Server Error In '/' Application - Login failed for user xyz ...

Hi, I'm brand new here
I would be ever grateful for help on this. It's probably something simple.
I'm coding a website in C# ASP.NET (http://project.arcza.net). There is a registration page where you send your email, username all that stuff to an SQL server. The SQL server runs on my IIS server too. On Visual Studio, I can debug the website (i.e. launch
it on localhost:12345) and I get a fully working website that I can register as a user and it injects into the SQL server's table. If I query the SQL server, I see the results. So it works fine here.
The problem: if I copy the files for the website into the live IIS directory (as opposed from the Visual Studio preview environment) I get a runtime error thing, I have no idea what this means. The live IIS folder is project.arcza.net and I have disabled
security so you can see the full workings of the probem.
It says login failed for user 'pap'. Pap is a user I have added in SQL server, with username pap and password pap. The credentials are correct. I have added a 'connection string' (I have very little idea what this is) with thees credentials for an SQL server
@ localhost, in IIS manager.
Thank you and if you have any idea I'd be very happy.
I should also point out that if I edit properties of pap in SQL server's login thing where it lists the accounts, I cannot save the settings (you know the ones where you give it permissions to access, delete, etc?) I can tick them and click okay but if I
reoped properties and click on (I think off the top of my head it's called 'securities' but I may be wrong, it's 2nd from the bottom of the pane on the left) I see the tickboxes remain unticked. Could this have something to do with the "login failed for
'pap'" message I'm seeing?

Have a look at
Errorlog. you should get reason of login failed for user.

Login failed for user 'xyz'. This session has been assigned a tracing ID of 'c2d....'. Provide this tracing ID to customer support when you need assistance.

Hello,
This error show up only when my application is running under Windows Azure. Everything work perfect on Windows Server 2008/IIS 7.5 with MS SQL server 2012.
What i try to do, is to change the database of the connection string at run-time.
My code use System.Data.Entity/ Entity Framework and the line of code i use is something like this using DbContext, IDbContext: this.Database.Connection.ChangeDatabase("dev_DB");
the error also say something like this:
[InvalidOperationException: This operation requires a connection to the 'master' database. Unable to create a connection to the 'master' database because the original database connection has been opened and credentials have been removed from the connection
string. Supply an unopened connection.]
I posted a ticket also to MS Azure support maybe they can do any settings to my Azure SQL version
Thank you.

When using SQLDatabase you cannot change an open connection string, you have to open a new one to the other database. Imagine that each database has it's own independent server. SQLDatabase is database has a service, not database server has a service.

Reports successfully execute but generate a login failed for user 'sa' err

I am running Crystal Reports Server XI R2. Classic ASP is used to generate embedded reports within our application. The crystal reports use ODBC to connect to a SQL Server 2005 database. The reports successfully generate in our Classic ASP application. However in SQL Server 2005, the following error messages are being generated each time a crystal report is ran:
- Login failed for user 'sa'.
- Error: 18456, Severity: 14, State: 8.
We know that we are passing the correct username/password to the crystal reports, becuase they execute successfully.
It appears that when the report is called, Crystal Reports appears to conect to SQL Server using a username/password that we didn't provide it at execution time, this fails and the SQL Server 'login failed for user' is generated. Then it runs the report using the username/password we provide and it successfully generates a report.
I have ran Profiler against the SQL Server Database and the 'Login failed for user 'sa' ' errors have a ApplicationName of either 'Seagate Crystal Reports' or 'Crystal Reports'. Therefore I know it is Crystal Reports generating these errors in SQL Server.
Does anyone have any ideas on how to stop these SQL Server 'Login failed for user 'sa' ' errors being generated?

What happens if you use Profiler when running the report using Crystal Report Designer?
If the report is ran through Crystal Report Designer, NO 'Login failed for user' error messages appear in profiler. Everything looks ok when ran in Designer.
Also, need to know what patch level you are on?
We are running Crystal Reports Server XI Release 2, Version: 11.5.8.8265
No additional patchs have been applied since Crystal Reports Server was installed.
We may try the SA account if one of the connections fail to log on with the credentials you provided. Verify the user you logged on with has rights to all tables.
The reports were running through our application using the SA account. The SA account has permissions to these tables. The reports do generate results and appear perfectly fine in the application. The issue is that when our application requests the report from Crystal Reports Server. Crystal Reports Server delivers the correct report to our application. However during the process to generate the report, 'login failed for user 'sa' ' errors are being generated in SQL Server 2005.
Also, I have tried creating a completely new SQL user called 'crystaluser'. I ran the report using Crystal Report Designer and used the crystaluser logon and saved the report. Then I ran the same report through our application. SQL Profiler will then display 'login failed for user 'crystaluser''.
Its seems as though Crystal Reports Server is first executing the report using the default SQL user saved with the report, but is either sending a blank password or no password at all. This generates the 'login failed for user' in SQL Server 2005. But it then uses the SQL username/password my application gives it and successfully generates the report. Of course this is only speculation.

BizTalk Powershell Provider Mount remote BizTalk drive: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'

I've been dabbling in the Powershell BizTalk Provider Extensions for some automation of deployment and such. So far it's pretty cool on a local machine, but the real benefits to me would be to do it remotely. Does anyone have any experience in the with the
following issue?
My BizTalk Server and SQL Servers are on separate machines which I think is the issue, but I don't know how to resolve. I've tried to provided credentials to the New-PSDrive command, but get the following errors:
The provider does not support the use of credentials. Perform the operation again without specifying credentials.
I'm trying to manage a remote BizTalk instance. The machine running the script has biztalk fully configured and can connect
to the Target Server just fine. The issue comes when I try to mount the "BizTalk:" drive
Enter-pssession -computername myServer -configurationname microsoft.powershell32
$InitializeDefaultBTSDrive = $false;
Remove-PSSnapin -Name BizTalkfactory.PowerShell.Extensions;
Add-PSSnapin -Name BizTalkfactory.PowerShell.Extensions;
New-PSDrive -Name BizTalk -PSProvider BizTalk -Root "BizTalk:\" -Instance mySqlServer -Database BizTalkMgmtDb -Scope Global
When it get to the New-PSDrive I get the following error:
New-PSDrive : Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.
+ CategoryInfo : InvalidArgument: (BizTalk:PSDriveInfo) [New-PSDrive], BtsException
+ FullyQualifiedErrorId : 0,Microsoft.PowerShell.Commands.NewPSDriveCommand
Has anyone experienced this and solved? The same error occurs when use Invoke-Command as well.

It seems that the PowerShell provider is not Microsoft Support, it is community supported through the CodePlex site -
http://psbiztalk.codeplex.com
Right, I posted there as well, but there is not much movement on the site. I was hoping to find if this larger community may have had some experience with the provider.

Cannot connect to SERVER. Login failed for user 'DOMAIN\user'. (Microsoft SQL Server, Error 18456) - SQL Server 2012 on Windows Server 2008 R2

I've seen multiple blogs and forums with similar problems and SQL 2012 or 2008. But no solutions that work for me.
I have installed SQL Server in mixed mode (SQL and Windows authentication). I can create new Login accounts in either mode. However, I cannot get an AD security group Login account to work. I am trying to add group 'DOMAIN\Domain Admins' or 'SERVER\Administrators'
as a Login so that any of the domain's administrator accounts can open SQL Server Management Studio and act as an 'sa' account on this server.
I have deleted the SQL account 'DOMAIN\Domain Admins'.
I have restarted SQL.
I have restarted the Win2K8r2 server.
I have launched SSMS as Administrator from the desktop of SERVER.
I have launched SSMS as another user (and used 'DOMAIN\user' to lauch it) from the desktop of SERVER.
I can create a login account named 'DOMAIN\user' (who happens to be a member of the 'DOMAIN\Domain Admins' group) and give this account 'sa' security, and when I do that, this account works as expected...
How do I add a security group as a Login account and give all members of that group the ability to be an 'sa' account?

Hi geoperkins,
Are you getting the following error message?
Error: 18456, Severity: 14, State: 11
Login failed for user <Domain\user>. Reason: Token-based server access validation failed with an infrastructure error.
If that is the case, the issue could be due to that the Windows login has no profile or that permissions could not be checked due to UAC. Please disable UAC firstly and check if it is successful to log in SQL Server.
Another reason could be that the domain controller could not be reached. You may need to resort to re-creating the login. Create a new group in AD, add users to the new group, then add the group to the local admin group and create login for the group in SQL
Server.
There is a connect item describing similar issue for your reference.

SQL Server Agent job between 2 instances fails with Error 18456 - Login Failed for user

Hi,
SQL Server version: 2012 EE
OS: Windows 2008 R2 Enterprise
In my server, i have 2 instances, and I am trying to configure a SQL Server Agent job to query one table in Instance A, and insert some modified data in Instance B, both in the same server.
When i execute the job in instance A, i get the following error:
Executed as user: NT SERVICE\SQLSERVERAGENT. Login Failed for user "NT SERVICE\SQLSERVERAGENT". [SQLSTATE 28000] (Error 18456). The step failed.
I have already configure instance A as Master and disabled encryption, by changing the parameter MsxEncryptChannelOptions to 0 in regedit. I've also made my target instance (instance B) as a Target.
What am i missing?
Thanks for your attention and pacience

Hello,
The NT SERVICE\SQLSERVERAGENT (virtual) account is not available on the other as you just mentioned. That is the reason for the login
failed error. Try using a Windows login as the
SQL Server Agent service account in both servers, the same Windows login (not a virtual account), and run jobs as the “sa” account.
http://msdn.microsoft.com/en-us/library/ms345578.aspx
You can also try a proxy account.

Non-SysAdmins get error 18456 Severity 14 State 11 Login Failed for user _ Reason Token-based server access validation failed with an infrastructure error.

I have a SQL 2008 R2 system (10.50.4000) where I'm having problems connecting any user that is not a SysAdmin. Example: I setup a new SQL Login to use Windows Authentication and grant that user db_datareader on the target database. The user attempts
to connect using Excel client or Access or SQL Management Studio and receives Error 18456. The SQL Server Logs shows Error 18456 Severity 14 State 11 Login Failed for user _ Reason Token-based server access validation failed with an infrastructure error.
The strange part is that if I temporarily grant the user the sysadmin server role then the user can connect successfully and retrieve data. But, if I take away that sysadmin server role then the user can no longer connect but again receives the Error
18456 Severity 14 State 11 Login Failed for user _ Reason Token-based server access validation failed with an infrastructure error.
We've turned off UAC on the client machine to see if that was the problem, but no change.
I have dropped and re-added the user's SQL Login (and the related database user login info). No success.
The Ring Buffers output shows:
The Calling API Name: LookupAccountSidInternal
API Name: LookupAccountSid
Error Code: 0x534
Thanks for any help.
-Walt

Yes, you understand correctly. The user is logging onto a workstation (not the server) with a Windows Authenticated id. The user is using either Excel or Access or SSMS and connecting to the server using a Windows Authenticated SQL Login account.
If the account has sysadmin role (which is only for testing) then the connection is successful. If I take away sysadmin role from the account then the connection is unsuccessful and the SQL Server Log shows Error
18456 Severity 14 State 11 Login Failed for user _ Reason Token-based server access validation failed with an infrastructure error.
(SQL Authentication is not an option here. I must use Windows Authentication).
Any other troubleshooting assistance you can offer would be appreciated. Thanks.

Receiving error message "Login failed for user 'NT AUTHORITY\SYSTEM'" every minute on server which is the mirror

Hello,
I have 2 SQL Server 2008 R2 machines that are configured with database mirroring (using certificates as authentication), there is no witness configured. My issue is that the mirror server is receiving at least one of the below pared messages every
second and filling up my sql error log quickly.
SYSTEM is the service account user for the MSSQLSERVER service.
[298] SQLServer Error: 4060, Cannot open database "<databasename>" requested by the login. The login failed. [SQLSTATE 42000]
[298] SQLServer Error: 18456, Login failed for user 'NT AUTHORITY\SYSTEM'. [SQLSTATE 28000]
The database has a status of: Affected database state is: Mirror, Synchronized/Restoring...
When I checking the database mirror monitor, it shows that its mirroring ok and everything has green checkboxes.
Is there a way to stop all these errors being logged, I'm assuming this isn't normal.
Marcus

Yes i have faced the same issues and tried everything and nothing was using this account, system was ended up with creating few GB's sql error log files everday.. and finally i had two options, 1 -- Rebuild the instance completely 2. Change the SQL Server
Audit settings to Only successful logins and restart the instance.. ( May be your current sql server level Audit setting is set to Failed & Successful logins..
Remeber my server was a DR so I have changed the SQL Server Audit settings to only Successful logins.. but production servers we will monitor both... :)

Unhandled Exception Error - Login Failed for User

Hello,
I am receiving an error when I run my application stating “Unhandled exception has occurred. If you click continue, the application will ignore the error………..Login failed for MyUser.
When I click the Continue button the application runs and seems to work properly. This application used to run without receiving the error and I did not make any changes. I have another application that is using basically the exact same code and does not
receive the error. The only difference is the application is querying a different DB but using the exact same connection string. The error only occurs when I run the exe file created from the build. When I run (debug) the application from within the VS 2013
IDE I do not receive the error.
Here are the details to the error message:

application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
I'm not sure what the JIT debugger is but to my knowledge my other apps are not using that. The production username and password are correct in the connection string so I'm not clear why I am receiving this error especially since I'm not receiving the
error on my other application. I have also attached the code just in case it is needed. Any assistance will be greatly appreciated. Thank you.

In SQL you have a login which allows access to the server but you must also have permissions to access each database that you will use (including Master). So I would verify that your user also has the necessary permissions on the database itself and
not just the SQL instance. The error you're getting is from SQL saying that the user doesn't have permissions. If it works for 1 DB but not the other on the same SQL instance then it is likely a missing permission on the DB itself.
I should note that you have a hard coded conn string in your code but the error is for a different user. I'm assuming that you simply posted it there for convenience and that you changed the values to obscure the data. If you are actually getting
the info from your config file then verify the connection string is correct. Also be sure to not use Integrated Security since it appears that you are using SQL authentication.

Error while invoking member: ManagedInit1 - Login failed for user 'SRCAdmin

I am trying to setup a Test Server for BOP 11.60 with MS SQL 2000 in MS Windows Server 2003. After installation, I copied user directory and database from live system to the new Test server. After installed the application andI updated Configuration Manager but when I run Planning Application Services, I have the following message:
System.Exception: Error while invoking member: ManagedInit1 - Login failed for user 'SRCAdmin'. ---> System.Runtime.InteropServices.COMException (0x80131904): Login failed for user 'SRCAdmin'.
   --- End of inner exception stack trace ---
   at SRC.Core.Common.LateBoundHelper.InvokeMethodDirect(String methodName, BindingFlags flags, Object[] args)
   at SRC.Core.Common.LateBoundHelper.InvokeMethod(String methodName, Object[] args)
   at SRC.Core.Host.HostProcess.StartUp()
I can use SRCAdmin user login to SQL Database without any problem but use Adminbop to start the Planning Application Services, I had this message.
Does anyone know what is the problem?
Regards,
Irene

Please, review your FBA configuration https://sharepoint2013fba.codeplex.com/

SQL Server Log: Login failed for user ''

We've found in SQL Server Log many records:

Message
Login failed for user ''. Reason: An attempt to login using SQL authentication failed. Server is configured for Windows authentication only. [CLIENT: <local machine>]
The server autentification is set to "SQL Server and Windows Autentification mode". But when we open SAP, before entering login/password, we see this message in log. But we still could work in SAP.
How could we solve this?
Kind regards,

Hi Joseph,
It doesn't help. The same things i've already done.
But when I change Mixed Autentification to Windows, i see another error:

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

"[DBNETLIB] Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection"
After patches applied on patch Tuesday the database reports the above error.
All accounts are domain accounts and SQLServer uses Windows auth.
DCDIAG show no errors
All servers and DC have been restarted,
Message in db log confirms the connection is being denied due to trust.
Event log shows same rejection
Protocols enabled: named pipes, tcpip, memory
TESTS:
PortQry: "
TCP port 1433 (ms-sql-s service): LISTENING"
Connect with domain admin accounts works from multiple clients systems to DB.
Cannot connect with newly created domain admin account
Can connect if new admin account connect to server in terminal server session and uses UDL wizard or any other tool including isql.
New standard user also fails to connect.
NOTES:
I removed the SSL patch and the IE security update to see if that was an issue.
¯\_(ツ)_/¯

Has someone left the company or has an account of some nature been dropped/replaced?

Hi Tony,
Srry but No. We just installed the monthly updates.
I went back and found I had missed removing a patch. I missed the rollup for Windows Server 2003:
Event Type: Information
Event Source: NtServicePack
Event Category: None
Event ID: 4382
Date:  3/12/2015
Time:  12:26:04 PM
User:  NETTEST\admin
Computer: DATA1
Description:
Windows Server 2003 KB954920 was removed from your computer, and the previous Windows Server 2003 configuration was restored.
After I removed that is still didn't work but after about five minutes it started working.
I guess I ned to report that to MS after I research what might be changed to make the patch work.
Every time I get stuck and ask for help it seems to be just before I stumble on the solution.
Thanks for replying.
Well - maybe this will help someone else.
Thanks again for replying Tony
¯\_(ツ)_/¯
