I have a stored procedure that retrieves data via a linked server that is running on a local instance of SQL Express 2005. This has been working without problems for some time.
We are now trying to move the database with the links to either SQL Express 2005 running on a server, or an instance of SQL Server 2005. In both cases I can successfully link the servers but when the stored procedure executes it fails on the select statement from the linked server with the following message:
OLE DB provider "SQLNCLI" for linked server "mosier" returned message "Communication link failure".
Msg 10054, Level 16, State 1, Line 0
TCP Provider: An existing connection was forcibly closed by the remote host.
Msg 18452, Level 14, State 1, Line 0
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
Why is the user name null? I've tried explicitly setting login information by running the sp_addlinkedsrvlogin procedure but get the same results. In all cases logins should be using windows authentication and all the servers are inside the corporate firewalls.
I presume there is some property somewhere that is different between the SQL instances that work and the ones that don't but I haven't been able to find anything.
HelloI have just completed the first part of my first intranet project, using MS Access. Next step is to transfer it to SQL Server 2000 on a Windows 2003 Server.The ASP.NET code resides on an XP workstation.I get this error: "Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.".The connection string:Dim DbConn As New SQLConnection("Server=RDDSRV1; DataBase=Serialnrs; Integrated Security=SSPI").I have also tried the same string, with user id and password for a domain adminstrator. No difference.The database has Windows security with among others ASPNET as user (login?)I have searched throu the my own litterature and this Forum, but can´t find any answer to my problems.Hope I can get a quick anwer.Rolf Dahlström
I am using and learning Visual Basic 2005 Express edtion I have created a project and wriiten/adapted code, as below, to connect to sql server 2005 express edition, that works well.
Dim ConnectionString As String = "Integrated Security=SSPI;" + "Initial Catalog=JIMDbase2;" + "Data Source=.SQLEXPRESS;"
conn = New SqlConnection(ConnectionString)
' Open the connection If conn.State <> ConnectionState.Open Then Try conn.Open() Catch ae As SqlException MsgBox(ae.Message.ToString()) End Try
End If =============================================================
Later and in the same Project, via Database explorer I 'Add connection' to the same sql database to review tables etc. After this when I run the same code, as above, I get an error that the database is in use
If I then 'Close Connection' or even Delete the connection via Database explorer I receive the error
"Cannot open Database, "JimDbase2" requested by the login. The login failed. Login failed for User "..".
I'm trying to connect to another slq server db through a linked server (and synonyms) but I get the following error.
Exception has been thrown by the target of an invocation. ---> System.Data.SqlClient.SqlException: The current transaction cannot be committed and cannot support operations that write to the log file. Roll back the transaction. ,Unable to start a nested transaction for OLE DB provider "SQLNCLI" for linked server "BURT". A nested transaction was required because the XACT_ABORT option was set to OFF. , at Westfalia.TDMN.TxObjects.TxBurtOCIInterface.BurtOCIPalletChangedRecords_Get() , --- End of inner exception stack
I've set up MSDTC and executed the procedures noted in MS's article ID 873160. I am using 2005, but the Burt server is 2000. I can run the stored procedure from my server, which queries theirs. But when I execute the sp from a service, I get the error. Any help would be greatly appreciated.
We used Named Pipes network library when running SQL Server 2000. The firewall and ip address on the box were changed and reconfigured. We rebooted the server. We cannot start the SQL Server now.
I am using an unattended install script to install the database on the client machine. All the settings look correct. But my application cannot access the db -
Error: Cannot open database requested by the login.
Now when I install SQL Server Express manually, it works fine. I have the service running under local system and enabled user instances is true. I cannot figure out the problem(been working on it for 2 days).
We have see login failures for windows accounts. Below is the error message.
Description: In our env most logins are windows accounts. Initially we thought it is an UAC issue and we tried to launch the SSMS using "Run as Administrator". However, we are seeing login failures.
Enviroment: Microsoft SQL Server 2014 - 12.0.2402.0 (X64) RTM Enterprise Edition (HyperVisor)
Error Message in Error Log :

We tried dropping this account and re-creating the windows account with same permissions but still result is same. It throws same error message. Login failure message !!!
My application uses "crystal reports" control to integrate some reports that can be viewed from within the application.
I'm getting a login failed (due to bad password SQL State 8) error when I bring up the report from within the application. The report runs fine outside the application with the same username password.
- I've checked several times to make sure that I'm passing the correct username/password from the application. - All letters in the password are lower case. There is not case-sensitive issue. - I printed the username and password on a pop-up to see what values are passed , and they are correct. - A single test page that uses the same version of "Crystal Reports" control , using the same username/password, brings up the same report works fine.
I guess , my question is:
Is there a way to trace the login failure event on the SQL Server side to see what is the value of the password that is being sent by crystal reports control?
I'm using Crystal Reports XI with sp2. SQL Server 2005.
When we connect using a SQL login as specified in the above line we are able to connect to the linked server.
But when we want to connect using a Windows user it is connecting.(we want to connect using a specific windows user i.e only one windows user will be there in the server and we shall access the server using that windows user)
Is there any other way to connect to the linked serrver.. we dont want to use the SQL server login to connect to the linked server.. how to use windows authentication to connect to the linked server. Anyone have tried it out.. Thanks in advance
I then try to run the same app from the client computer, it gives me:
Login failed for user 'LAPTOPGuest'.
After looking up the web for solution, I found that I can test the connection from the HOST computer in this way:
C:Documents and Settingskit>sqlcmd -E -S laptopsqlexpress 1> 2>
The test is successful
Now I run the same command on the CLIENT computer
C:Documents and SettingsKit>sqlcmd -E -S laptopsqlexpress Msg 18456, Level 14, State 1, Server LAPTOPSQLEXPRESS, Line 1 Login failed for user 'LAPTOPGuest'.
Now I can sure that from the client computer it cannot make a connection to it, then I look at the errorLog from my host computer
2006-08-13 21:41:00.34 Logon Error: 18456, Severity: 14, State: 11. 2006-08-13 21:41:00.34 Logon Login failed for user 'LAPTOPGuest'.

Valid login but server access failure
It tells the connection string and SQL Express seem to be set up properly but the server access failed the remote connection
I have previously had SQL Server 2000 installed. I uninstalled SQL 2000 before I install SQL express but somehow the SQL Server Service Manager is still running at startup, and C:Program FilesMicrosoft SQL Server80 and its files are still exist after uninstallation..... Could this be a problem?
The Knowledge base suggestion on "enabling remote connection" is very simple and I do not understand why it is so difficult to me just to make a remote connection test work..... please, I need your help.
Recently, one of my clients began receiving this error. My team gave them sysadmin permissions, but this is terrible practice. I have read into disablying simple file sharing, but I don't even think I have the option to do it. I look in mycomputer > tools > view and don't see any option for this. Besides, the problem just started occuring recently, within the last week. The server is a cluster with veritas clustering and the edition is sql server 2000. Has anybody ever had a problem like this and have a good fix? Thanks for any help in advance... -Kyle
Can we assign two logins for two different databases on target server. For example, I would like to create a Linked Server between ServerA and ServerB.
ServerB has two databases on it and both using different logins to access. Say DB1 has Login1 and DB2 has Login2
I use linked serve with (Security :be made with specific security conterxt) to connect to my production server from a Data Archive server.
Stored Procedures loop throught the prodcution data to insert records into Archive tables...Howerver after few hundreds of iteration I get the following error...
"Access to the remote server is denied because no login-mapping exists."
I am confused with the error message as it happens only after some successful insertions....
Hi Folks SQL2k on NT4 Domain I have a UserDB on SvrA - Access to UserDB is Via a DomainGroup and is assigned db_owner role UserDB Executes a local SP which in turn Executes a remote SP on SvrB via a Linked Server The Linked Server Login Security is via mapping to a remote account which has db_owner on the remote DB. I would like to. a) stop ALL users on SvrA from being able to use this linked serverb) tightly restrict permissions of the remote account to the remote db Is it possible to MAP above local server login to remote server login as the local login is via a domain group. I cannot significantly alter UserDB current Login Security I'm also worried that another system/db is utilizing this Link (legally) but I'm not allowed on the production box to monitor it (Hhrummphh - but unfortunately I have the job of providing scripts to tighten security :rolleyes: - hence the prefference for mapping local to remote users I'm sorry I'm not well versed in SQL Security & this is only a central part of my bigger security job(involving horrible RPC's, dynamic SQL, heteregeounous joins, double hops, delegation etc) Any help appreciated GW
We are having some commercial applications that are running on sql servers at different sites, all with sql security. The software vendor wants to copy data into staging tables on our BI server. But our BI server only support Integrated security.
But how can i say, in the definition of a linked server (at the remote machines) to swicth security system ?
If it is possible i could enter a fixed domain-account in that users fields, but i suppose that this field was intended for SqlServer security.
I have created a linked server that connects a SQL 2000 database to a SQL 2005 database. If I use individual SQL or Windows accounts as local logins on the SQL 2000 instance, I can successfully query the linked SQL 2005 database. (For security we use the setting "For a login not defined in the list above, connections will: not be made")
If I try to use a Windows group as the local login, remote queries fail with the error "Access to the remote server is denied because no login-mapping exists"
Is it not possible to use a Windows group for the local login of a linked server?
If I run 'exec sp_linkedservers' the setup appears valid

My application is dependent on two databases one is on sql 2005 machine and other is on sql 2000 machine. A linked server is establish between these two using sql account which has appropriate rights on both server's databases.
application works fine but after some time it crashes and if i see error from sql profiler i get the error
OLE DB provider "SQLNCLI" for linked server "sql2000machine" returned message "Login timeout expired".
Few days back applciation was working absolutly fine, but i was trying to make linked sever through windows account, i dnt know wat has i changed during achiveing that setup that now application (linked server) is not working even with sql account.

I am planning to delete a login from SQL logins because he moved out from project .when i try to delete the login , it throws an error saying " The server principal owns an endpoint and cannot be dropped , error 15141 "
Same problem facing on different servers.
Note : Environment is SQL 2012,SQL 2008 including cluster servers .
I get this error when trying to alter a stored procedure that has an insert statement referencing a new linked server I created:
INSERT INTO [servername].databasename.dbo.DirectReport ...
Msg 18456, Level 14, State 1, Procedure Get_Direct_Pay_Move_Data, Line 17 Login failed for user 'NT AUTHORITYANONYMOUS LOGON'.
I added Administrators and my logon to the permissions of my linked server but still get this error when it tries to save my stored proc...the one which has that insert.
I am new to asp.net 2.0, although I have some experience with asp.net 1.1. In my new machine I have VS 2005, SQL Server 2000 and Sql Server 2005 installed. I wanted to connect to a database in SqlServer 2000 from a simple asp.net 2.0 project. I used the following connection string: string strConn = "Data Source=xyz/abc;Initial Catalog=dbname;UID=abc;PWD=efg;"; xyz/abc is the name displyed in the enterprise manager, under SQLServer Group. When I run the app, I am getting the following error: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) The error indicates that it is trying to connect to SQL Server 2005, although my xyz/abc is a SqlServer 2000 instance. Not sure how to force the connection to the SqlServer 2000 database. Thanks
Hello Everyone and thanks for your help in advance. I have set up a new installation of SQL Server 2005 and VS 2005. I am trying to get some web applications up and working, but am experiencing problems with the database connection. I am tring to use the the sa account to connect, but am receiving the error "Login for user 'sa' failed. Not associated with at trusted account...". I am familiar with this error and have made sure that the SQL Server is using SQL Server and Windows Authentication Mode. The connection string I am passing to it is: server=(local);uid=sa;pwd=password;database=Northwind which I believe is correct. So I'm confused as to what the problem is. Any help on this topic would be greatly appreciated. Thanks.
I am running sql server 7, since friday my users are not unable to access their database on the server. NT group authentication is the mode of accessing the data on the server, the temporary soluton I have found so far is to create individual login. Which means creating login for every user on the network. NT4 Group membership that has always worked no longer functions.
Hi experts, my server was having windows as well as sql login authentication. Once i checked the deny access for BUILTAdministrators . . I'am unable to login as SA and also I'am also unable to change that check as well. . .any solutions in this regard will be appreciated
Hello , this is my first posting in this group.I am running SQL server 2000 on my windows 2000 server box. I use itfor my Siebel database.When ever I launch Query Analyzer and chose SQL Server AuthenticationI get the error message below:[Microsoft][ODBC SQL Server driver][SQL Server]Login failure "SA" Not associated with a trusted SQL serverconnection.The funny thing is that if I use Windows Authentication the loginworks.I checked Enterprise Manager and the SA account is present.Any help appreciated .SQL newbieThanks.
There have been other similar posts, but this is my issue: I have set up database mirroring with a witness, and failover works properly. I have also installed the login id's and their original SID's onto the mirror server. When I run a Reporting Services report against the primary database, it runs properly. When I failover to the mirror server and run the report again, I get a "login failed for user" error. As I have already said, the SQL login that the Reporting Services report uses was installed on the mirror server with the original SID. Any ideas as to what else might be wrong?
I have the default instance of sql server (2005 express) installed on my machine. I can log on with no problems using the windows authentication but I had to create a new login account with a username and password.
I have added the new user using the Management Studio under the Security>Logins folder. I have assigned this new user has a server role of sysadmin and I have mapped the user as the db_owner of each current database on the server (default system db's). When I try to connect to this server (keeping in mind it works fine with the windows account) using sql server Authentication and the new username and password, I get an error that says "Login failed for user 'WblsUser'. The user is not associated with a trusted SQL Server connection. (.Net SqlClient Data Provider)"
There seem to be lots of posts regarding this issue but I was surprised that it should happen when you use the management studio as apposed to a connection string in an application (where the connection string could be typed incorrectly).
I have checked that the protocols for TCP/IP, Named Pipes and Shared Memory are all enabled for both the server and the client.
I would like a guest to view some items on the application.
And I recently intalled SQL Server 2000 on my machine. Will integrate Access when ready.
I can access or simply read data from a db if I specify User ID and Password.
Such as....
Dim nwindConn As SqlConnection = New SqlConnection("Data Source=localhost;User Id=sa;Password=xxxxx;Initial Catalog=Northwind;")
Yes, testing first, then adjusting all my code for the SQL instead of Access.
If I leave the id and pw out, it won't read - login failure. I have read so much on authentication and some posts here, even the one on login failure, but that didn't help.
Keep in mind, just installed, only users are the default ones by the installation.
What setting in the SQL Server is there, and I have looked, that if it's a guest, no id or pw, allow read only to items such as datagrids which only read from tables?
1. I Dump my Database into a dump device 2. I Rebuild my mater Database 3. I Restore my User Database. 4. At the end of the above exercise I find my relationship between sysusers (User Database) and syslogins (master) is totally screwed up. This has been causing logon problems to my User Database… 5. I tried using sp_change_users_login …but it does not seem to work.
I have several dts packages that run just fine through a third party scheduler. I then put a mail task on them to tell me if the package succeeded or failed. Every time the scheduler gets to the mail task it fails and logs a mapi login failure error. When I execute the dts package on my local box it sends the email with no problems. is it a problem with the robot login or is it associated to the profile? any help would be greatly appreciated.
