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.

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 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.
In Visual Studio 2010 I am trying to set up a connection with a SQL Server database with the add connection wizard but the connection fails!
This is the error I get:
a network-related or instance-specific error occured 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)
Extra info;
I can ping the server!
Remote connections are allowed on the SQL Server!
SQL service is running!
What is here the problem?
To work around this problem, use one of the following methods depending on the symptom that you are experiencing:
A SQL Server login
Use a valid Windows login to connect to SQL Server. If you must continue to use a SQL Server login, you can change the security authentication mode in SQL Server to SQL Server and Windows.
A Windows account with insufficient permissions
To work around this problem, you must add the Windows account to SQL Server, and then grant the appropriate permissions to each database that the user requires access to.

I failed to connect using this connection string
strConnString = "Provider=SQLOLEDB;Initial Catalog=fsw;SERVER=HARDIXP\hardi;Integrated Security=SSPI;"
Microsoft OLE DB Provider for ODBC
Drivers (0x80004005) [Microsoft][ODBC

does not exist or access denied.
I can connect fine using SQL Server Management Studio. On the "Connect to Server" dialog, I have
Server Name: HARDIXP
Authentication: Windows Authentication
After it is connected, the server looks like this
HARDIXP (SQL Server 10.0.2531 - HARDIXP\hardi)
If I don't specify the server name, the error will be
Microsoft OLE DB Provider for SQL
Server (0x80040E4D) Login failed for
user 'HARDIXP\IUSR_GEOFFREYXP'.
Note that it is trying a different user, probably because the database was first set up for Geoffrey, not Hardi.
How can I connect to my local SQL Server from this Classic ASP code?
EDIT: I am on Windows XP, IIS 5.1
Assuming this is running on windows.
The ASP process needs to be running as a windows authenticated user that has access to the
database. Just set the application pool on the website to have this identity's credentials.
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
