Error 18456 When Trying To Connect To 2005 Using Odbc

Oct 1, 2006

Hi all

I am using Windows XP SP2 with a Sql server 2005 Express installation. I created a test db with a user called test, schema also test. I gave the permission connect, db_datareader and db_datawriter. I can now connect into this user using WinSQL. But if I want to connect using a application which is using ODBC, then I get the error:

[SQLSTATE=28000 - [Microsoft][SQL Native][SQL Server]Login failed for user 'test'.[Native Error=18456]]

Because I connect using ODBC, I think there must be the problem. But I have to connect with ODBC. There is no other possibility.

any ideas ?

Regards, Waff

I found this out:

The server collation is defined to: Latin1_General_CI_AS

If I create a new login id in lowercase, then ODBC will change it to uppercase and then the server refuse the access. But why. CI means case insensitive, so doesn't matter if upper or lower case. should.

How do you use a id in lowercase and connecto via ODBC ?

SQL Server 2005 X64: Intermittent Error: 18456, Severity: 14, State: 10.

Jul 21, 2006

Hi,

We are experiencing intermittent authentication errors "Error: 18456, Severity: 14, State: 10" on a customer's production server. This is a new server that has just been rolled out in the past several months. Rebooting the server appears to make the problem go away. We are using SQL authentication from a separate server that is running IIS. The application always uses the same username and password to connect.

Server info:

select @@version

Sample error from SQL Server errorlog:

MSDN (http://msdn2.microsoft.com/en-us/library/ms366351.aspx) lists various states for this error message but 10 is not included, and it says "Other error states exist and signify an unexpected internal processing error."

Note: This was not a case of a transient error that occurs only when SQL Server is starting up - these errors occurred at a variety of times, two months after the server was last rebooted / SQL Server last restarted.

Thanks for any help you can provide.

Regards,

Connect To SqlServer 2005 With Odbc

Feb 28, 2008

Hi all,
I'm not a db guru and probably this is a very simple question for you, but I was wondering if it was possible to connect to a SqlServer using odbc without DSN.
I mean, I'm trying to connect to the db server from a linux (Fedora Core 8) workstation, using odbc drivers, but it looks like I can do that only using a DSN connection and setting properly the odbc.ini file. It doesn't work, if I use a connection like this from a PHP script:
$cn = odbc_connect("Driver={SQL Server};Server=MyServer;Database=MyDatabase",
"MyUser","MyPassword")
Does anyone know how to connect to SqlServer with a DSN-less connection? Could you explain me where is the error?

I'm using SQLServer2005, Fedora Core 8 with the last FreeTDS installed.

Please help!

Thanks million in advance.

Cannot Connect To SQL 2005 Using System DSN ODBC Connection

Dec 28, 2007



I am running SQL 2005 SP1 on Win 2003 Std x64 SP2. I get an error trying to connect using an ODBC System DSN connection. The ODBC connection gets the following error:


Connection failed:
SQLState:'28000'
SQL Server Error: 18456
[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'sa'

The SQL Server logs the following error:

18456, Severity: 14, State: 8.

I have tried this with several SQL accounts. I am able to login to the SQL Manager with the accounts without issue. It is only when trying to connect via ODBC that I get the error. I am currently downloading SQL 2005 SP2 to see if this will help with the issue. Any other ideas would be greatly appreciated.

Thanks.

Cannot Connect To SQL 2005 Using Vista ODBC Administrator

Mar 12, 2008

Here's the context:

Database server:
- Remote machine running SQL 2005 Standard as a named instance
- Named pipes and TCP are enabled for remote connections
- SQLBrowser service is running
- Listening on default named pipe (\servernamepipeMSSQL$instancenamesqlquery)

Client:
- Vista Business machine
- Not in same domain as server, but on the same network (via Cisco VPN)
- SQL 2005 Express is installed (for use with local databases)
- Windows Firewall enabled
- Running Symantec Antivirus, Corporate Edition

Connectivity:
- I CAN connect to SQL 2005 databases on the remote server using "nperverinstancename"
- I CAN connect to SQL 2005 databases on the remote server using Excel 2007

The problem is that I cannot successfully create an ODBC datasource using the "ODBC Data Source Administrator" application. I'm using the "SQL Server" driver and trying to create a System DSN. I'm also running the tool with elevated permissions.

- When I try to use "servernameinstancename" as the server and TCP as the connection type, I get this error:

Connection failed: SQL Server Error: 18452; "[Microsoft][ODBC SQL Server Driver][SQL Server] Login failed for user ''. The user is not associated with a trusted SQL Server connection.

- When I try to use "npervernameinstancename" as the server and Named Pipes, I get this error:

Connection failed: SQLState: '01000'; SQL Server Error: 1326; [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen(Connect()).
Connection failed: SQLState: '08000'; SQL Server Error: 17; [Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied.

Help! I've really been beating my head against the wall on this one. It all works just fine with a Windows XP client machine.

Runtime Connect Error To ODBC System DSN

Feb 24, 2006

Hello,

I have created an SSIS package to retrieve data from a Lotus Notes database using the NotesSQL 3.02g ODBC driver.

In SSIS design mode, I can connect to the Notes datasource using the following connection string without any validation errors.

uid=UserID;Dsn=LN_Costs;

I have tried other variations of the connection string including every possible connection string parameter available to the driver as follows.

server=Server_Name;uid=UserID;Dsn=DSN_Name;Driver={Lotus NotesSQL Driver (*.nsf)};database=costing/productcost.nsf;username=UserID;encryptpwd=encrypted_password;maxsubquery=20;maxstmtlen=4096;maxrels=20;maxvarcharlen=254;keeptempidx=1;maxlongvarcharlen=512;showimplicitflds=0;mapspecialchars=1;threadtimeout=60;

Using the above connection strings in SSIS design mode, the datasource test succeeds, and an sql select statement in a datasource reader returns the table structure with no error.

However, when I try to run the package, I receive the following error.

SSIS package "Sales Data Load.dtsx" starting.
Information: 0x4004300A at Data Flow Task, DTS.Pipeline: Validation phase is beginning.
Error: 0xC0047062 at Data Flow Task, DataReader Source 2 [408]: System.Data.Odbc.OdbcException: ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

Error: 0xC0024107 at Data Flow Task: There were errors during task validation.
SSIS package "Sales Data Load.dtsx" finished: Failure.

Furthermore, I have packages configured in SQL 2000 DTS to use the same system dsn without any errors.

Why doesn't this work in SQL 2005 SSIS?

Thanks.

Connect SQL Server 2005 With ODBC Drive “SQL Native Client

Sep 13, 2007



Hi,



When I'm using SQL server 2005, and ODBC drive €œSQL Native Client€? I get an error when executing the below given code. Error Message: €œTransaction cannot start because more than one ODBC connection is in use.€?



But this works well with SQL Server 2000 with ODBC drive "SQL Native Client" and in SQL server 2005 also when I used ODBC drive €œSQL Server€?.



I used aTrgConn.Execute(€œBegin Transaction€?) and it's working properly. But unfortunately I cannot use this method, because I want to run the same code with Oracle ODBC as well.
Is this a known issue in SQL Native client drive with SQL server 2005? Do you know a solution for this?


Please Help..............



Thanks in advance.




Code:

Dim aTrgConn As New ADODB.connection
Dim aCmdIns As New ADODB.Command
Dim aCmdUpd As New ADODB.Command



aTrgConn.Open sConnStr



Set aCmdIns.ActiveConnection = aTrgConn
Set aCmdUpd.ActiveConnection = aTrgConn

I am trying to connect to a remote SQL server via Management Studio. I am using the windows credentials I use to log into the computer but when I enter the same domainusername and password I get error 18456. I check the logs and see it is a state 6 error.

Setting Up Replication Gives Error 18456 - Please Help

Feb 29, 2000

I am using the Configure Publishing and Distribution Wizard in the SQL Server Enterprise Manager to configure a server as a Distribution and Publishing server. The security configuration on the server in question for authentication is SQL Server and Windows NT.

When I get to the first page in the wizard I select that I want to use the server as the Distributor. The other option is to use another server for the Distribution server - and this isn't what I want to do. The next page presents the option to use the default settings to configure the distribution databases or to configure the setup. If I select the default options I get the following error message when the arrow is pointing to Configuring Distributor:

----------------------------------------------
SQL Server Enterprise Manager could not configure 'SERVER1' as the Distributor for

'SERVER1'.

Error 18456: Login failed for user 'sa'.
Remote logins for remote server 'repl_distributor' have been dropped.
Server dropped.
Server added.
Server network name set.

----------------------------------------------


Something I have tried to change in order to fix this issue is the 'Replication agents on the Distributor log into the Publisher:' option from its default (By impersontating the SQL Agent account on 'SERVER1' (trusted connection)) to 'Using SQL Server Authentication of this account:', and in those fields I have put in 'sa' (which is a valid admin account to the SQL server) and the correct password.

In all cases I get the message above. Can anyone help me to see what I am doing wrong?

Thanks for your time,

Error: 18456, Severity: 14, State: 11.

Apr 4, 2008



This error has come up time and again and I can't seem to find a solution.

Specs: SQL Server 2005 v9.00.3054 on x64, Windows Server 2003 SP2

The user is a member of an active directory group. When he connects from his workstation via Management Stuidio, the error is:

Login failed for user '<domain><user>'. [CLIENT: xx.xx.xx.xxx]

I've dropped and re-created the login for the group, but to no avail. I've tried

SELECT * FROM sys.server_principals
and I get a valid entry

I've verified that the user is a db_owner in the database and that this database is the default for the group.

I also tried
SELECT endpnt.name,

suser_name(perms.grantee_principal_id) as grantee_principal,

perms.permission_name, perms.state_desc

FROM

sys.server_permissions perms,

sys.endpoints endpnt

Error: 18456 Severity: 14, State: 10

Jul 13, 2006

I have SQL 2005 Expess installed on Windows Server 2003 SP1.

My application is running as a service and is set to depend on SQL Server instance...
During the startup my app attempts to connect to the databes and it fails to do so,
after 30 retries (1second appart). SQL Server log has this error msg:
Error: 18456 "Severity: 14, State: 10"

Once the server has started, I cam manually start my application and it then sucesfully
opens a connection to the database.

What does this error mean?

SQL Server 18456 Error State 16

Mar 25, 2008

hello all

Since some days, i have this problem : i changed RTCcomponentService password, and now, when the SQL Server RTC service start (correctly, with network service), i have this log error message :
Login failed for user 'CGAUPARTCComponentService'. [CLIENT: <named pipe>]
ErrorReportingManager: Error raised, major=184, minor=56, severity=14, attempting to create sym

so, the service run with network (nt authority) correctly, but i have this error message.
I think that the sql server database connect with rtccomponentservice old password.
How I can change the password on this connection ? or what is de default password for RTCcomponentService ?

THanks

Error: 18456, Severity: 14, State: 16.

Dec 21, 2006

I am getting the error

Error: 18456, Severity: 14, State: 16.
Login failed for user 'PRIsqlservice'. [CLIENT: 172.16.9.2]

in the log repeated every 15 seconds or so. I am logged into the server as prisqlservice, I have started the sql server and sql server agent with prisqlservice and I can access databases and tables inside the Server Management studio. I have set up the login prisqlservice and given it dbo owner access to all databases.

I am in the process of upgrading from 2000 to 2005. I have installed a new sql server 2005, restored backups of databases from 2000. I have also converted all packages and uploaded those to the new server (although they all point to the 2000 server). I have imported the jobs, but all but one are disabled and the one that is enabled ran okay when I ran it manually.

I have researched and researched this issue, and none seem to apply to my specific issue.

This is an extract of my errorlog:
