Cant Connect To SQL Server With PHP, Error: Not Associated With A Trusted SQL Con

Sep 24, 2005

Hello
I've spent close to 3 hours trying to figure this out.
I have SQL Server 2000 Developers Version + Service Pack 4 installed on Machine A which is running Windows XP Pro. I have Machine B running XP Pro and Apache 2.0 + PHP 4.40.

SQL Server is configured to SQL Authentication + Windows Authentication.

PHP is configured as follows:
; Use NT authentication when connecting to the server
mssql.secure_connection = Off

When trying to connect with either mssql_connect or odbc_connect I get the following error:
Quote: odbc_connect(): SQL error: [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'user'. Reason: Not associated with a trusted SQL Server connection., SQL state 28000 in SQLConnect

I have tried adding a System DSN to MDAC and it can connect no problems to MS SQL. I don't know what to do, I've googled and tried every possible solution and it didn't help.

Is there a way to make SQL accept any connections? I don't care if its insecure I just need it for several days to develope a small application.

Here is the sample code I'm using to test the connection:

PHP Code:





 $myServer = '192.168.0.106'; 
$myUser = "user"; 
$myPass = "pass"; 
$myDB = "Northwind"; 

$s = mssql_connect($myServer, $myUser, $myPass) 
or die("Couldn't connect to SQL Server on $myServer"); 


$d = mssql_select_db($myDB, $s) 
or die("Couldn't open database $myDB"); 

$query = "SELECT TitleOfCourtesy+' '+FirstName+' '+LastName AS Employee "; 
$query .= "FROM Employees "; 
$query .= "WHERE Country='USA' AND Left(HomePhone, 5) = '(206)'"; 

$result = mssql_query($query); 
$numRows = mssql_num_rows($result); 

echo "<h1>" . $numRows . " Row" . ($numRows == 1 ? "" : "s") . " Returned </h1>"; 

while($row = mssql_fetch_array($result)) 

echo "<li>" . $row["Employee"] . "</li>"; 








Thanks in advance!!

Not Associated With A Trusted SQL Server Connection Error

Aug 24, 2005

Hello all.  I'm still learning SQL Server so hopefully you'll be patient with me.  I've been using mostly MS Access db files in all my web sites ...but SQL Server on a few of them.I've installed SQL Server 2000 Personal Edition for web development (testing).  I installed it under my log in name to this particular machine and used the same password and installed using Windows Authentication.  I opened Ent Mgr and created a first database. I imported my Access data and all is well so far.I "convert" a test page to connect to my local SQL Server using the uid and pwd and get the error in the subject.  I double check and the uid & pwd is in fact correct in the Security >> Logins section and it matches my code.  I switch my connection string to use "sa" with and without a password....same results.  I add ASPNET as a user and give it access to the new db and same results again.  I also tried to enclose my Accout/Machine ID in single quotes in my connection string and no luck.  Any ideas as to what I might be missing? Again - I also tried "sa" - no luck.server=MyMachineName; uid=Shane Fowlkes; pwd=123456; database=NewDatabase
Login failed for user 'Shane Fowlkes'. Reason: Not associated with a trusted SQL Server connection.

Error At: The User Is Not Associated With A Trusted SQL Server Connection

Feb 19, 2007

Hi I've got a common error using SQL server 2005

"The user is not associated with a trusted SQL Server connection"

I'm building a application using C# when using a standalone environment, it worked well. But, now I have the following environment.

A.
SQL server
Domain XXX

B. Remote machine
Application
Domain YYY

I changed SQL server to support SQL and WIN authentication mode and I have changed SQl server surface area configuration to support TCP/IP and Named Pipes for remote connections. But I still have two problems:

1. When using the IP - serverName of the dataserver, the error is

System.Data.SqlClient.SqlException: Login failed for user ''. The user is not associated with a trusted SQL Server connection..


1. When using the server name(MYServerName), I have this error:
System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

Besides, I have tried from my remote machine to use a sqlcmd -E -S tcp:myhost command but I have the same answer.

Any help, I will thank.

Error 18452 (not Associated With A Trusted Sql Server Connection)

May 3, 2006

Using sql2005 on a Novell network...

When attempting to log into Mgt Studio using windows authentication I am getting the error: Error 18452 (not associated with a trusted sql server connection) .

I added my domainuserName in sql with no problems and added the account to the sysadmin server role. However, I noticed my credentials on my pc are not listed as domainuserName but rather ComputerNameUserName. I think this is what is causing the problem but I am not sure. Can anyone lend a hand?

I'd appreciate any help,

Thanks.

The User Is Not Associated With A Trusted SQL Server Connection Error

Jun 24, 2007

Hi, I have installed MS SQLExpress 2005 on our test sever (W2K3), not a domain controller, created a database and added some tables. I am using this connection string in a asp script but get the following error when trying to connect to the database.

strAsgSQLConn = "Provider=SQLNCLI; Server=BENDERSQLExpress; Database=myasg; Uid=Admin Pwd=password"

Microsoft SQL Native Client error '80004005'

Login failed for user 'Admin€™. The user is not associated with a trusted SQL Server connection

The account I am using is the server admin account. I have installed QL Server Management Studio Express on both the server and a client PC and can connect to the database from both fine. I have tried setting the security on SQLExpress to both Windows Authentication and SQL Authentication but neither works.

Cheers

User Not Trusted/SQL Server Connection. Error: 18452

Mar 9, 2006

Hello,



I have a problem that I hope anyone here can help me with. We have a new server with Windows Server 2003 installed as well as MS SQL Server 2005. Both of these are freshly installed with default options set. The server is configured to accept both windows certification and SQL server certification (mixed), and our company has a domain setup. This server will be used for internal development, so all of the necessary people have an administrator account on the domain, which is uploaded currently into SQL Server's Security > Users folder. When I am on the server itself, I can log in using my domain name with no problem, as well as sa. However, when I try to connect to the server remotely (by my machine down the hall) using Windows Authentication I cannot. The server has BUILTINAdministrators set up for users, as well as 'sa' and whatever other defaults were there.



I CAN connect using sa remotely on my machine, though, after I enabled the account. The error message I get when I try to log in through Windows Authentication is:



*********************************************

TITLE: Connect to Server

------------------------------



Cannot connect to LAF-SQL1.



------------------------------

ADDITIONAL INFORMATION:



Login failed for user '(null)'. The user is not associated with a trusted SQL Server connection. (Microsoft SQL Server, Error: 18452)

*********************************************









No other options other than what I've mentioned are installed. The (null) is not present, but the error message shows up as two single quotes ''. I strongly suspect there is a security option set by default somewhere in WinServer or SQLServer that does not permit remote connections, but I do not know where.

Help would be greatly appreciated here.

Error 15274: Access To The Remote Server Is Denied Because The Current Security Context Is Not Trusted.

Sep 12, 2007

Hi,

I have a stored procedure servicing a queue (sql 2005).
The stored procedure updates some data in a different server and database.
If the queue contains messages and I execute manually the stored procedure, I don't have any problem at all.
However, if I set the queue to use the same stored procedure, it gives me the following error:

Error 15274: Access to the remote server is denied because the current security context is not trusted.

Any ideas?

Thanks,

Aron

Just Started Getting This Error When Trying To Connect To SQL From ASP.NET--error: 26 - Error Locating Server/Instance Specified

Apr 3, 2007

This has worked fine for weeks, and months.

I'm running Vista Ultimate. SQL 2005 is set as my Default instance, and SQL2000 is set as (local)SQL2000.

Today, actually half way through today, I restarted my computer after installing Photoshop Updates.

Upon getting my computer back up and running, I cannot access SQL2000 from any website on my computer, nor can I access it from SQL2005 Management Stdio. I CAN access it from Enterprise Manager (SQL2000 tool).

Whenever I run an web app that connects to it I get this error:


An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

Now I usually get these when ASP.NET can't point to the right spot, but in this case I'm pointing exactly where I need to go. Any thoughts?

--Edit

I should also add my password got changed a few days ago on our Domain. This was the first time restarting after the PW change.

Login Failed For User '' ..... Sql Server, Error: 18452 (The User Is Not Associated With A Trusted SQL Server Connection)

Nov 7, 2007

Hi

Last week I was receiving an error when trying to connect to two of our seven sql servers from my laptop via my domain admin account. The only fix was to have my laptop rebuilt and everything re-installed.

Today however another administrator is starting to have the same problem but to only one of the seven servers!
When that administrator uses my laptop with her domain admin account it works!?

What could possibly be going wrong with our laptops? We have not installed or changed anything.

The full error message we see:

Login failed for user ''. The user is not associated with a trusted SQL Server connection. (Microsoft Sql Server, Error: 18452)

The error being logged on the server: (two errors are logged each time)


SSPI handshake failed with error code 0x8009030c while establishing a connection with integrated security; the connection has been closed. [CLIENT: 53.35.165.148]


Login failed for user ''. The user is not associated with a trusted SQL Server connection. [CLIENT: 53.35.165.148]

Can anyone give a quick description of the meaning of this message andwhat needs to be done to get a connection.I'm running DBArtisan with SQLServer 2000 client SP4 installed.I also get the same message with MS Enterprise Manager so this iscoming out of the actual ODBC connection attempt.Thanks in advance!

Unable To Connect To SQL Server 2005 (error: 26 - Error Locating Server/Instance Specified)

Jun 5, 2007

I've installed SQL2005 on a server already running SQL2K on my laptop. SQL2K is the default instance, so I'm trying to connect to SQL2005 using MYSERVERSQL2005 as the instance.

The steps that I've taken are to apply SP2 and enable remote connections (TCP & Named pipes). I've also made sure the SQL Server Browser service is running and enabled.

The error message that I get via SQL2005 client tools is "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)"

I dont understand as to why i am unable to connect to 2005.

Any ideas?

[298] SQLServer Error: 18452, Login Failed For User ''. The User Is Not Associated With A Trusted SQL Server Connection.

I received the above error yesterday and haven't been able to trace it to any job or process running. We haven't implemented any changes to the server in the past few months, and it doesn't look to be a user-established connection, since the Client IP Address of the SSPI handshake error is from the server itself.

I logged this set of messages in SQL AgentServer error log:

Error - User Not Associated With A Trusted Connection

Jan 12, 2012

I'm trying to connect to a SQL Server database from a web app programmed in C#/ASP.NET. It's throwing an exception that says "Login failed for user 'CISUser'. The user is not associated with a trusted SQL Server connection."

I've searched around for solutions to this problem and the only one I've come across is to change the authentication mode in the SQL Server Management Studio from "Windows Authentication" to "SQL Server and Windows Authentication". But on my machine, it's already set to "SQL Server and Windows Authentication". I've restarted the server and still I'm getting the same issue.

Error When Trying To Connect To SQL-server

System.Data.SqlClient.SqlConnection sqlConnection1 = new System.Data.SqlClient.SqlConnection("ConnectionString");

Again, I really appreciate any help..

Error On Connect To Remote Sql Server

Hi all,
I am using SQL 2005 Express to store my databae on a remote server, I already set remote connections to Local and remote connections (Use TCP/IP only) and also allow it to listen all the ports. Also I disabled my firewall. Then In my web.config file I add the conncting string like below

<add name="ConnString" connectionString=" Server=123.xxx.xxx.xxxDEV11SQLEXPRESS; Database=xxx; User ID=tester; Password=test; Trusted_Connection=False" providerName="System.Data.SqlClient"/>
Then I got the following error

An error has occurred while establishing a connection to the server.  When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
Any ideas? Thanks in advance.

Unable To Connect In Sql Server 6.5 Error

Jan 23, 2004

I have loaded NT4 onto a machine with 256MB's of ram. I have put on SP6 and the hard drive is 80GB's in size. I then loaded in SQL Server 6.5 and set up my default database at 250MB's in size. I can ping all other computers on the network and they can ping me but when I try to register the database it give me a unable to connect error. This is the 10004 error. The error is Execomm and it says the DBPROCESS is dead. I guess thats cause it won't connect. The Sqlserver is running and so is the sqlexecutive running.

Help, Help, Help.

TIA

Error: Unable To Connect To Server 'servername'

Apr 29, 2008

Hi,

I am trying to connect to SQL Server through Query Analyzer but getting following error: (SQL Server is at remote web server where i have my website hosted.)

Unable to connect to server [server IP]:

Server: Msg 6, Level 16, State 1
[Microsoft][ODBC SQL Server Driver][dbnetlib] Specified SQL server not found.

I have searched this forum for this error and performed following workaround as suggested in some threads-

1. checked and set "TcpPort" registry setting.
2. TCP/IP is enabled in Network Utility.
3. "start SQL server if it is stoped" checkbox is unchecked while connecting.

But, I am still getting the above error. Should i re-installed SQL Server 2000? Any help?

Thanks,

Can No Longer Connect To SQL Server Express Error:40

Jan 14, 2007

Hi,

I have been working for a few weeks on a local SQL server (express) on my computer all worked ok, until 2 days ago I got the following error message:

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Shared Memory Provider, error: 40 - Could not open a connection to SQL Server) (.Net SqlClient Data Provider)

Where can I find the setting for remote connections? Also any idea why this happened?

Frank
