Security.Principal.Windows: mydomainmyuserid (this is correct what it shows on my page)
Me.User.Identity: mydomainmyuserid (this is correct what it shows on my page)
Threading.currentThread.currentUser mydomainmyuserid (this is correct what it shows on my page)
So the ASP.NET page recognizes it is me and my domain. However, when i click a button to pull some data from a database I get the error message: Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
My data access on SQL Server works fine. The weird thing is when I debug on my machine it pulls data fine. but when I copy the files to the windows 2003 server it doesn't work.
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?
We are looking at developing an SQL Server 2005 Database and I would like to use Windows Authentication rather than SQL Server Authentication to connect our client app.
In our development environment, we have two Servers, one being used as a file server and the other as an SQL Server. We have now set up a domain using the file server as the domain controller. (We had previously been set up to use a workgroup).
I have set up an active directory group called SqlDevelopers and added an active directory user called Jonathan to it.
On the SQL Sever, in management studio, I have set up a new server login which uses windows authentication called DomainSqlDevelopers. I used the GUI to verify I could see the domain and the group.
The default database is set to a test database on the server. A user in the test database is mapped to the DomainSqlDevelopers and given the Roles dbo, db_datareader, db_datawriter.
To test the log in, on the server, I logged out as administrator and in as Jonathan. I could successfully access the server through management studio using windows authentication.
However, if I log in as Jonathan on my client PC and try to access the SQL Server using management studio and windows authentication, I have problems.
The first time I try I will get a timeout error. If I try again will get either:
Login failed for user ''. The user is not associated with a trusted SQL Server connection
Or
Cannot generate SSPI context
I can€™t determine any pattern to which of the above errors I get.
However, if I log in as administrator on my client PC, I can connect to the server using management studio and windows authentication.
Sounds like Active Directory/Domain or other Network issue (Not really my area). I would be grateful for any help.
Oracle and Teradata are able to capture the windows/client login that connects to their database with a functionnal ID.I've searched around and I don't think MS SQL can do this...I administer SQL 2014 server and also SAS Enterprise guide product. I've created sql server logins for several teams so everyone shares the same sql server login which is used to bind the SAS library to my SQL server database.
However, when looking at activity monitor, I can't drill down to which user is executing a particular query. I only see the SQL login which is share amongs 200 other folks.On the other hand, when they connect from SAS to Oracle or Teradata, I can see the shared login + additionally their windows NT login used to connect to SAS which is awesome....they can't fool me by using a shared/funcionnal ID....i still see who's using that ID...
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.

Am I missing somthing here? Chrissrbytes@yahoo.com
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)'. Reason: Not associated with a trusted SQL Server connection. Any Ideas as to how I can fix this?
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);
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

Newbie here, so thanks in advance for any help. SQL Server 2000 on Windows 2000, Mixed Mode authentication IS enabled.
System DSN set on 8 workstations, a mix of 2000 - 98 and XP Pro
App uses DSN connection, specifies sa user and password. DSN's all set up the same, Client config is TCP/IP, SQL Server also set to only accept TCP/IP.
Trying to authenticate using SQL Server Authentication. XP Pro machines generate the above error. 98 and 2000 machines connect flawlessly.
I am stumped. Have read the MS knowledgebase articles, read threads here. Nothing seems to apply. It's an Internet app, so using Windows Authentication is not desired. I just don't understand why XP pukes while the other MS platforms connect just fine.
If anyone has any thoughts, I'd appreciate suggestions!
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
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
Any way to find out who's causing "Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection." error in SQL Server error logs?
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:
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.
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)
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.

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.

Would be interested in any advice or comment on the issue we are experiencing with SQL 2005.
In order to test some DTS package migrations, we simply created a DTS package on SQL 2000 (using Export) to copy all database objects from one database to another.
Then we restored the source database on SQL 2005 server, migrated the DTS package, and tried to execute it.
The package migrated 'fine', ran part way, and then failed. Since then we have been unable to connect to the server (Database Engine, or Integration Services) using Windows Authentication. (Error 18456, Sev 16, State 11).
We can connect to the Database Engine using SQL Authentication (but not to Integration Services which only allows Windows Authentication).
We have been able to replicate this consistently - every annoying time we've tried it!
(Reinstalling SQL Server does 'fix' the issue ... until you try a similar package again).

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.

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?
