect to a SQL Server 2008 instance on another machine in the LAN. I use TCP/IP. My connection string is:
"DRIVER={SQL Server Native Client 10.0};Server=tcp:169.254.204.232,1433;Network Library=DBMSSOCN;Initial Catalog=myDB;User ID=myDBUser;Password=myPassword;"
Important fact: I am able to successfully connect remotely to that instance with user id myDBUser and password myPassword using SSMS -- using SQL Authentication mode (and specifying TCP/IP in the connection options)! Also, once logged in I can successfully navigate the database myDB.
So yes, I have enabled Mixed mode authentication on my server.
Also note that the same code was successfully connecting when my instance was local and I was using Windows Authentication. In other words, what changed since this whole thing last worked is that I moved my server to another machine, am now using SQL Authentication, and therefore changed my connection string -- the code has otherwise not changed at all.
Here is the error message I get in my SQL Server 2008 instance's Server Logs:
Login failed for user ". Reason: An attempt to login using SQL Authentication failed. Server is configured for Windows Authentication only.
Error: 18456, Severity: 14, State: 58.
Notice that the user being quoted in that error message is blank, even though in my connection string I specify a non-blank user ID.
Other connection strings I tried that give the same result:
"DRIVER={SQL Server Native Client 10.0};Server=MACHINE2;Database=myDB;User ID=myDBUser;Password=myPassword;" (where MACHINE2 is the windows name of the machine hosting the sql server instance.)
I do not specify an instance name in the above connection string because my instance is installed as the default instance, not a named instance.
Any ideas on how to solve this?
UPDATE: I solved this problem it seems. Are you ready to find out how silly and totally unrelated that error message was?
In the connection string, I just changed "User ID" to "uid" and "Password" to "pwd", and now it works.
I now see "Connected successfully" in my SQL Server logs...
Try running SELECT SERVERPROPERTY('IsIntegratedSecurityOnly'); if it returns 1 is Windows Authentication if 0 Mixed. If it returns 1 is definitely Windows Authentication and there must be something else wrong.
I think I solved this problem by doing this...
right click on servername on object explorer -> Properties -> Security -> Changed server authentication to SQL server and Windows authentication mode -> click OK.
after that open server on object explorer -> Expand security -> Expand Login -> right click on your login -> properties -> type new password -> confirm password -> OK.
then disconnect your SQL and restart your system. then login SQL server 2008 with changed password in sql authentication mode.
Thanks :)
The answer: In the connection string, I just changed "User ID" to "uid" and "Password" to "pwd", and now it works. I now see "Connected successfully" in my SQL Server logs...

I can login in into local Microsoft SQL Server Management Studio 2018 using Windows authorization and connect to my local SQL Server, but I can't change or view password.
I tried opening securities-login-sa, open login properties window, change password and confirm it, click OK. After restarting server , password is back to old 16 characters length. I also tried creating several new users, and change password the same way, again password is back to 16 characters length for each new user after restart.
Screenshot of login properties window in SQL Server Management Studio
I also tried creating new query to change password using alter login command in various formats, and I get successfully completed message, but to no avail, after restart old password is back for each user, be it sa , or some user I created.
Screenshot of SQL command
I can't login using SQL authentication, I get a "can not connect to " message.
Screenshot of message after SQL Server authentication attempt
After this I changed server properties-authentication mode to SQL Server and Windows authentication, and changed password, again no luck, password stays the same.
I would be very grateful if someone could help me here.

I change the logon to network serivce of Sql Integeration service fron SQL server configuration but still m getting this error please help
Try this.
When you use username and password to log on to your computer, sql server need to verify the user who authorized to use the sql server service.. But sometimes sql server cannot redirect to the account, so we need to configure the user.
Here's the step :
1. open sql server configuration mangager
2. choose sql server 2005 services
3. right click sql server integration services, choose properties
4. choose log on tab, select this account, enter your username and password which is used to log on your computer.
5. reopen the business intelligence studio. There you are, the task component can work properly again.
It also might be that this is a custom component which is not installed at your global assembly cache (in case you are not running it at the server to which it was originally deployed).

Typically, to troubleshoot this, you go to SQL Server Configuration Manager (SSCM) and:
ensure Shared Memory protocol is enabled
ensure Named Pipes protocol is enabled
ensure TCP/IP is enabled, and is ahead of the Named Pipes in the settings
Maybe it can help: Could not open a connection to SQL Server
Note : If this is a new instance of SQL Server be sure SQL Server and Windows Authentication is enabled
Right Click the Server in SSMS and pull up server properties
Go to Security--> Select 'SQL Server and Windows Authentication Mode'
Restart the Server and Login with the credentials
Check if your connection string has "Trusted_Connection=true" added.
I had this same error message, turns out it was because I didn't have mixed mode auth enabled. I was on Windows Auth only. This is common in default MSSQL deployments for vSphere, and becomes an issue when upgrading to vSphere 5.1.
To change to mixed mode auth you can follow the instructions at http://support.webecs.com/kb/a374/how-do-i-configure-sql-server-express-to-enable-mixed-mode-authentication.aspx.
I had the same error by in SQL Server Management Studio.
I found that to look at the more specific error, look at the log file created by the SQL Server. When I opened the log file, I found this error
Could not connect because the maximum number of ’2′ user connections
has already been reached. The system administrator can use
sp_configure to increase the maximum value. The connection has been
closed
I spend quite some time figuring this out. Finally running the following code fixed my problem.
sp_configure 'show advanced options', 1;
go
reconfigure
go
sp_configure 'user connections', 0
go
reconfigure
go
More on here and here
Edit
To view logs search for "logs" on windows startup button, click "view events logs". From there go to Applications under "Windows Logs". You can also choose "System" logs to see system wise errors. You can use filter on current logs by clicking "Filter Current Logs" on right side and then select "Error checkbox".
Just another possibility. I had to restart the sql server service to fix this issue for me.
The "real" error was in the SQL error log:
C:\Program Files\Microsoft SQL Server\MSSQL14.MSSQLSERVER\MSSQL\log\ERRORLOG
Path will depend on your version of SQL Server
You should enable the Server authentication mode to mixed mode as following:
In SQL Studio, select YourServer -> Property -> Security -> Select SqlServer and Window Authentication mode.
Goto to SQL server using windows Credentials - > Logins - > Select the Login - > in the Properties -> Check if the Log in is enabled/disabled.
If Disabled, make it enable, this solution worked for me.
Adding this to my connection string worked for me:
Trusted_Connection=true
In C# and SQL SERVER, we can fix the error by adding Integrated Security = true to the connection string.
Please find the full connection string:
constr = #"Data Source=<Data-Source-Server-Name>;Initial Catalog=<DB-Name>;Integrated Security=true";
By looking into SQL SERVER log file in "C:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\Log\ERRORLOG", it says
"Login failed for user 'XXXXX'. Reason: An attempt to login using SQL authentication failed. Server is configured for Windows authentication only. [CLIENT: ]"
The fixing method is to open "Microsoft SQL Server Management Studio" -> Right click the SQL server and then select "Properties" -> Security -> Change the authentication to mixed mode. -> Restart SQL server.
I was getting this error today. In my case, looking at the ERRORLOG file on the SQL server gave me this error:
Login failed for user ''. Reason: Failed to open the
database '' specified in the login properties.
This was because I had deleted the "Default database" of this user a few days ago. Setting the default database to my new database fixed the problem.
Hope this helps someone else.
I forgot to add the "Password=xxx;" in the connection string in my case.
I had the same error, Fixed it by ensuring that SQL server had SQL authentication mode enabled.
see images below.
To enable, go to server properties.
Click on the Security tab and select the SQL server and window server auth mode and press ok
You will need to restart the server for the changes to reflect, should be fine now.
Enable Mixed authentication mode while installing MSSQL server. Also provide password for sa user.
Hi Just enable both for server authentication as per screen shot attached below.
All good and valid courses of investigation especially the logs for more info.
For those hitting this it might be a simple gotcha where when you have created the DB User you may have enforced a password policy and left the user to change the password on first login (i.e. left the checkboxes around the password field at their default values).
Very easily done in SQL Management Studio and can of course cause authentication issues off the bat that are masked unless you look into the logs.
Check that the server name you're logging into with SQL Management Studio matches your connection string.
I was getting this error today.
It turned out that I hadn't realised the machine with SQL Server installed had multiples servers running. I had in fact put my database in a totally different server to the one I thought I was using. (So my connection string was pointing to a server with no database)
Hence, When .net tried to access the database it couldn't find anything and gave only a misleading error message about pipes.
I opened the correct server in SQL Management Studio, added my database to and then all worked fine.
(If the correct server isn't available in the dropdown, try browsing for it.)
In my case it was a spelling mistake in the database name in connection string.
This is old but I had the problem in the connect dialog that it was still defaulting to a database I had removed. And by running those commands the default database in the prompt wasn't changing.
I read somewhere I can't find now, that if you open the "Connect to Server" dialog and then select "Options" and select "Connection Properties" tab by typing the default database (no by selecting from the drop down) the database will then stay on that new value entered. This sounds like a flaw to me but in case someone was wondering about that, that should fix the issue, at least on SQL Server 2012
I know i am probably the only one that will have this problem in this way. but if you deleted the mdf files in the C:/{user}/ directory, you will get this error too. restore it and you are golden
I ran across this in a code-first application which expected the database to be there:
Make sure the database is created / the name in the connection string is correct.
I had the same problem. I tried all the suggested answers in this page but to no avail! Finally, I tried the steps below and it worked for me:
In SQL Server Management Studio Object Explorer, right-click the server, and then click Properties.
On the Security page, under Server authentication, select the new
server authentication mode, and then click OK.
In the SQL Server Management Studio dialog box, click OK to
acknowledge the requirement to restart SQL Server.
In Object Explorer, right-click your server, and then click Restart.
If SQL Server Agent is running, it must also be restarted.
Then try this in your Package Manager Console:
Scaffold-DbContext "Server=YourServer;Database=YourDB;Persist Security Info=False;User=YourUserName; Password=YourPassword; MultipleActiveResultSets=False;Encrypt=False; TrustServerCertificate=False; Connection Timeout=30;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models -Context DatabaseContext -f
In my case, my situation was a little different.
1. My Mistake: I was missing a ";" in stringConnection. I know this is a newbie bug, but I am new to C # and SQL Server. I have one day :)
private string connectionString = "Data Source=localhost;Initial Catalog=FundamentalsCSharp"
+ "User=sa;Password=123456";
2. My Solution: Put a ";" it was missing after the phrase "FundamentalsCSharp" and it worked.
private string connectionString = "Data Source=localhost;Initial Catalog=FundamentalsCSharp;"
+ "User=sa;Password=123456";
3. Note: Change "FundamentalsCSharp" for your owned Initial Catalog.
I hope this can be of use to someone. Thanks!
In my case, my project is Asp.net Core 3.1 and this is my connection string
"ConnectionString": "Data Source=.; Initial Catalog=WebDB; user Id=sa; Password=123"
And database name in sql server webdb (lower case in sql server).
After many time change database name webdb in connecion string and worked fine.
For those doing entityframework code first, also check to enture you have done your migrations.
The best place to look for the root cause is the sql server error log
In my case My disk was full 99%, It worked after I freed up to 80% of the disk.
I'm creating new login in SQL Server 2008 with following sql script:
CREATE LOGIN [xyz] WITH PASSWORD='xyz',
DEFAULT_DATABASE=[master], DEFAULT_LANGUAGE=[us_english],
CHECK_EXPIRATION=OFF, CHECK_POLICY=OFF
It creates new login successfully. But when I try to login with it using SQL Server Management Studio it fails saying:
A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233)
What's wrong? How do I solve this issue?
Here is how I done it, maybe it works for you too.
login Microsoft SQL Server 2012 with windows authentication.
right-click onto the server name in Object Explorer and click Properties
In the new tab click Security
select SQL Server and Windows Authentication
Ok
Close the SQL server management studio.
start+run
write services.msc
search for SQL there and restart all services.
that works for me.
It's also possible that you're trying to use SQL Server Authentication without having enabled it. To fix this, right-click Properties on your server instance in SQL Server Management Studio, and update the security settings to include "SQL Server and Windows Authentication mode".
Looks like you're trying to connect using named pipes, but SQL Server is not listening on that protocol. See MSDN.
The two fixes MSDN suggests are:
Connect using TCP/IP, or use the SQL
Server Configuration Manager to
enable remote connections using named
pipes.
Using SQL Server Configuration
Manager on the client computer, move
TCP before named pipes in the
protocol order list.
I had a similar issue:
1. log in as the master user or windows authenticated user.
2. right click on the database --> properties --> security -->
3. change Windows Authentication mode to "SQL server and windows authentication mode" by clicking on the radio button. (if it is not)
4. restart the server
I had the same issue when i first setup SQL Server 2014 on my local machine.
In my case the solution was to set a correct defualt database.
Login with Administrator in SQL Server
Go to Securities >> Logins >> select your user name and go to properties
From Status >> uncheck user account lock check box
Change password for the user
Restart the sql server and login with your username.
I was facing the same error.
I've resolved the error by following below mentioned steps:
Disable named pipes and restart sql services.
After restart sql server I enabled names pipes and did a sql server restart again (Link for Step 1 and 2)
Connect to SQL server via studio.
Right click on SQL instance --> Properties --> Connections --> "Set the Maximum number of 5. concurrent connections to '0' ".
Save the change.
Restart the SQL server if possible. (Link for step 3 to 6)
I hope this will help someone
This is might not be a connection issue . Check your default database and if that is online . More commonly this issues seen when the default database will be offline or not exists . If your default database other than master ,better check this option.
I got a way to go around the problem.
Open one instance and login using the windows authentication
allow sql and windows auth both by right cliking on the db server.
Open second instance and login using sql authentication.
bingo the sql authenticated instance open .. :)
Actually in this way we cheat the sql authenticated instance as it tries to find an already running instance.. worked fr me.. good luck
I tried most of the solution but was not able to solve it until I found this URL which says to do the following:
Open SQL Server Management Studio and run the these queries:
sp_configure 'show advanced options', 1;
go
reconfigure
go
sp_configure 'user connections', 0
go
reconfigure
go
The reason why we got this error is that the user connections was reset to 1, so only one user was able to connect with the SQL server.
just a simple query worked for. I hope this will work for others as well.
I have not used the script style, but login through GUI I encountered the same error code. I had entered wrong user name and this is why I was getting the Sql Server, Error: 233. In order to resolve this, you should input the following information:
Server Name: MachineName\SQLEXPRESS
Authentication: SqlServer Authentication
User Name: Assigned user-name or simply sa
Password: xyzpqr
NOTE: Here I have wrote above data for demo purpose only, actual data is your machine & software's properties.
According to: https://msdn.microsoft.com/en-us/library/bb326280.aspx
Go to --> Remot setting
Go to "Remote" tab
in "Remote Assistance", Tick "Allow Remote Assistance connection to this computer", Click the "Advance" button and tick the "Allow..." and in the "Invitation" set the "30 days"
Then in the "Remote Desktop" part
Just tick "Allow remote connection to this computer"
After following the examples here and still not getting in, I found that my sa login was disabled. The following got me in:
Logged back in under windows authentication.
Expanded Security Tab
Expanded Logins Tab
Right-clicked sa and selected Properties
Went to the Status Tab
Under Login: Clicked 'Enabled' radio
Restarted Server and logged in as sa.
This assumes you have set sa password already using
ALTER LOGIN sa WITH PASSWORD = '<enterStrongPasswordHere>' ;
"A connection was successfully established with the server, but then an error occurred during the login process."
I was getting this problem from sqllocaldb when used from within Docker. The problem was the Docker image was not allocated enough memory. Increasing the memory actually fixed the problem.
I have this problem which I am trying to debug for a lot of time.
The setup is like this:
i. The application is a Windows application developed using VS2005, .net 2.0.
ii. I use the Cyrstal reports component Crystal Report Viewer and dynamically display various reports in the same form.
iii. The db is SQLSERVER Express 2005 and situated on a different machine.
When I run the application on the db server, I am able to view the report. However, when I run the application on a different machine which is connected to the above dbServer, I get an error. ( I dont get this error on my dev setup)

Use datasource=servername or ip address\instance name if available,port number
Default port number is 1433 or 1434
My problem was solved with this. Posting for the use of others.
If this is a standard installation of SQL Server Express, bear in mind that the only connection method installed by default is shared memory, and is only available on the server -- you would need to enable another connection protocol such as Named pipes or TCP/IP. To turn networking on, Use SQL Server Configuration Manager to enable relevant protocols and start SQL Browser.
It's telling you exactly what's wrong.

Okay. I bet we have "localhost" as part of the instance name in my connection string. Since I'm no longer on the "localhost", this obviously won't work. Let's try there first. Then perhaps it's the credentials that I'm using to query my database. Usually what I do is create a RO user that can only do selects on my db and use that for CR. If none of these are getting me close, let's try making sure that remote connections are enabled for SQLEXPRESS

Ok it's definitely a connection issue.
