Error 15185: There Is No Remote User 'sa' Mapped To Local User '(null)' From The Remote Server 'DTS_FSERVER'.
Nov 10, 2006I am trying to add a linked server from a AMD x64 server (Windows 2003) with SQL Server 2005 64 bit to a Server running SQL 2000. These are not in the same domain.
I can create a linked server using the option "Be made using the login's current security context" but can not when trying to specify the security context, i.e. sa and the sa password. When I try I get the following message:
Msg 15185, Level 16, State 1, Procedure sp_addlinkedsrvlogin, Line 98
There is no remote user 'sa' mapped to local user '(null)' from the remote server 'DTS_FSERVER'.
I have several other x64 server that I have no problem creating a linked server and specifying sa and the sa password.
The problem with using "the login's current security context" option is that I get an error when trying to run any Jobs against the linked server. The job fails withe the following error:
Executed as user: NT AUTHORITYSYSTEM. Access to the remote server is denied because no login-mapping exists. [SQLSTATE 42000] (Error 7416). The step failed.
I'm sure the two errors are related. Any ideas what is going on?

Login Failed For User - Remote Database Connection
Mar 26, 2008Hi,
I have an ASP.Net web application running in groupnamewebservername. I am trying to connect it to the remote database server groupnamedatabaseservername using the ASPNET user id. The remote database is SQL Server 2005 and the web server has IIS 6.0 installed. My web.config connection entry has username as "groupnamewebservernameaspnet" and I have a database user in remote database server under the login name groupnamewebservername$. When I try to connect, I keep getting the following error:
System.Data.SqlClient.SqlException: Login failed for user 'groupnamewebservernameaspnet'.
Could you please let me know what I am doing wrong here? Thanks.
Regards,
Gayathri.

Feb 18, 2008All 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?

Remote Computer Not Able To Sign Into SQL Get Login Error
Jul 12, 2006I have 2 xp machines one has the SQL EXPRESS Server with all the goodies on it and the other I just install the client stuff. I am using VB 6 to program with using the ADO. It works great on the server machine. The software pulls up great. I can't seem to get it to work on the client machine. I get "Login failed for user 'TIGGERLGuest'. I found the places to set the TCPIP setings on the server SQL Express to allow this even turned on the browser but nothing same error. I am using the same login on both machines and am pointed to the same workgroup. I used window authentication when I set them up. Not sure why it insists on using Guest.
This is a copy of the connection string I am using

Not sure if this is okay for connecting remote. Any help would be greatly appreciated

Data Access :: Remote Data Object In VB5 To Get Current Login User?
Jul 13, 2015I'm using a legacy application built using VB5 and SQL Server 7. After recompiling it, and putting the database in SQL Server 2012. I want to access the current login user using the SQL function SUSER_SNAME().
This is the code.
Set rdoRes = goDatabase.Connection.OpenResultset("select suser_sname()")
But I'm unable to get the current user login in the application. If I write any other SQL statement instead of this, then it runs. But only this statement is not running. Is there any security reasons for this?

Login Failed For User '' ..... Sql Server, Error: 18452 (The User Is Not Associated With A Trusted SQL Server Connection)
Nov 7, 2007Hi
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]
Cannot Open Database Requested In Login 'dbName'. Login Fails. Login Failed For User 'machineNameASPNET'
Jul 27, 2005Been looking through the forums for a solution to this problem.I already tried granting access through statements such as:exec sp_grantloginaccess N1'machineNameASPNET'But they don't seem to work.. i vaguely remember seeing somewhere a DOS command line statement that grants access to the ASPNET_WP and that fixed my problem before on another computer.. but this is a new computer and i forgot to write down the command.Can anyone help explain and propose a solution to my problem. Many thanxs.

Error 7416 - Access To The Remote Server Is Denied Because No Login-mapping Exists
Oct 26, 2007I am trying to use a linked server and it works as long as I do not specify the sp_addlinkedserver @provstr parameter. If I specify that parameter I always get a 7416 "Access to the remote server is denied because no login-mapping exists" error. I have tried adding the logins various ways but it's very specific to the @provstr parameter, and it doesn't even matter what I put in that parameter. As soon as I put something in there whether it is valid or invalid, I get the error.
Anyone else seen this? There is an amazing lack of any discussion about the error when I search for it.
If I do this it works fine,
EXEC sp_addlinkedserver @server= 'linkedname', @srvproduct='', @provider='SQLNCLI', @datasrc='servername', @catalog='mydatabase'
EXEC sp_addlinkedsrvlogin 'linkedname', 'true', 'AppUser'
But as soon as I add the @provstr parameter, then I get the error if I try to use linkedserver,
EXEC sp_addlinkedserver @server= 'linkedname', @srvproduct='', @provider='SQLNCLI', @datasrc='servername', @catalog='mydatabase', @provstr='Failover Partner=otherservername'
EXEC sp_addlinkedsrvlogin @rmtsrvname='linkedname', @useself='true', @locallogin='AppUser'
It doesn't even make any difference what I put in the @provstr parameter - the sp_addlinkedserver statement always executes without an error, but running a query that uses the linked server generates the error.
Login Failed For User Error
Jun 23, 2004Hi
I have installed sql server on my standalone PC.
I used "window and sql mix authentication" for the sql server in the enterprise manager set up.
when I try to use the sql server login name for the startup service account, I have this error. "No Mapping between names and security IDs ".
So Even though I use mix authentication, I am still using window login name.
Then I create the DSN file.
But when I run the ASP program, I have this error "login fail for user-("user name that I used for dsn file configuration").
I try to configure the dsn file set up with both authentications, windows and sql login names.
But I got the error again.
I am really lost here.
Please help me. thanks...

Installation Error: Login Failed For User 'sa'.
Apr 4, 2007Hi everyone, I need some help.
I am trying to install a clean copy of SQL 2005 onto this server. It goes along fine until installing the "SQL Server Database Services" when I then get:
SQL Server Setup could not connect to the database service for server configuration. The error was: [Microsoft][SQL Native Client][SQL Server] Login failed for user 'sa'. Refer to server logs and setup logs for more information. For details on how to view setup logs, see "How to View Setup Log Files" in SQL Server Books Online.
There did used to be SQL installed on this server, but we un-installed it. What do I need to do now to install a fresh copy of SQL?
Thanks!

SqlException (0x80131904): Cannot Open User Default Database. Login Failed. Login Failed For User 'xxxASPNET'
Jun 17, 2007Hey 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.

Login Failed For User '(null)' Error When Opening A SQL Connection
Jan 16, 2005Hello everyone. I'm very new to asp.net. I've been coding in vb.net for a while now (getting my associates degree in desktop application programming) and my boss wants all of my new applications to be web based now. Well, i decided to take some initiative on this and begin a new project for my department. This is a very small project. So far, everything is coming along alright (i found an eBook that's helped me quite a bit). Everything was cool until yesterday when i tried to connect to our sql server database. I get an error message stating:

Because i'm testing this on my system as well as the remote system which hosts the application, i can see the error message on the remote system. Here is the error it's giving me:

Login Failed For User '(null)' Error When Trying To Use Windows Authentication
Feb 6, 2006I'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?
OLE DB Or ODBC Error: Login Failed For User 'NT AUTHORITYLOCAL SERVICE'
Apr 27, 2006Hi,
I need help with a problem: When trying to process a analysis services project, I receive the following error message -
OLE DB error: OLE DB or ODBC error: Login failed for user 'NT AUTHORITYLOCAL SERVICE'.; 28000; Cannot open database "DocumentDB" requested by the login. The login failed.; 42000.
I am using the service account for impersonation for the datasource. One suggestion I received from the data-access forum was to grant privileges to the local service for the database. I am not clear about the procedure to do that. Can someone please guide me through this? I am posting this question in this forum since this is a authentication/privilege issue.

Stuck With Login Failed For User XxxxASPNET Error, Need A Hint Please
Jul 11, 2006Hi,
I am stuck with that error when running my ASP.NET application on my production server for many weeks now and still don't have a complete solution to that problem.
I formerly posted that thread and read that other thread without success, so as I have made a few progress in delimiting the problem I am posting this new thread with the hope somebody will finally be able to help me.
To summarize:
1) I have developed an ASP.NET application,
- on a Windows XP Pro SP2 computer
- with VS studio 2005 Dev and included SQL 2005 engine
- this application works fine on the dev computer
2) I have deployed the application on a production server which is:
- a Windows 2000 SP 4 computer
- with SQL Express SP1 with Advance services installed
When I launch the prod application I have this error:
Login failed for user xxxxASPNET
I have found that I can bypass this error by doing the following:
1) manually attach my .mdf database with SQL Server Management Studio Express and specifying the field Attached as with myDatabaseName (in place of the default fullPhysicalPath/myDatabaseName.MDF) then detach it
2) change the auto generated connection string in web.config file from
<add name="ConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|myDatabaseName.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
To
<add name="ConnectionString" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|myDatabaseName.mdf;User ID=sa;Password=mySAPassword;database=myDatabaseName" providerName="System.Data.SqlClient"/>
That would have been an acceptable substitution solution but unfortunately my
application also uses the new Login and Webparts features of VS 2005 which implies the automatic creation of an ASPNETDB.MDF database by VS.
As I have no mean (or at least don't know how) of modifying the associated Connection String for that database (it does not appear in web.config) I cannot bypass the problem for it and thus the error still appears when the application try to use this database.
Please I really need help on this matter, I can provide any other useful information as needed (logs, sources ...)
Error : Cannot Open User Default Database. Login Failed.
Aug 14, 2006
I work with Microsoft visual studio 2005.
i get data from a table by ADO.NET :
SqlConnection sqlConn = new SqlConnection(strConnectionString);
sqlConn.Open();
.....
it works fine.
but when i open the SQL Server 2005 express edition and connect to the server (inside the same computer) to check something and then get back to the VS and run the code again ,the Open() function fails with the exception :
{"Cannot open user default database. Login failed.
Login failed for user 'DOMAIN\asaf_a'."
disconnecting the server doesn't help and even closing the SQL Server 2005 application doesn't help.
Only restarting the computer enables the Open() command to work again.
Why ?
Error: 18456, Severity: 14, State: 16. Login Failed For User
Feb 22, 2007Hello.
I get this error when I try to connect to my SQL Server with JDBC:
Excepcion en MyPool Pool.getNewConnection() [Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]Cannot open database "lituania" requested by the login. The login failed.
And in the ERRORLOG I get:
2002-02-22 19:59:46.62 Logon Error: 18456, Severity: 14, State: 16.
2002-02-22 19:59:46.62 Logon Login failed for user 'frontend'. [CLIENT: 10.0.0.75]
I found it is supossed to be a password mismatch:

but I checked the password is correct.
Any ideas? Thank you in advance.
