Login Failed For User 'NT AUTHORITY/SYSTEM'.
Jun 9, 2008
Hi,
I can view the site fine on VS developlement sever, but not through IIS 7. Whenever i try to run it, i get this error: Login failed for user 'NT AUTHORITY/SYSTEM'. The problem is that i am not using this user to access my database, so i don't know where it came from. I mapped this new user to my database and changed my web.config file accordingly to see if it works, but it did not.
i have looked high and low for this, but i don't seem to find a solution that solved my problem. I am running Vista, IIS 7 and have forms security on my website.
Any suggestions will be very much appreciated.

I have googled this to my hearts (dis) content, and all the answers I have found either rely on 1) creating untrusted connections, or 2) hard coding your password into the page. Neither of which I am satisfied with. Here is my scenario:I am using Visual Web Developer 2008 Express Edition to construct an intranet site on my companies corporate network. I am using a development PC which sits not far from the main server I will be utilising for the hosting of the intranet site. I have local admin privileges to this server (as well as the box I am developing on). I do not have privileges to the domain controller (but that doesn't seem important to me anyway).I have created a database in SQL Enterprise Server on the intranet server and am using that database thru my development box. ie, the (test) data is already on the server and I have VWD2008EE access the data directly. Now this works as expected and without problem. I can create data sources and controls and they work on my development box. I can create data access code that also accesses the database, and it works correctly, ie, I see the data. However, when I import the code/pages to the production server, I get this error message: Login failed for user 'NT AUTHORITY/NETWORK SERVICE'."What puzzles me is that the VWD development server can access the database without a problem, yet if the pages run from the server itself, the database is no longer accessible. And it is the same database we are talking about. Disabling any form of security is not an option.Also, Windows authentication (ie using the domain controller) is the ONLY for of authentication available to me.I am guessing I have to add a particular type of user to the production server, but where and how is a little beyond the scope of my knowledge. There is no "Network Service" user (should there be?)Any help would be GREATLY appreciatedFurther info if required:Development PC - Windows XP Pro SP2 on a corporate network, logging in through a domain controllerProduction PC - Windows Server 2003 Enterprise SP2 using IIS V6.0 and SQL Enterprise Manager 8.05.02 (ODBC V: 3.52.0000)This is the code I use to access the SQL server(remember, this works from the development PC to the production SQL server, just not form production PC to production server): Imports System.Data.SqlClientProtected Sub Page_PreRender(byval sender as object, byval e as system.eventargs) Handles me.prerender Dim dbcon as new SqlConnection("Data Source=F001;Initial Catalog=Whiteboard;Integrated Security=true;") Dim myCommand as new SqlCommand myCommand.Connection = dbcon myCommand.CommandText = "SELECT * FROM tbl_rooms ORDER BY [d_date], [r_id], [t_from]"
Dim myReader as SqlDataReader dbcon.Open() ' <-- this is where the error comes in ONLY on production PC '... code which reads the table and prints it (this works)
dbcon.Close
End Sub

I'm having an issue with .NET and SQL Express. I have a windows service application that retrieves data from a SQL Express database. The service Log On properties are set to log on as NT AUTHORITYNetworkService. The service works as expected in my test and development environment. I have tested this on XP SP2 and WIN2K SP4.
I installed this on a production machine, running XP SP2, and I get the following error:
Login failed for user 'NT AUTHORITYNETWORK SERVICE'. [CLIENT: <local machine>]
If I set the Log On properties for the service to "Local System Account", it works as expected.
I checked for any differences between my develpment installation of SQL Express, and the production installation, but could not find any descrepancies.
Does anyone have some suggestions?

When choosing connection string i choose the database i want in the "connection properties" dialog box and
push 'Test connection' button.

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....

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.
IIs is set up for Integrated Windows Auth.
Here is the web.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<!-- application specific settings -->
<appSettings>
<add key="connectionString" value="Data Source=VGISQL2;Initial Catalog=PaymentApplication;Integrated Security=SSPI;" />
</appSettings>
<system.web>
<!-- DYNAMIC DEBUG COMPILATION
Set compilation debug="true" to enable ASPX debugging. Otherwise, setting this value to
false will improve runtime performance of this application.
Set compilation debug="true" to insert debugging symbols (.pdb information)
into the compiled page. Because this creates a larger file that executes
more slowly, you should set this value to true only when debugging and to
false at all other times. For more information, refer to the documentation about
debugging ASP.NET files.
-->
<compilation

debug="true"
/>
<!-- CUSTOM ERROR MESSAGES
Set customErrors mode="On" or "RemoteOnly" to enable custom error messages, "Off" to disable.
Add <error> tags for each of the errors you want to handle.
"On" Always display custom (friendly) messages.
"Off" Always display detailed ASP.NET error information.
"RemoteOnly" Display custom (friendly) messages only to users not running
on the local Web server. This setting is recommended for security purposes, so
that you do not display application detail information to remote clients.
-->
<customErrors
mode="Off"
/>
<!-- AUTHENTICATION
This section sets the authentication policies of the application. Possible modes are "Windows",
"Forms", "Passport" and "None"
"None" No authentication is performed.
"Windows" IIS performs authentication (Basic, Digest, or Integrated Windows) according to
its settings for the application. Anonymous access must be disabled in IIS.
"Forms" You provide a custom form (Web page) for users to enter their credentials, and then
you authenticate them in your application. A user credential token is stored in a cookie.
"Passport" Authentication is performed via a centralized authentication service provided
by Microsoft that offers a single logon and core profile services for member sites.
-->
<authentication mode="Windows" />
<!-- AUTHORIZATION
This section sets the authorization policies of the application. You can allow or deny access
to application resources by user or role. Wildcards: "*" mean everyone, "?" means anonymous

<!-- APPLICATION-LEVEL TRACE LOGGING
Application-level tracing enables trace log output for every page within an application.
Set trace enabled="true" to enable application trace logging. If pageOutput="true", the

Hey Microsoft: this affects development that will eventually sell a lot of seats on SharePoint Server 2007. If you guys and gals can't straighten out this mess, you can't expect custom solutions with custom web parts. So pay attention for your own good. Yes, SPS 2007 is what this is all about. I've created simpe web parts and deployed them, same VS 2005, but I need local development and debugging for more complex stuff. I'm really disappointed that you have no solution for this problem.
I've seen other posts on this, but the result seems to be the same: if you fix it, it's by accident, not by design.
1. I created a blank ASP.NET web site
2. I added a web part manager
3. I added a web part zone
I get the error described above. I have no idea why SQL Server settings are so screwed up.
I've tried all the stuff in the other posts - security settings, command line installation, etc. None of those worked.
The default template(s) don't copy anything into App_Data, nor create an empty folder. I don't know why that is. I have other web sites working just fine, but they use remote SQL databases, or local ones I created, and didn't need profile management (no forms authentication, no web parts, no web zones).
I've also started out with a local database, using SQL Authentication, later moving it to a remote server, and never had any problems. The SQL Server developer edition and Express seem to work just fine. I can also debug stored procs when the .mdf is in App_Data. So the problem isn't one of connectivity.
What would cause the default screw-up? This would seem to point from all directions to a problem with Visual Studio (2005)? The installation is defalt - perhaps some extras included (copy local), but nothing unusual. AJAX for ASP.net is installed, but not used in the above "default web site" trial. Likewise Syncfusion's tools, which work fine on other developer workstations at this same location, all of which are from the same image (purchased at the same time & imaged). That web parts work on other boxes, running all the same management tools (anti-virus, remote sys admin/sms etc.) makes none of those suspect.
I think Microsoft needs to have a clean problem solution and publish it. SP1 certainly doesn't fix it. What's worse is the stupid, lame error message. "I can't open the default database". Well, what did you try? What do you think the default is? What settings are you using? Why is there no debugging information other than the usual worthless trace information showing it's all deep within the ProviderBase and SqlClient namespace code? How is that supposed to be helpful?
If anyone has anything solid, not guesses, I'd like to know.

hi,
so i have a new box and I'm trying to get my websites and SQL Server 2005 Standard Edition working on it, but the pages give me the following error when I try to load them:
"Cannot Open Database "XXXX" requested by login. The login failed. Login failed for user 'xxx'"
Everything seems exactly the same settings and user-wise from my old box to my new one, but nevertheless everything I've tried gives me the same error.
I've tried creating new users in SQL Server and giving them appropriate permissions to my database. I've even tried just using the built in 'sa' account. Nothing seems to change the error, except when I give it the incorrect password then it just says 'login failed'
This leads me to believe that i'm successfully logging into the SQL Server, but it doesn't want to give me access to the database I'm requesting access too. But "apparently" the account i'm using should have access to the database. If nothing else the 'sa' account should, but that didn't work either.
I'm stumped. Any ideas?

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.

Hi,
I wanted to check the asymmetric key option in sql 2005. I copied the books online code for creating a asymmetric key and then used this key for creating a login. Now when I try to login without entering any password I am receiving 18456 error. I would like to know what I am missing here. If I use CREATE LOGIN from asymmetric key or certificate how do I login and with what credentials. Do I need to provide any password.CREATE ASYMMETRIC KEY PacificSales09

An error message was shown on the status bar. It indicated that JavaScript Error: 'Return' statement outside of function. Seems something wrong with the 'Delete' funciton in SQL 2005 after update.

Hi, I'm new to SQL Express 2005.
I found information regarding : "Cannot open user default database. Login failed."on this forum but I think that in my case it's a bit different issue.
I have a website (ASP.NET 2.0) accessing DB, in the mean time Windows Service tries to update some data in the same DB (Service runs as NT AUTHORITYLOCAL SYSTEM). The second connection is rejected: "Cannot open user default database. Login failed.Login failed for user ....".
Problem occurs only when both: service and website are running at the same time. So service and website are running without problems when they are connecting DB exclusively.
My connection string is:
"Data Source=.SQLEXPRESS;AttachDbFilename="|DataDirectory|spider-lab.mdf";Integrated Security=True;User Instance=True"
I would be grateful if you can help me

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....
Thanks heaps

IIS has 4 websites hosted on it. The parent level allows anonymous with windows auth off, but the website level has anonymous off with widnows auth and digest.
In IIS, is there a problem with having the parent level anonymous and website level windows auth?

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>

Our server has integrated security setup, upon startup of the server,
we have a continuous flow of error msg:
Login Failed: Reason: User '_' not defined as a valid user of trusted
connection.
The timing of these messages only around 30 seconds apart
The only incident from Technet I can find is Q186314, but we don't have replication setup, anyone knows where I can look into ?
I recycle the server but didn't help.
I appreciate any help I can get ..
Thanks.

Code Snippet
Login failed for user 'KOQuotes'. The user is not associated with a trusted SQL Server connection.
