When accessing a web application from an intranet....
And the web app tries to make a connection to a 'SQL Server' using the sqlconnection where does ASP.NET grab user credentials?
My webpage displays web security.principal.windows.getcurrent = domainUser (displays the correct information).
But the connection to sql says Null. Where is ASP.NET grabbing (retrieving) this information from?
Thanks,
what does this imply Trusted_Connection=true parameter in the Connection String signify?
Secondly how can I make users with Windows Authentication Login to work in SQL Server Connection String?
Thanks in advance,
Neeraj.
Hey. I need to substitute a value from a table if the input var is null. This is fine if the value coming from table is not null. But, it the table value is also null, it doesn't work. The problem I'm getting is in the isnull line which is in Dark green color because @inFileVersion is set to null explicitly and when the isnull function evaluates, value returned from DR.FileVersion is also null which is correct. I want the null=null to return true which is why i set ansi_nulls off. But it doesn't return anything. And the select statement should return something but in my case it returns null. If I comment the isnull statements in the where clause, everything works fine. Please tell me what am I doing wrong. Is it possible to do this without setting the ansi_nulls to off??? Thank you
set ansi_nulls off
go
declare
@inFileName VARCHAR (100),
@inFileSize INT,
@Id int,
@inlanguageid INT,
@inFileVersion VARCHAR (100),
@ExeState int
set @inFileName = 'A0006337.EXE'
set @inFileSize = 28796
set @Id= 1
set @inlanguageid =null
set @inFileVersion =NULL
set @ExeState =0
select Dr.StateID from table1 dR
where
DR.[FileName] = @inFileName
AND DR.FileSize =@inFileSize
AND DR.FileVersion = isnull(@inFileVersion,DR.FileVersion)
AND DR.languageid = isnull(@inlanguageid,null)
AND DR.[ID]= @ID
)
go
set ansi_nulls on
I have a cube that has a Dimension set up with several values some of which are bools. While Browsing in Excel or SSMS, two new values, when used as a filter shows (All) (Blank) and (True) for selections instead of (All) (True) and (False).

I have been using an Access DB until now and am going to start looking at using an SQL Server instead. My first task was to make sure that I could connect. I created a basic DB and created and added a user as public, datareader and datawriter.
My first attempt at a connection string was -"server=local;uid=someuser;pwd=password;database=basic"and it couldn't find the server (I tried 'localhost' as well).
My next attempt was -"server=QTLAP01;User ID=someuser;pwd=password;database=basic"And I got the error "Reason: Not associated with a trusted SQL Server connection.".
I eventually found that the following worked -"server=QTLAP01;User ID=someuser;pwd=password;database=basic;Trusted_Connection=true"But, I don't understand why. Why would it believe that the connection was trusted just because I said it was?
Thanks

PS the computer in question is not connected to a network so no problems with username and password security.
I have an issue dealing with connectivity between the client and Sql Server Services or Sql Authentication. I keep receiving this type of error message:Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
I am sure my connection string is correct within my web config file, I have something like this:Data Source=myServerAddress;Initial Catalog=myDataBase;Integrated Security=SSPI;
The reason why I think the connection string is correct is because I have a server where my asp.net application is stored and used, this server is called server1. Server1 is connected to MS-SQL server that is installed and used on server2. When I run my application from server1 everything is perfect, nothing goes wrong, but when I run the application from my client or local machine I get the error message saying not associated with a trusted site.
Now I have the web config set to <identity impersonate="true"> that will allow windows Authentication, and I set the permissions within the database to use NT AUTHORITY NETWORK SERVICE as a user, plus my own network credentials are set within user on the database, just so I could troubleshoot the problem. But I still get the error message not associated with a trusted site.
Just to recap my problem, I can see the data when I run the application in Server1, but I can't see the data when I run the application from my local machine. http://server1/MyApplication.aspx <-- this is an example of the url that I enter on my local machine to acces the application. Plus I have full acces to server1, and other application are running just fine from this server.
I am using visual studio 2005, but using sql 2000, with the latest service pack for windows XP pro.

SQL7 server is configured to use both SQL and NT authentication. Periodically, NT authenticated users get the error "Login failed for user '(null'. Reason: Not associated with a trusted SQL Server connection."
Repeating the login will eventually end in success.
Microsoft article Q216848 indicates this has something to do with the version of MDAC.
We have not changed the version of MDAC on the server, but checked it and the versions are as the article states (MDAC 2.1 & SQL Driver 3.70.623).
We had a newer version on the client, but went back to the version above that came on the SQL7 CD with no luck.
Any ideas, suggestions, or similar problem experienced?
Thanks in advance.

I'm new to Crystal Reports and ASP and I'm sure i'm missing something simple here.
I've got a SQL server database, A Crystal Report, a VB application and an ASP Application
In the VB app i call the crystal report and log on to the database with the intergrated security
However in the ASP app i try the same and it has me log on as a null user.
what have i forgotten to do that will let the intergrated security work between SQL Server and ASP
I recieved this error in my logs:
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
It appeared nearly 20 times, then about 30 minutes after the first occurence, I noticed in my Event Viewer this error:
The registration of DNS name XXX.XXX.XXX.XX.in-addr.arpa. for network name resource 'SQL Network Name(SQLServer)' failed for the following reason:
DNS operation refused.
After that I began recieving hundreds of errors like this one:
Login failed for user 'SQL user'. Only administrators may connect at this time.
I was unable to connect to the server to see what was going on so I had to failover the server. That's why my troubleshooting is limited to error logs. After the failover, everything came up fine with no more errors. Has anyone ever encountered this before?
BTW, This is a SQL 2000 Cluster on Windows 2000.

When I user SA, I do not get the above error.
Any clarifications on the possibilites for getting the error is appreciated.

Hi.
Im trying to make a couple of reports online for other people. My current setup is:
Machine A: SQL05 server.
Machine B: ReportingServer05 and IIS 5.0 (XP machine).
Machine C: Client trying to connect to Machine B and view a report. (Windows 2003)
On Machine B everything is working just fine, i can view my reports without any problems.
But if i try viewing a report on Machine C, I get the following error:
An error has occurred during report processing. (rsProcessingAborted) Get Online Help
Cannot create a connection to data source 'IntegrationDB'.
(rsErrorOpeningConnection) Get Online Help
Login failed for user '(null)'. Reason: Not associated with a trusted SQL
Server connection.
But machine C kan browse http://machine-b/ReportServer and se the list of reports hosted, its when trying to generate the reports there is a problem. Im logged in on machine C with the same user as on Machine B.
My Shared Data Source in this VS05 project is setup to be using Integrated Security, so the "user '(null)'" part looks like Machine C dosnt supply the username, but why?
What is it that im missing in my configuration?
And any addional information needed?
Best Regards.

Hi,
(First, I should explain that I am not sure whether this is the right part of the forum for this message. My apologies if I'm in the wrong place. If this is the case, could you please let me know where this post should be? Thank you.)
I have a vew that accesses data from a linked server. The view works properly in Query Analyzer but fails when run by a .Net application. The message returned is:
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
The linked server has the following attributes:
Server Type: SQL Server
Security: No local logins listed. Connections are made using the login's current security context.
Any help would be appreciated. Thank you.
I've read quite a few articles about resolving this login problem. "Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection. " But still can't solve mine.
I am working on a Website that can access a remote database engine which locates in the same domain. (Eventually the website and the db server would be on the same computer, but not during the development and testing.)
My code works fine when I am debugging on an ASP.NET Development Sever. I tried two users account, Windows' or SQL Server's. Both work fine under ASP.NET development server (run ASP.NET application locally).
But when I run the website from wwwroot virtual path, it throws error message:
"Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection."
Why does it this happen? And how to resolve this? Did I miss anything on local IIS side or the remote DB server?
Thanks.

All,
In Microsoft analysis services, I get an error that login fails for user "NULL" when I try to process/build any cubes. If I edit the connection properties, it says to use "trusted" signon. If I press the "test connection" button all is well.
I definitely have serverdatabase access otherwise. Any thoughts/insights?
Thanks,

Hello everyone. I'm very new to asp.net.

I'm working on an ASP.NET project, and we're attempting to switch from SQL Server authentication to Windows authentication to connect to the database.
It works fine locally when I debug in Visual Studio, but when it hits the web server, I get the error: "Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection."
IIS has anonymous access disabled, and Integrated Windows Authentication is checked. The web.config file has:
<authentication mode="Windows"/><identity impersonate="true"/>
The database I'm attempting to access is on a different machine than IIS, and the connection string doesn't contain a username or password, and has "Trusted_Connection=Yes", and "Integrated Security=SSPI".
From what I've been able to find online, I'm guessing the problem is due to IIS and SQL Server residing on different machines, but I'm not sure how to fix it.
Any ideas?
Hello All,
Login failed for user '(null)'.
I know this issue is all over the forum, however i have not found any posts that help me resolve the issue.
Situation:
I have an ASP.NET 2.0 application hosted currently on XP pro(will be moving to 2003 Server) which connects to a SQL 2000 database that resides on a different server. I have taken the following step to implement my security.
Given my account permissions to the database
Put the following in my web.config
<add name="MyName" connectionString="Data Source=MyServer;Initial Catalog=MyDatabase;Integrated Security=SSPI" providerName="System.Data.SqlClient" />
<authentication mode="Windows" />
<identity impersonate ="true" />
I have set IIS to use integrated authentication and removed anonymous. The application works when run from the web server but not when run from a remote machine.
Thank you for any asistance,
George
I have an identical SQL database on two machines (my machine and a webserver) that links to a database on a third server (S3). When I executea stored procedure on my machine that accesses a database on S3, italways runs without a problem. However, when I run the same storedprocedure on the webserver (via Query Analyzer on my machine, connectedto the webserver), the stored procedure runs without a problem forabout ten minutes, and then I suddenly receive the error "Login failedfor user '(null)'. Reason: Not associated with a trusted SQL Serverconnection.". If I then connect remotely to the webserver via RemoteDesktop Connection and run the stored procedure there it works, andthen I can run it again on the webserver via Query Analyzer on mymachine, but the same problem will occur again after about ten minutes.The only difference between my machine and the webserver is that thewebserver is running Windows Server 2003, whereas my machine runsWindows XP. All settings in SQL on the two machines are identical, so Iwould love to know if anyone has a possible solution to this seeminglyrandom problem.

I have an application which uses a login with an encrypted password. Everything works well, no errors in the application.
My SQL Server errorlogs keeps recording:
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
I know this message is related to the login with the encrypted password (tracked it with Profiler)
My question: Is it normal that the error log tracks this message because the password is encrypted?
Many thanks!

Hi, am having the error above in my Subject Line. I seem to have the problem on my host web service, they have IIS 6.0 on a 2003 Server, and SQL 2000 and SQL 2005 on another server that I connect to seperately. I am using asp.net 2.0 and SQL 2000 Desktop version. I am in the very basic beginning of this website development, all I am trying to accomplish here is to enter in a login and password and be redirected to another webpage. This works on my local laptop with XP Pro, but when I try it on the server that I host my website on, I am getting this error.

I placed some test code on the page that outputs the current logged on user and the current asp.net user, and everything seems fine (both usernames are the same - the expected domainusername of the impersonated user who logged in to the site), so I don't know why the database would say the user was null. My test code for outputting the user is below:

Regaeding that we have proxy server, one firewall.
I tried to do the following steps with no use :(
1. Create a Domain Account with priveleges similar NETWORKSERVICE (windows server 2003).2. Grant this Domain Account (DomainName/NETWORKSERVICE ) access in the SQL Server Database for the necessary databases (created a new login for this user and gave it the privillage creator, read, write)3. <identity impersonate="true" userName="DomainNameUserName" password="password" />The second method is to simply set identity impersonate to true and assign the username and password in the IIS.1. Type inetmgr from your command prompt and give enter.2. This would open the IIS Control Panel.3. Expand the appropriate nodes and select the Virtual Directory of your application.4. Right Click and select Properties.5. Switch to the Directory Security Tab.6. Under Anonymous access and authentication control click Edit7. Check the Enable Anonymous access in case you want people to access the application without logging in with Windows Logon Screen.8. Uncheck the Allow IIS to control password and enter the DomainName/UserName and Password in the respective boxes. Usually IIS uses IUSER_MACHINENAME credentials for Anonymous access.9. Uncheck if any other authentication mode is checkedI did the previous step exactly like that. and the error still come.I remind you again we have a proxy server with one firwallI dont running under https X
