I am having a very strange and frustrating problem with moving an application from Development to Production. I have been working on this application on XP with VS2005 with SQL Express on my local machine. Throughout the development lifecycle I have moved it to the Server multiple times to test things and everything has been working fine until this last time. What I have done since the last time: Added some ASP.NET AJAX functionality Added some views that I am having to fill a dataset from the dataset to manipulate the data before presentation. Everything has worked fine without any issues on my local machine with my local database. I just made backups of the databases and restored them on the server and have moved all my project files up to the server. I then installed the ASP.NET AJAX Extensions 1.0 on my 2.0 server.
NOW - The Problem: The entire site works fine, I can read data from every table of every database, and I can also write data to all the databases. However, this one page has a GridView that I pull data from the database and fill a DataSet with the data. I then manipulate the data, adding some data from other databases and then present it to the browser. This is working fine on my local machine, but since pushing this to the server I get an error: System.Data.SqlClient.SqlException: Login failed for user 'ext_access' Line 36: ad.Fill(ds, "CaskInfo")Line 37: Dim Table As DataTable = ds.Tables("CaskInfo")Line 38: Table.Columns.Add("Company", GetType(String)) I have checked the database and the SQL Server and the user listed above has the correct access to the database, which I would guess since everthing else is working fine. I use the same connection information throughout the app and it is stored in the web.config so I am certain nothing is wrong with my connection information. I access that information with the same code throughout the application as well so I know it is correct. I know this may not be the most trimmed piece of SQL code, but I figured I would post it incase there is something inefficient in my SQL that could be causing this. Here is my code leading up to the error. Dim conn As SqlConnection = CreateConnection2()Dim connectionString As String = conn.ConnectionString Dim myConnection As New SqlConnection(connectionString)Dim ad As New SqlDataAdapter("Select CaskID, CompanyID, SiteID, UnitIDVCC, UnitIDTSC, DATEPART(mm,DateLoaded)as Month, DATEPART(dd,DateLoaded)as Day, DATEPART(yyyy,DateLoaded)as Year, COCName, AmendmentName, HeatLoad, Dose, DryTime, Damaged, Debris FROM CaskInfo, COCInfo, AmendmentInfo WHERE CaskInfo.COC = COCInfo.COCID AND CaskInfo.Amendment = AmendmentInfo.AmendmentID", myConnection) Dim ds As New DataSet() ad.Fill(ds, "CaskInfo")
Using this connection code:Function CreateConnection2() As SqlConnection Dim conn2 As SqlConnection = New SqlConnectionconn2.ConnectionString = ConfigurationManager.ConnectionStrings("MainWeb").ConnectionString conn2.Open()Return conn2 End Function And this is the line in the web.config: <add name="MainWeb" connectionString="Data Source=N2K3APPS;Initial Catalog=NUTUGData;Integrated Security=false;Pooling=False;User Id=ext_access;password=zzzzzzz" providerName=".NET Framework Data Provider for SQL Server"/> Thanks!
I have searched all the forums on this issue and tried the other options but nothing seems to work. I have an IIS server using asp.net to connect to a SQL database on a separate server which also happens to be a domain controller(i.e. no local accounts). I have tried changing the connection string, web.config, etc. but I still can't get connected. I believe the issue is with the SQL security but I'm not sure.

Hi, I have a copy of VS2005 and i have installed the Microsoft SQL Server Developer Edition I am trying to do my first connection using ASP.net (yay for me...) and it has failed...with this error..Login failed for user 'testuser'. The user is not associated with a trusted SQL Server connection.
can someone please point out why? yes i know that the error seems pretty straight forward but how do i fix it? like how do i make the user a trusted server connection? where do i do it? and what are the steps? the user is an administrator and by rights should have all access to everything....
connection string
SqlConnection MySQLConnection; MySQLConnection = new SqlConnection("server=cmptrname\databsename;uid=testuser;password=password;database=mytest");
btw while your reading do you have any examples of opening a db with the connection string in the web.config file? because i get some error "connection string has not been initialised" using the system.Configuration.ConfigurationManager.AppSettings.Get i though i would stick to the top code first before i tackled the web config error first....
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>

Hi all, I am new in asp.net. In my web.config file, I wrote the connection strings as below and then I got the above error. I already changed SQL server Authentication mode to "SQL server and Windows". Any idea? Thanks in advance. <connectionStrings> <remove name="LocalSqlServer" /> <add name="LocalSqlServer" connectionString="Data Source=xxx;Initial Catalog=mydb;User ID=test;Password=test;Persist Security Info=False;" providerName="System.Data.SqlClient" /> </connectionStrings>
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.
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:
Date 10.03.2008 6:15:19 PM Log SQL Server (Current - 11.03.2008 2:32:00 PM) Source Logon Message SSPI handshake failed with error code 0x80090304 while establishing a connection with integrated security; the connection has been closed. [CLIENT: <IP Address>]
I've seen many, many, many, many posts regarding this topic - but none have been able to fully explain nor fix my problem.I've developed a security solution according to Scott Gu's guide and it works great - but only on my local machine running VWD and SQLExp2005. Once I move this application it completely breaks in the productions environment. Today I managed to get it halfway there. I created a SQL login and changed my web.config to use these credentials - now the web application will come up, but none of my links (that are role based) are displayed - most likely because i'm authenticating as the SQL credentials instead of me. So I switch it back to windows authenticated, as it is on my laptop, and it breaks again. Please tell me theres a way to get this working in production and Scott's fantastic tutorial hasn't wasted me 2 weeks of work. Here's the exact error I get when using Integrated authentication: Server Error in '/Contracts' Application.

Hi I'm making a website and will upload it next via ftp but i need to access the local server for database retrieval from this website. i'm doing so first time so not sure about its working and isues. Through google search and from forums i collect some info to work on it. now i have made a connection string to access remotely that gives the following error when i make the connection open "Login failed for user ''. The user is not associated with a trusted SQL Server connection." the local server use the windows authentication mode or may be the mix mode. Please any one can help me about this issue and further information related to it. and one more question, how much time a page takes to load while getting 600 records from a table in local server. thanx in advance
Arrgh! I've check and to make sure SQL Server and Windows Authentication option is selected. The user has Grant access to connect to database engine and Login is enabled...and also has database read/write privs. I can login using the username/password from Mangement Studio Express, but I can't from my app. Here is my web.config: <connectionStrings> <add name="CPT_ConnectionString" connectionString="Data Source=192.168.1.40ccsql1;Integrated Security=SSPI;" providerName="System.Data.SqlClient" /> </connectionStrings> <system.web> <identity impersonate="true"></identity> </system.web> The only thing I can think of is that my app is using a DSN to connect to the database. Any ideas? Many thanks, Mark

I have a windows 2003 server hosting MS SQL Server 2005. Another windows 2003 server hosting my App, and clients from the local intranet and outside (web). How do I surpass this problem, when it all works fine locally on my development machine?
We are wanting to use SQLEXPRESS in a workgroup called REALITY, no servers just PCs. I have four PCs in this workgroup and need them all to share the same database from one of the PCs. I can share folders and map a network drive but can not connect to the SQLEXPRESS database remotely.
I have set server authentication mode to Windows and SQL and have enable local and remote connections (TCP/IP only) in the surface area. After making these modifications I was able to connect to the database through the SQL Server Management Studio Express after I enable the guest account. When I first started I had numerous connection errors and have worked through them all by performing the above and was only finally able to connect after enabling the guest account and adding said account to the SecurityLogins. However, today I am unable to connect I have double and triple checked the settings and still continue to receive the same error.
I installed SQL Server express edition on my corporate desktop computer which is part of a Domain. When I installed it I set it up for mixed mode so I could log into SQL server directly or use Windows authentication. I use the management studio and log into the server using the sa account which I have added a password for but I can not log in using the Windows authentication. The error in the subject line of this post was copied directly from the error log as you can see the user name is null.
The following is more of the same log file it seems to start with the SSPI handsshake error. Does anyone know how I can troubleshoot this error?

I am trying to login to SQL Server 2005 using SQL Server authentication using 'sa' account but it gives the below error
'Login failed for user 'sa'. Not associated with trusted SQL Server Connection'
The authentication mode set for the server was 'Windows Authentication' so i tried to change that to SQL Server and Windows Authentication but it didnt allow me to change the mode. It gives the below mentioned error.
"An exception occured while executing the Transact SQL or Batch Statement. Execute permission denied on Object 'xp_instance_regwrite' , database 'mssqlsystemresource',schema 'sys' "
Could you anyone kindly let me how to resolve this issue so that i can connect to the SQL Server using sa account.
Can someone explain it to me why I am getting the following error when I try to connect SQL server express with .NET 2.0?

Hi when i try and open a database in sql server management studio i get the error "Cannot open user default database. Login failed. Login failed for user 'DOMAINUser'. (.Net SqlClient Data Provider)", what can i do to rectify this, i have googled around and still havent found no answers.
Login Failed for user , the user is not associated with a trusted sql server connection. (microsoft SQL Server,Error:18452)
hi , i am getting the above error message once in a while maybe two or 3 times a week , and then it goes away in 10 to 15 minutes or 5 minutes ,
our mode is set to mixed and we are able to connect and use both sql and windows , but once in a while , it will give us the above message when we try connecting throught sql server management studio client (using sql 05) using windows login , although it lets us connect using sql login while the windows login is denied, and after a while it lets us connect with both.
occurs randomly on some days , we run our servers on VM ware virtual machines using windows 2003 r2 enterprise 64 bit with sp2 with esx 301 virtual machine.
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]
Can anyone give a quick description of the meaning of this message andwhat needs to be done to get a connection.I'm running DBArtisan with SQLServer 2000 client SP4 installed.I also get the same message with MS Enterprise Manager so this iscoming out of the actual ODBC connection attempt.Thanks in advance!
