Login Failed For User '(null)' Error When Opening A SQL Connection

Jan 16, 2005

Hello everyone. I'm very new to asp.net. I've been coding in vb.net for a while now (getting my associates degree in desktop application programming) and my boss wants all of my new applications to be web based now. Well, i decided to take some initiative on this and begin a new project for my department. This is a very small project. So far, everything is coming along alright (i found an eBook that's helped me quite a bit). Everything was cool until yesterday when i tried to connect to our sql server database. I get an error message stating:





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





Because i'm testing this on my system as well as the remote system which hosts the application, i can see the error message on the remote system. Here is the error it's giving me:





Server Error in '/' Application.

You can see my SQL Connection string in there as well. Can someone please help me with this? I can post the code to the entire page as well if that would help. I'm developing this with Dreamweaver MX 2004 (i like dreamweaver MUCH better than visual studio, especially for web design/development). Thanks,

Trusted SQL Connection Impersonation And Login Failed For User '(null)'.

May 24, 2006

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 Am Also Getting: Login Failed For User '(null)'. Reason: Not Associated With A Trusted SQL Server Connection.

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.  Im not sure on what is going wrong here so I am at the mercy of asp gods of this site , below is some more info.

Login Failed For User '(null)'. Reason: Not Associated With A Trusted SQL Server Connection

Jan 18, 2007

Hi I have am developing on xp machine with iis 5.1 and trying to connect to a seperate windows 2003 machine with mssql 2000 installed.I would like to use a trusted connection and I added an asp account on the sql server with permissions to the database and also edited the security tab on IIS to have this account. I unchecked allow IIS to control this password.  When I look in the event viewer on my local machine I get an error:Process information:     Process ID: 2388     Process name: aspnet_wp.exe     Account name: MACHINENAMEASPNET  Exception information:     Exception type: SqlException     Exception message: Login failed for user '(null)'.

Login Failed For User '(null)'. Reason: Not Associated With A Trusted SQL Server Connection.

Mar 26, 2007

Basic setup

IIS 6 with ASP.Net 2.0, Integrated Windows Authentication turned on (anonymous turned off)
SQL Server 2000 with Windows Only Authentication on (SQL Server authentication turned off)
web.config file contains the following relevant entries:<identity impersonate="true" /><authentication mode=Windows" />
connection string:Data Source=[server name]; Integrated Security=SSPI; Initial Catalog=[database name];
When I run my query on my development server, it runs perfectly. When I run it on the production server (which is just an exact xcopy of the development web site), I get the "Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection" error. I have verified that the settings I listed above are the same on both sites. What else should I check for?
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:
string authUserName = User.Identity.Name;string aspUserName = System.Security.Principal.WindowsIdentity.GetCurrent().Name;Response.Write("You are: " + authUserName + "<br/>");Response.Write("This page runs as: " + aspUserName);

Login Failed For User '(null)'. Reason: Not Associated With A Trusted SQL Server Connection

Mar 23, 2008

I dont believe that no one can help me in this damn error,Please, I'm gonne lose my job offer If I didnt fix this. I have spent 7 days searching with no use !!
I use ASP.NET 2.0 with C# to develop an intranet site, it was working perfectly when i was on Visual Studio, when i tried to publish the site it gave me that error.
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
the web application on IIS server, windows 2003 - the database on a different server windows 2003, sql server 2000.
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
My connection string is:    <add name="LocalSqlServer" connectionString="Data Source=database server IP; Initial Catalog=database name; Integrated Security=True"; UID="sa" ; pwd="password";      providerName="System.Data.SqlClient" />Please find me a solution

Login Failed For User '(null)'. Reason: Not Associated With A Trusted SQL Server Connection.

Jul 20, 2005

Anyone,I have a user "john" whose machine is part of the "job" domain. He istrying to establish an odbc connection to an MS SQL 2000 server on the"school" domain. He uses Windows authentication to establish the odbcconnection however it gives the error "Login failed for user '(null)'.Reason: Not associated with a trusted SQL Server connection."I am guessing that the odbc connection is trying to pass thecredentials of jobjohn to the sql server. And since the sql serveris on the school domain it expects the credentials of schooljohn. Isthere anyway to specify the username and password so that this willwork even though the servers are on different domains without havingto trust the domains? Thanks in advance forany help on this!!Tony

Err Msg: Login Failed For User '(null)'. Reason: Not Associated With A Trusted SQL Server Connection.

Mar 28, 2008

Hi, I have been working on this for a few days now. Read enough searchs on line. Still not working.

I have a web IIS 6.0 server and sql server 2005 both on the same Windows 2003 server. I have an ASP.net 2.0 application try to access the database, getting the error message as describer above.

By the way, the app is an internet application, so can not using window integrated security.

The config for the ASP .net application is like this:
Enable anonymous access using the IWAM_machine local account.

None of the authentication method is checked.
The app pool is also set to use the identity of the IWAM_machine account.

In sql server, using the mixed mode acess.
Added the IWAM_machine account, granted the account access to the databases needed

The app web config is set as:

<identity impersonate="true"/>

<authentication mode="Forms">

<forms name="ApplicationAB.ASPXAUTH" loginUrl="/ApplicationAB/login.aspx" />

</authentication>


<appSettings>

<add key="conString" value="Data Source=XXX.XX.XX.XXX;Initial Catalog=MyDB;Integrated Security=SSPI"/>

</appSettings>



Could you please help?!! I am really frustrated with this.

Thanks a million.

SQL Security :: Login Failed For User Null / Not Associated With Trusted Server Connection

Login Failed For User '(null)'. Reason: Not Associated With A Trusted SQL Server Connection.

Dec 11, 2007



My company is using classic asp pages for clients to sign in. A COM object is used in the page to do members and lists management job. The database server(SQL 2000) and web server(Windows server 2000) are on different machine.

Now I am laungching a project which wrap the COM into class so that we can upgrade our existing webforms to .net based. The folder which runs the .net website is set as anonymous access, and the username is set to a domian user as "POOHCORNERUM52API". I ran an asp page which is ok.

However if I runs an .aspx page even with very simply sentences It runs into error page like:
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.

I googled on the internet, some pages suggest that .net pages are running under aspnet account, we need to impersonate to run that page with €œPOOHCORNERUM52API€? account, but the problem still exists even we do that impersonating like this:


<identity userName="poohcornerUM52API" impersonate="true" password="xxxxxxx" />

And on the SQL server I can see the user poohcornerUM52API is existed in the logins:

POOHCORNERUM52API Windoes User Permit master English

I ran the SQL profile to filter those with fail logins, and the event is captured however the field NTUserName and LoginName fields are empty.

Since I have done the impersonating, the page is running with the user "POOHCORNERUM52API", why those two fields are empty? I guess that is why the error come from.

If any one can help me out of this problem will be greatly appreciated.

Login Failed For User '(null)'. Reason: Not Associated With A Trusted SQL Server Connection.

Oct 24, 2006

I am receiving the following message when connecting via query analzyer to SQL server using windows authentication.(error 18452). I have a login created with the sys admin server role on the server. When I connect using SQL authentication it works.

I added myself to the local admin group on the server, this allows it to work. The same situation is seen with another user.

I am using windows 2000 sp4 server and SQL 2000 SP3, connecting from NT4. I get the same issue if I use TCP or named pipes. We have been using SQL security but are moving to windows authentication - but this issue is stopping us.

I have checked and upgraded my version of MDAC to match the server version 2.7 (sp1)


Any help would be much appreciated.


Thanks

Err Msg: Login Failed For User '(null)'. Reason: Not Associated With A Trusted SQL Server Connection.

Mar 26, 2007

I have a single user receiving this error msg on a web page of our Intranet web app after they change their password.  The user can access the web app just fine until they interact with this particular page.  This page accesses the database while data is entered via an ADO connection.  (Classis ASP)

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

The user has recently received a new desktop and the problem persists.  The database login account created for the user has been deleted and recreated with no change.

We are running SQL Server 2000 with SQL Server and Windows Authentication enabled.

Connection string: Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=ProductionDatabase Data Source=ProductionServer

Our solution has been to change the user's password back to their old password.

Any ideas?

Thanks.

Edit:  I am not entirely sure this is a SQL Server issue but I am starting here.

Login Failed For User '(null)' Error When Trying To Use Windows Authentication

Feb 6, 2006

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?

Error Login Failed For User ''. The User Is Not Associated With A Trusted SQL Server Connection.

Feb 18, 2008

All the research I found dealing with this problem is that the solution is to set SQLserver to mix mode.  I have SQL server already set to mix mode. I am not sure what else to do. Has anybody run into this problem?
my connection string: <connectionStrings>
<add name="ConnectionString" connectionString="Data Source= server name ;
Initial Catalog=FILESHAREDB.MDF;
Integrated Security=false;"providerName="System.Data.SqlClient"/>
</connectionStrings>
 
Server Error in '/SendItNow' Application.

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

Mar 11, 2008

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 : Cannot Open User Default Database. Login Failed. Login Failed For User 'server/user'

Nov 22, 2007



i'm using the Enterpirse library logger to write logs into a database.
When choosing connection string i choose the database i want in the "connection properties" dialog box and
push 'Test connection' button.
everything goes well.

then i open the SQL Server Management studio express and connect to the databse to check some things,
from that point on , when i push the 'Test Connection' button in the Enterprise library i get the error:


"cannot open user default database. Login failed. login failed for user My'server/MyuserName'"


even when i close the sql server manager , it is still stuck - the connection test doesn't work anymore....
it only work when i restart the computer.

why ?

Login Failed For Trusted Connection Login Failed For User 'NT AUTHORITYANONYMOUS LOGON'

Mar 13, 2007

We have a SQL 2000 Active/Passive cluster running on Windows 2000. On one node, everything logs in fine (second node is powered off). I can use local authentication fine in OSQL (-E) and even see my connection in SQLEM current activity as [DomainUser] for the NT account which I am logged in as. Then I bring the second node online and initiate a failover. SQL Server starts but Cluster Admin cannot connect and starts throwing this Anonymous Logon error. I open a command prompt and try the same OSQL (-E) local login and sure enough it is also giving the Anonymous Logon connection user. I do not understand why the failover to a second node is causing the Trusted Connection Local authentication to switch to Anonymous instead of the [DomainUser] which I am using. Any help is appreciated. John.

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]

Login Failed For User '(null)'.

Aug 1, 2007

 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.
 
thanks,
xyz789
