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 'NT AUTHORITYANONYMOUS LOGON'

Mar 21, 2005

Hello everyone,

I am receiving the above error when using a workstation to connect to my webfiles.

I am using windows authentication (whcih I have selected as my only option on the IIS).
Impersonate is set to true in the webconfig file, with authentication set to Windows.

My connection string is: SQLConnection1 = "initial catalog=SIMS;data source=spacesql;integrated security=SSPI"

It runs no problem when I use the localhost.
It allows me to use other aspx pages that do not connect to the SQL server.
It only gives me this error when I am using a page that tries to connect to the SQL server.

The SQL files reside on a separate server to the IIS and I would like it to remain this way.

Can anyone help me wit this please

Thank you,

Rebecca

Login Failed For User 'NT AUTHORITYANONYMOUS LOGON'

Mar 14, 2007

I get the following error message when I select a report:


An error has occurred during report processing.



Cannot create a connection to data source 'PSS5'.

Login failed for user 'NT AUTHORITYANONYMOUS LOGON'.

My Data source is set to Windows Integrated Security when I get this error message. If I change my data source to be "Credential supplied by the user running the report", the report generates fine. I am running SQL 2005 SP2. I have SQL reporting services installed on different server than my database services. Both servers are W2K3 R2 x64.

My IIS website and virtual directories are set up for Integrated Windows Authentication. My IIS application pool is set up to use an AD service account. I have followed the step/procedures outlined at: http://www.microsoft.com/technet/prodtechnol/windowsserver2003/technologies/security/tkerbdel.mspx

http://blogs.msdn.com/sql_protocols/archive/2005/10/12/479871.aspx
http://blogs.msdn.com/sql_protocols/archive/2006/08/10/694657.aspx

but to no avail. I am sure that I am missing something, but I can't figure out what. I would like to use Integrated Authentication, any ideas?

Login Failed For User 'NT AUTHORITYANONYMOUS LOGON'

Feb 27, 2007

Hello all -

I'm trying to connect to a Sql Server 2005 database from my local development machine, which is running IIS 5.1 (Windows XP Pro). The web application is not using impersonation and has anonymous access enabled. In my system's machine.config file, I've set the processModel section to look like:

<processModel userName="System" password="AutoGenerate" />

This has been working fine for us connecting to SQL Server 2000 databases (running on Windows 2003). When we connect, I access Sql 2000 databases under the context of "OurDomainMyMachineName$". However, we've recently installed Sql Server 2005 on a new Windows 2003 server & when I connect to that server, I receive the error:

System.Data.SqlClient.SqlException: Login failed for user 'NT AUTHORITYANONYMOUS LOGON'

when trying to call the SqlConnection.Open() method. Our connection string is very basic:

Data Source=sql-dev2; Initial Catalog=TestDatabase; Integrated Security=True; Application Name=PrototypeWebservice;

In the Sql Server logins, we've granted the computer account "OurDomainMyMachineName$" db_owner access to every database (in both Sql Server 2000 & 2005).

I am able to connect to the Sql Server 2005 databases if I change my section in machine.config to <processModel userName="OurDominamyPersonalAccount" password="myPersonalPwd"/>, or if I move the application to an IIS6 server & set the application pool identity to NETWORK SERVICE, but we'd like to continue accessing our Sql Server 2005 databases (from our development machines running IIS5.1) as we currently access our Sql Server 2000 databases; under the context of "OurDomainMyMachineName$".

Would anyone have any ideas why this would be happening or how to resolve? Thanks in advance.

Login Failed For User 'NT AUTHORITYANONYMOUS LOGON

Jul 6, 2007

Hello Guys,

I have two machines that i want to use for merge replication :


Laptop ( Publisher + Distributor )

VPS90 ( Subscriber )

Both connected via the internet

NO DOMAIN

Need to implement merge replication ,after initializing the snapshot I get the following error on both machines :


Login failed for user 'NT AUTHORITYANONYMOUS LOGON'. [CLIENT: 192.168.1.1]



I created a new user "Repuser" (admin)with the same password on both machines and configured the Agent proccess to run under that account ,now i get this error :
Login failed for user ''. The user is not associated with a trusted SQL Server connection. [CLIENT: 192.168.1.1]





Please note that :


· Mixed mode authentication IS ENABLED ON BOTH MACHINES
· BOTH MACHINES CAN PING AND ACCESS EACH OTHER ,BOTH COMPLEETELY VISIBLE.
· CONFIGURED ALIASES ON BOTH MACHINES.
· Both configured to use Sa account .
* I have NO DOMAIN


what does this mean?

It simply means that the SQL Server Agent process account is the one that€™s being authenticated to connect to the other machine and NOT the Sa account ,WHY?



do i have to use Web Synch in my case?

Login Failed For User 'NT AUTHORITYANONYMOUS LOGON' (but User.identity.name Is Correct)

May 1, 2007

I need help.  The security principal is the correct DomainUser, but the error message says I am not authenticated.
So here is my error Message:

Here is the Connection String:
Private ConnString As String = "Server=10.144.162.111;Database=DNS;Trusted_Connection=True"
 
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?

Login For User Sa Failed -- Not A Trusted Connection

Jun 24, 2007

I have 2 (XP Pro) machines -- each with its own instance of 2005 Express. I wrote a simple test in C# to access a few global vars such as @@VERSION.



When I run the test on 1 machine it works fine, but on the other machine it fails with the message: login failed for user sa, not a trusted connection. Both instances of Express have mixed mode authentication enabled & remote connections enabled.



If I add Integrated Security=true to the connection string, the test works on both machines. I believe this forces the connection to authenticate using Windows instead of SQL Server.



I have created a new user & password in Express, but the results are the same: 1 machine works & 1 fails.



The machine that fails is missing the following from the list of logins:

AIRSTREAMSQLServer2005MSFTEUser$AIRSTREAM$SQLEXPRESS



In fact, after poking around, I can see the problem with just the 2005 Management Console. Cannot access the 1 machine with SQL authentication using either of 2 users -- just in case I got 1 wrong.



Any help will be appreciated. I've run out of any good ideas.



TIA,

Joe

Login Failed, User Is Not Associated With A Trusted SQL Server Connection

Oct 24, 2006

I set up SQL Express and Visual Studio Team System for the first time yesterday. I created a web service (on my localhost IIS) and added an MDF file to my App_Data folder. I added a table with five fields. I'm trying to connect to the database in my web service, but when my web service gets to the connection line it returns the error

System.Data.SqlClient.SqlException: Login failed for user ''. The user is not associated with a trusted SQL Server connection.

When I add in my domain name and password to the connection string I get the error

System.Data.SqlClient.SqlException: Login failed for user 'redmonddanmor'. The user is not associated with a trusted SQL Server connection.

I've queried these SQL forums, and the advice is usually "add the user to the trusted users" or "changed to mixed mode authentication", but none of the posts I found specified HOW exactly to do either. When I launch SQL Server Connection Manager all I can appear to do is stop and start the service. I'm not sure what needs to be set for SQLEXPRESS properties to log on as Network Service, Local System, or Local Service.

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

Hello, here we have 2 developers, one developer has sql 2005 in his machine, the connection string has Integrated Security=SSPI, that developer can connect to the application, the other user gets that error when he tries to execute the application froms its own IIS.

The sql server has windows authentication, I want that the application uses one account, I tried to create one account, and give db_owner to it on the database, then I changed the connection string and it happens the same thing.

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.

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.

Login Failed For User David. Reason: Not Associated With A Trusted SQL Server Connection.

Jul 26, 2006

I am very new to SQL Server Express, so I watched the video on how to create permissions in SQLSE. I did what I seen, and I still cannot connect to the specifed database.

I did create a login account in the main part using SQL Auth., then I create a login account in the database, and set its role as dbowner.

After all that I disconnected the object explorer and tried to use the account that I just made and it didnt work, I also went to VBE and tried to connect from within the database explorer and I got the same error above.

I can go to a different pc and try to connect with the same result.

I did watch the video again to make sure that I didnt miss up and what I did was right by the video.

I did try to set another name and user account with no prevail.

Where did I miss up?

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

Ian

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.
