Connection Strings, Trusted-connection VS Username-password, SQL Server 2005 Express
Mar 9, 2007
All --
Please help.
I have some questions about connection strings.
BACKGROUND...
Note that I am using the "SQL Native Client OLE DB Provider", SQL Sever 2005 Express, ASP.NET, C#.NET, and VS.NET 2005.
Note that I do not want to use the "Attach a database file" type of connection string.
Note that I am using the site http://www.ConnectionStrings.com as a reference.
Note that this "Standard security" connection string...
<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Uid=MyDatabaseUser;Pwd=MyDatabasePassword;" />
...does not work and causes the following run-time error...
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.)
Note that this "Trusted connection" connection string...
<add name="LocalSqlServer" connectionString="Server=MYTESTOFFICESERVERS;Database=MyDatabase;Trusted_Connection=yes;" />
...works but is less-than ideal because it uses a Trusted Connection rather than a Username/Password combination.
QUESTIONS...
(A) What exactly does the error in Item 4 mean?
(B) Do 4 and 5 imply that one must use a Trusted_Connection for all SQL Server 2005 Express connection strings when the database does not reside in the web application's App_Data folder or use a "Attach a database file" type of connection string?
(C) Are there any alternatives?
(D) What do you suggest?
Please advise.
Thank you.

I just started evaluation of the server and meet the fist problem. I searched the forum however most answers related to use SQL Server manager and security tab. Note I use the express edition which has no manager, but only configuration manager. There is no security tab. So can somebody help in setting up trusted accounts for SQL server express edition?

Hello,
I am working on porting a Windows Forms VB.net VS 2003 app with a SQL 2000 backend - to using VS 2005 with SQL Express 2005.
I cannot seem to figure out how to set my connection string to work in the new environment. I have already recreated my database in SQL Express 2005 and ported the VS project to VS 2005.
The old string was (in my app.config file):
<add key="ConnectionString" value="workstation id=MAIN1;packet size=4096;user id=sa;data source=MAIN1;persist security info=True;initial catalog=Dbname;password=####" />
Any ideas?
Thanks,
Sam

Hi All,
We have setup a SCOM 2007 Server and in this we have SQL 2005 SP2, We are using two accounts one for OPRATIONAL DATABASE and another one for REPORTING DATABASE after this setup everything was working fine but suddenly my SDK account which is for REPROTING DATABASE was locked by entering wrong password and afterwards I unlocked the password but SINCE this i'm not able to connect to my REPORTING DATABASE and i'm getting following ERROR:- Login Failed for user 'username'. The user is not associated with a trusted SQL Server connection.
Taken following action to rectify this problem:
1) Resetting the SDK password with the same password.
2) Restarted all the SQL and SCOM services.
3) Restarted the Server as well.
4) Converted from WINDOWS AUTHENTICATION mode to MIXED mode.
But the problem is still persisting, Please help ASAP.
Regards,
Akhilesh

Hello. I have recently installed MS SQL SERVER 2005 and when I was installing it, it asked me for the username and password, and there I had 2 options: either write my own, either select "Use Windows Authentification". I selected the "Windows Authenthification" ( I guess that means that it uses my username and password from Windows ).
Now, Im trying to connect to the Server using Java and JDBC, but I have a problem: I have to specify the username and the password of the connection! My windows' only account is "Vlad" and I have no password. I tried these options, but it didn't work. I also tried with empty string "", and with "sa", "sa" but it didn't work either. I get an error saying that "Login failed for user 'Vlad'. The user is not associated with a trusted SQL Server Connection."
Any ideea of what the username/passwords are or how to get them?.
Thank you for your time.

When using jdbc with IntegratedSecurity, I run into this problem when the machine is not part of a domain & gets its IP address via dhcp. Is this expected behavior or a bug in the jdbc driver.
The SQLServer and client application are installed on the same machine and a local admin is logged in, running the client app.
If I change one of the two parameters mentioned above, the connection can be established leading me to believe this may be intentional for security issues. Am I correct?

Here is the way SQL Server 2005 Express is currently setup:
SQL server has IP of 192.168.8.200. (DMZ zone - 192.168.8.*)
Web server has IP of 192.168.8.81. (DMZ zone - 192.168.8.*)
My workstation has IP of 192.168.1.100. (Trusted zone - 192.168.1.*)
So, I've been developing a web application that was stored in the trusted zone, and this application didn't have any problem connecting to the database on *.8.200. I even have SMSE running and I can manage the database without any connection problems. I moved the web application to the web server, without changing the web.config file, and now it will not connect from the webserver.
In the web.config file, the connection string is pointed to 192.168.8.200SQLEXPRESS. I'm confused because it seems that since the SQL server and the Web server are in the same zone, there shouldn't be any connection problem.
In the Firewall, I have port 1433 open for TCP/UDP for ANY -> ANY...so I think the firewall is configured correctly?
Please advise! Thanks!

Hello everyone! I am having some more problems while trying to get my site online. I built the site offline using Visual Web Developer Express Edition, and used "SQL Server Express" that comes with ASP.Net. Therefore, I have the ASPNETDB.mdf and mydatabase.mdf in the App_Data folder. Now, on my local machine everything runs fine. When I tried to put the site online however, I get 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) This is the connection string in my web.config file: <connectionStrings> <add name="ConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|mydatabase.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/> </connectionStrings> Now, my web-host does have SQL Server 2005. Does my ASP.Net application use that though, since I have it running just through SQL EXPRESS? Also, does anyone know where I could change my "SQL Server 2005" settings? My web-host uses Plesk 8.2.0, and the database managing program is "ASP.Net Enterprise Manager", but I can't find any options anywhere to change the Server settings to allow remote connections. Any help would be greatly appreciated! Thanks in advance, Markuu

I recalled i needed something like "Server.mappath("path-name")"anyone know what i need to do?

Hi All,
We are using the Windows Task Scheduler as a substitute for the SQL Server Agent, which isn't available in the Express edition. The scheduled task just calls a batch file, which in turn, runs a stored procedure using osql with the -E option for a Trusted Connection.
SQL Server Express has been installed using the defaults, which means the service is running in the "NT AUTHORITYNETWORK SERVICE" account. The scheduled task we create is set to run using the "NT AUTHORITYSYSTEM" account.
Now we find that on Windows Vista (tested using Ultimate Edition) that the scheduled task fails to run the stored procedure until the machine is rebooted the first time after installing SQL Server Express. When I say "fail", I mean that the stored procedure isn't executed. The scheduled task however completes and reports no errors. On Windows XP, we do not run into this problem so I suspect it has something to do with the UAC in Vista?
We further found that after installing SQL Server Express and creating the scheduled task in the "NT AUTHORITYNETWORK SERVICE" account, the scheduled task (and stored procedure) runs fine WITHOUT requiring a reboot.
Can anyone explain why a reboot is needed to get SQL Server Express to run the scheduled task correctly under Windows Vista and the SYSTEM account?
Any help or thoughts greatly appreciated.

This works but I don't get the headers in the file. How can I include the headers?

Hello All,
I know this issue has been dealt with every where in the universe. but none seem to solve my problem. I need help desperatelyThe Web Application is a Classic ASP/Sql Server 2000 using two computers in the same physical network:Computer-A is the Sql Server2000 running Windows XP Professional.Inside Sql Server2000 i created a login, AA, as a dbowner of a database called XXX. Inside XXX, AA is right there as a user.
i configured the SqlServer to accept mixed (Windows and Sql) logins.I restarted the computer and i logged into sqlserver successfully as AA. Everything is fine here.
Computer-B is the Web Server running IIS in Windows XP Professional.Here, I successfully created a System ODBC i named EEEE to connect to XXX using the AA login. Everything is fine up to this point.But, to my greatest surprise when i use - conn.Open("DSN=EEEE;UID=AA;PWD=AApassword;") in a classic ASP page, it returns this very famous error.
What did i do wrong? Please help

Two days ago I had no problem creating or running DTS packages.
Now, when I try to design or run a DTS package that has a connection to SQL Server (using userid 'sa') I get the following error message:
Error Source: Microsoft OLDDB Provider for SQL Server
Error Description: Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection.
I am running from an NT Client. The only thing that might have caused a problem is that we had a power hit yesterday.
Has anyone seen this problem, and does anyone know what need to be done to resolve the problem?
Thanks, in advance.

I just upgraded my SQl tools from 7.0 to 2000. Now, when I want to access information from our sql server (v. 7.0) through ODBC, I get an error, the login box comes up with the trusted connection checked (this particular database doesn't use trusted connection). My PC runs Windows 2000 and has for over a year. Others in my company have developed this issue immediately after installing W2k on their computer or installing other software. Is there a way to have the login NOT have trusted connection checked?
Thank you.

I am trying to connect to a SQL Server database using windows athenication over Cisco VPN 4.0.3. I recieve the error "Login Failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection" using Enterprise Manager. I am able to connect sucessfully when connecting using a SQL Server logon. I able to connect to the domain and connect to remote drives. I am able to using Microsoft Outlook with no problems.
I am running Windows XP and connecting to SQL Server 2000 running on windows 2000. I have no problems connecting via Windows authenication at work. I only have the problem over VPN. I just recently rebuilt my hard drive due to hardware failure, and have not been able to connect using Windows authenication since I re-installed all of my software. Prior to that, it worked great. Does any body know what might be the problem and what the solution is?
I appreciate any help that I can get.

Hi All... I'm using asp.net 2.0 against a SQL Server 2005 database and am getting an error,
Login failed for user 'MyUser'. The user is not associated with a trusted SQL Server connection.
I've done searches for this error and most say to switch from windows-only authentication to mixed mode. That seems more like a workaround rather than a solution. I mean we should be able to use windows-only right? So how does one set up that user to be associated with a trusted connection?
The odd thing in my setup is that I'm using the exact same username and password as I'm using to connect to the database with Visual Studio 2005 and that works fine. But when I try the same acct/pwd from asp.net, I get that error.
FWIW, here's my connection string:
"Server=192.168.1.47; Database=MyDatabase; UID=MyUser; PWD=MyPassword"
What gives here? Any thoughts? Thanks!

I setup a DSN to a remote SQL 2000 Enterprise Server and was able to successfully complete the test connection. However, when I went to use the DSN to establish a connection in Integration Manager for GP 8.0 I got the following error:
"Integration Manager was unable to obtain column information.
You will not be able to map to fields in this query until the following problem is corrected:
Could not create connection to Data Source '_Web Customers':
Attempt to open connection Failed:
[Microsoft][ODBC SQL Server Driver][SQL Sevrer]Login Failed for user'(null)'. Reason:Not Associated with a trusted SQL Server connection."
I have tried everything I have been able to find on Trusted Connections but nothing seems to work.
Any ideas or pointers on where to look for help with this?
Thanks in advance for any help
