Backup Command Not Working - Not A Trusted SQL Connection

May 13, 2008

Hi there, I'm not exactly sure where to post this question, so I'll post it here.

I have 2 Windows XP machines, not part of a network domain. One of the XP machines is running SQL Server 2005 Express edition, lets call this DB machine. The other machine is just running my application - App machine. As part of my application, I want to be able to do a backup of the database.

The DB machine is also running the application. If I log into my application on the DB machine using SQL Server Authentication, and run the backup it works fine. (It's using the T-SQL BACKUP command). If it log into my application on the App machine, and try to do the backup, I'm getting an error saying that "The user is not associated with a trusted SQL connection". The same user is being used in both scenarios, and this user can update the database fine on the App machine, so it's not really a connection problem, it seems a permission problem. The SQL user I have created is a member of the db_backupoperator role for the required database.

Is anyone aware as to why I would be getting this error?

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.

SQL Connection In Vista With Trusted Connection Fails Under Local System Account Until Reboot

Mar 4, 2008

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.

Jdbc Refuses Connection With 'user Not Associated With A Trusted SQL Server Connection' Message

Jul 10, 2007

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?

SQL 2012 :: Error (backup Failed To Complete The Command BACKUP LOG) In Event Viewer

Aug 23, 2013

On the SQL Server the Event Viewer shows the same messages and errors every evening between 22:05:00 and 22:08:00. The following information messages are shown for every database:

"I/O is frozen on database <database name>. No user action is required. However, if I/O is not resumed promptly, you could cancel the backup."

"I/O was resumed on database <database name>. No user action is required."

"Database backed up. Database: <database name>, creation date(time): 2003/04/08(09:13:36), pages dumped: 306, first LSN: 44:148:37, last LSN: 44:165:1, number of dump devices: 1, device information: (FILE=1, TYPE=VIRTUAL_DEVICE: {'{A79410F7-4AC5-47CE-9E9B-F91660F1072B}4'}). This is an informational message only. No user action is required."

After the 3 messages the following error message is shown for every database:

"BACKUP failed to complete the command BACKUP LOG <database name>. Check the backup application log for detailed messages."

I have added a Maintenance Plan but these jobs run after 02:00:00 at night.

Where can I find the command or setup which will backup all databases and log files at 22:00:00 in the evening?

Trusted Sql Connection

Jul 3, 2001

Hello,

I have just installed MSSQL 2000 on Windows 2000. what I am finding is that I cannot open an isql (or query analyzer) session using the sql login (i am successful when i use NT authentication). The error message I get is as follows

Msg 18452, Level 14, State 1:
Login failed for user 'xxx'. Reason: Not associated with a trusted SQL Server
connection.
DB-Library: Login incorrect.

MSDN talks about setting the registry entries differently, but that seems to be only for SQL 7.

anybody have any hints about this.

Non-trusted Connection What Does It Mean?

May 5, 2004

What does it mean when a users is connected but it is a "non-trusted connection". This is showing up in the log file after my users connect. How does this effect the system/user? We have been experiencing speed issues and I was wondering if this might be a possible source of the problem.

Thanks in advance.

Trusted Connection From VPN

Dec 15, 2007



Hello,

I have an application we use here at work that I wanted to bring home to work from my house. At work I can get the application to connect to the SQL Server without problems. At home I get:

Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.

I am connected to the office using a VPN connection. I have permissions to access the database (I am the server admin). It only happens when I connect thru VPN. I have tried it on 2 other systems here in the house to insure its not just my computer.

At the moment the application will only work with a trusted connection or Windows Authentication. It will not work with SQL authentication.

Any ideas?

Thanks!

Connecting Using A Trusted Connection

Jun 29, 2006

Hello,
I appologize if this is in the wrong spot, but it seemed like the appropriate place.
We have IIS installed on one box and SQL on another. We use a trusted connection to connect.
When we try an connect to our DB, we don't get an error, the page just refreshes. From what i have gathered, it looks like we are not being authenticated. We have the ASPNET domain user on both boxes and its configured with the correct permissions, but we still can't connect.
Do i need to set up or give permissions to another account i dont know about, or is there some file that needs access?

Not Associated With A Trusted SQL Server Connection (Please Help)

Apr 2, 2008

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

Trusted Connection Problems

May 30, 2004

Hello everyone,

I am trying to use a trusted connect to connect to a DB. Currently I use this code:

WindowsPrincipal wp = (WindowsPrincipal)HttpContext.Current.User;
WindowsIdentity id = (WindowsIdentity)wp.Identity;

// impersonate user to connect to DB
WindowsImpersonationContext impersonatedUser = id.Impersonate();
try
{
connection = new SqlConnection("Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=DBname;Data Source=server;Packet Size=4096;");
dataAdapter = new SqlDataAdapter("select query");
data = new DataSet();
connection.Open();
dataAdapter.Fill(data);
connection.Close();
}
finally
{
// restore our old security context
impersonatedUser.Undo();
}

I am testing the app with my user which has full access to the server and database I am trying to connect to. But I always get this error:

Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.

Now I'm new to this and not sure if I am going about it correctly, so any help would be appreciated. I just want it to use the ID of the person viewing the page to login to the server.

Thanks,

Luke

Trusted SQL Server Connection

Nov 16, 2000

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.

Obtain Trusted Connection ?

Feb 2, 2006

Hi all!


I have a new computer, clean, I installed WinXP, and I want to connect a SQL Server (other computer in the same network)
For this I installed the client tools from SQL SERVER 2000 kit. Ok.
When I try to connect to the server, I can't connect through "trusted connection", only whit user name and password.
I mention that I set the sql server in mixed mode autentification.

When I try to connect from other computer (my laptop, or other computer from this network) I can connect both types of connection: trusted and with

sa (for example)

The question is:

How I can set up a "trusted connection" at SQL Server?



The computer is completely new, clean and has win xp with sp2.


Any opinion are considered.

Thanks in advance.

SQL Server And Trusted Connection

Feb 26, 2002

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.

Not Associated With A Trusted SQL Server Connection

Feb 11, 2004

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.
