I'm trying to use PHP to connect to an ODBC data source using Windows authentication. I can connect just fine to the server in SQL Server so I know it's running. When I try to run the command
$link = odbc_connect("my_odbc","","");
I get the error:
"Warning: odbc_connect(): SQL error: [Microsoft][ODBC Driver 11 for SQL Server][SQL Server]Login failed for user ''., SQL state 28000 in SQLConnect in C:\Users..."
I tried:
$link = odbc_connect("Driver={ODBC Driver 11 for SQL Server};
Server='my_odbc';Integrated Security=SSPI","","");
Which returned the message:
Warning: odbc_connect(): SQL error: [Microsoft][ODBC Driver 11 for SQL Server]Named Pipes Provider: Could not open a connection to SQL Server [53]. , SQL state 08001 in SQLConnect in C:\Users..."
Not sure what I'm doing wrong.
my_odbc is a SQL Server (2008) on a different machine. I don't have admin privileges on that database so I can't change anything on that end (such as enabling SQL Server authentication).
I am running Windows 7 and using PHP Version 5.6.12
phpinfo() indicates that ODBC Support is enabled as well as pdo_sqlsrv support
Maybe you should try PDO (the performance difference isn't that great) with SQLsrv plugin (this what I'm using to connect to my other boss' software which use SQL Server 2008 database):
$connection = new PDO("sqlsrv:Server=" . $this->sourceServer . ";Database=" . $this->sourceDB, $this->sourceUser, $this->sourcePW);
$connection->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
You can download the plugin here
https://www.microsoft.com/en-ca/download/details.aspx?id=36434
In Xampp, you must copy the dll in that folder:
C:\xampp\php\ext
And you must add that line to your php.ini
extension = php_pdo_sqlsrv_56_ts.dll
Note: Don't forget to restart your server so it can take in account the new php.ini file.
Let me know if it works for you
This error is a General Error that arises due to unable to establish connect to the server for some reasons. Its important to know what server are you using with PHP and the application used with it. Example Apache, Xampp or Wamp etc.
Here are somethings you could try like.
Let me brief, below are the reference links.
Check whether it pings
Enable TCP/IP connection SQL Server Configuration if not enabled. To do so, Open SQL Server Configuration Manager -> SQL Server Network
Configuration->Protocols for SQL server->TCP/IP(set to enabled).
Restart SQL services.
Enable Remote Connection from server
Open the Port, To do so Windows Firewall Settings-> Exceptions -> add a Port (Name:SQL;Port:1433;TCP) then from Exceptions tick SQL and save.
Enable running browser services.SQL Server Configuration Manager -> SQL Server Services - > SQL Server Browser set to running.
defining Port in connection string
add instance name with machine name if more than one instance is being used
sample
$user = 'username';
$pass = 'password';
//Use the machine name and instance if multiple instances are used
$server = 'serverName\instanceName';
//Define Port
$port='Port=1433';
$database = 'database';
$connection_string = "DRIVER={ODBC Driver 11 for SQL Server};SERVER=$server;$port;DATABASE=$database";
$conn = odbc_connect($connection_string,$user,$pass);
here are useful links that i found regarding the issue

Have a look at these links too

Someone had the same error message and asked and answered his own question here.
To quote...
I´m sorry for the troubles.
The problem was, that I was using SQL Server Native Client 11.0 as driver. I switched it to SQL Server and now it works :/
Hopefully this at least helps someone, being in a similar problem....
A significant omission from your question is how you are running PHP and with which credentials.
Assuming you are using IIS or Apache (or another web server), then your PHP process is probably running under the local system account:
Since this account is local it doesn't have any authorisation to access your remote SQL Server.
You could alter the IIS/Apache service to run with the credentials (yours?) that are authorised to connect to SQL Server, but be aware this might cause other permissions issues with the service as well as being a problem if you change your password in the future.
Try running a test script from the command line (which should run with your credentials by default) to determine where the problem is:
php -r "var_dump(odbc_connect(...));"
Look at the regedit HKLM/SOFTWARE/ODBC
what is your folder name ?
If there is a "SQL Server Native Client 11.0" then you have to write your php code like
odbc_connect("Driver={SQL Server Native Client 11.0};Server=ip;Database=db;", "user", "pass");
However some of the server like server 2008 will be record this odbc like
ODBC Driver 11 for SQL Server
Then you have to replace SQL Server Native Client 11.0 by ODBC Driver 11 for SQL Server.
You have to create an ODBC interface first. In principle, this should also work without a user and pw. If defined in interface.
$pdo = new PDO('odbc:dsnName','user','pw');
Enable in IIS on Manager PHP o PDO_ODBC:
I have authenticated by Windows with following PHP statement:
$ Conn = new PDO ("odbc: Driver = {SQL Server}; Server = JAMILI-PC \ SQLEXPRESS; null; null");
I am using Windows 2008.
I hope it solves your problem.

I've set up ODBC connections to databases before, but I'm currently having problems and can't seem to figure out what I'm missing. This isn't my area of expertise, and the Microsoft help/documentation is less than 'user friendly'. Appreciate any pointers.
I have a locally running instance of SQL Server 2014, with a couple of test databases I'm using to develop another application. Here's the info on the setup:
SELECT HOST_NAME() AS 'host_name()',
##servername AS 'ServerName\InstanceName',
SERVERPROPERTY('servername') AS 'ServerName',
SERVERPROPERTY('machinename') AS 'Windows_Name',
SERVERPROPERTY('ComputerNamePhysicalNetBIOS') AS 'NetBIOS_Name',
SERVERPROPERTY('instanceName') AS 'InstanceName',
SERVERPROPERTY('IsClustered') AS 'IsClustered'
query returns:
host_name() ServerName\InstanceName ServerName Windows_Name NetBIOS_Name InstanceName IsClustered
DECATHLETE DECATHLETE\SQLEXPRESS DECATHLETE\SQLEXPRESS DECATHLETE DECATHLETE SQLEXPRESS 0
In the Windows ODBC Data Source Administrator (64-bit) - I'm running W10 in a VMWare VM on Mac, btw - the server shows up as available when I try to configure a new System DSN. Following is the setup info:

TESTS FAILED!
I've confirmed access to the databases from SQL Server Management Studio. The login uses windows authentication with no password. I can get in, play with databases, run queries, etc. (See picture below).
I'm at a loss. I'd previously created ODBC connections with no problems. This seems to have cropped up as an issue since upgrading the virtual machine from W7 to W10. Hoping someone can point out an obvious oversight.
* Update *
Adding a screenshot of the ODBC configuration wizard below. Note that the SQL Server is showing up in the list of available servers on the wizard. So it seems to be seeing the server but failing to connect to it.
In the "Create a New Data Source to SQL Server" dialog/window, the incorrect "Server name:" is specified. Since you have a named instance of SQL Server, type in the name of the SQL Server host, a backslash, and the instance name. Here is the format: SQLHostName\SQLInstanceName.
Please check, whether you're allowing remote connections to the SQL Server using the 'Microsoft Sql Server 2014\Configuration Tools\Sql Server Configuration Tool' utility.
Go to Sql Server Network Configuration and make sure you allow TCP/IP for remote connections.
Also I'd try to play with Windows Firewall on the Sql Server PC.
I've been searching for a solution to this issue for a while now. I am trying to link SQL tables on another server to a Microsoft Access front end to make use of the Forms for data entry etc.
The comments here solved the issue and I thought I would provide a consolidated solution for clarity:
From the SQL Server Connection Manager:
Enable SQL Server Browser
From 'SQL Server Services', modify the Properties of the 'SQL Server Browser' and set the 'Start Mode' to 'Automatic'. Apply the changes and exit.
Start the 'SQL Server Browser'.
Enable TCP/IP
From 'SQL Server Network Configuration' -> 'Protocols for [your server name]', then enable TCP/IP.
Then create an ODBC connection from your local computer. From there I used the named ODBC connection in access to link the tables I needed.
I'm failing to connect to a SQL server SQLExpress. The connection worked fine a few days ago.
This is how I tried to connect (I'm using Microsoft SQL server management studio):
connection = pyodbc.connect("DSN=sqlServer; UID=myuser;PWD=mypassword")
cursor = connection.cursor()
The error I get:
('HYT00', '[HYT00] [Microsoft][ODBC SQL Server Driver]Login timeout expired (0) (SQLDriverConnect)')
In the ODBC Data Source Administrator, when I test the data source I get:
I got the similar issue.
The problem was actually I was using "SQL Server" as the driver in my ODBC settings in my DSN.
The driver should be "SQL Server Native Client 11.0".
It fixed the issue for me.
Because you are having the same issue in the ODBC Data Source Administrator I would try to focus on that first not on your code.
Here you can find a list with possible problems
Maybe this can help you find out what the problem is.
I also would try to connect with the SQL Server Management Studio.
Maybe it is possible to connect with a different user or via Windows login.
That would mean that your user might not exist anymore (maybe because you renewed tha database or something).
Also I sometimes have the problem that the SQL Server is not started either locally or on the server.
Maybe you could check if the service is started and the database is running.
I'm trying to run an application that I've developped recently. This one uses an ODBC connection to browse a defined database.
I'm trying to execute this app from a remote computer. Using VMWare, I've created a new Windows 7 environment and connected on. After that I've tried to create a new System DSN, but, when I set the logins that I'm using to connect on my local SQL Server 2008 I get
Connection failed: SQLState: '28000' SQL Server Error: 18452
[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed. The login
is from an untrusted domain and cannot be used with Windows
authentication.
How may I to deal with this, please?
Thanks a lot!
You will have to use SQL Server authentication to connect or add the local machine to the same domain where the server is.

Windows 7, IIS 7.5, SQL Server 2008 R2, ASP classic (website I want to upgrade, but need to make it works).
connection string:
Provider=SQLNCLI10; Data Source=.\SQLExpress; Initial Catalog=shoshvi_sql-db;Integrated Security=SSPI;Connect Timeout =1
I am getting this annoying error:
Microsoft SQL Server Native Client 10.0 '80004005'
Named Pipes Provider: Could not open a connection to SQL Server [53].
filename.asp, line 15
What I tried, as I remember:
Test connection using SSMS (works, to localhost and to other server in LAN)
Test connection using SQLCMD (works, to localhost and to other server in LAN)
Tried many datasources/servers ( name\SQLExpress, .\SQLExpress, .\SQLEXPRESS)
Tried to change settings in Start Menu\Programs\Microsoft SQL Server 2008\Configuration Tools, enable TCP/IP, Named Pipes, look all sub items and find wrong configuration.
after any change, I was restarted service.
Tried to enable SQL Server Browser.
Tried to connect to other SQL Server in the same network, using SA and SA password (in the other "server" I could use IIS/ASP/MSSQL and works fine).
Tried to disable Windows Firewall
Tried to enable remote connections to SQL Server Express
Tried Integrated Security=SSPI
Tried Windows Administrator password
Tried change to TCP/IP (and get other error, same reason)
Tried to search google, and stackOverflow and other for an idea.
Tried similar questions here.
What more?
Thanks !
Try this. And make sure you have TCP/IP enabled under 'SQL Native Client Configuration' on SQL Configuration Manager.
PROVIDER=SQLNCLI;DRIVER={SQL server};SERVER=127.0.0.1;DATABASE=shoshvi_sql-db;UID=username;PWD=password;
Double-check that any ALIAS you're using is created properly.
I was encountering exactly the same error and it turned out to be that I hadn't created the alias used in a script when trying to run it on a new machine.
I'm trying to make a connection to a SQL Server Express DB on localhost, but I get the following error message:
Microsoft OLE DB Provider for SQL Server (0x80004005)
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or
access denied.
The code I'm using is
Dim connection
Set connection = CreateObject("ADODB.connection")
connection.connectionString = "server=localhost;Provider=SQLOLEDB;Data Source=RiskManagement;Initial Catalog=RiskManagement;User ID=sa;Password=myPass;"
connection.Open()
Any ideas?
First thing to always check is that you have configured SQL Server to allow remote connections.

I also faced same issue, when I investigated around the network connectvity then I come to know from application server (example Windows 10.10.10.10 or AppServer) is unable to connect database server (Like DBServer or 10.10.10.11). So once check whether it's pinging from the application server, where application is hosted or located.
I got this issue because ESET firewall was on.
I installed an update of a VB6 program. The new .exe had to be entered into the firewall
