Login Failure

Jul 1, 2006

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

Login Failure

Aug 11, 2006

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.

Login Failure

Mar 18, 2002

Hi

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.

Please help.

Login Failure

Jan 16, 2007

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?

Login Failure

Nov 17, 2006

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.

Anyone got any ideas?

Login Failure For Guest

May 11, 2004

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?

Thanks all,

Zath

Dts And Mapi Login Failure

Jan 8, 2002

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.

Application Login Failure After SQL 6.5 To 6.5 Migration

Jan 16, 2001

Over the weekend, I attempted to move six databases from an older server to a newer one. I have installed SQL 6.5 on both with identical configurations. After migrating the data, bringing down the old server, renaming the new server and configuring the ip address, I ran into a problem. Two applications that access databases on the server were unable to login using any id other than the system administrator id. Each of these applications have been tested on a test server with the same configuration as the new and old production servers. Each installation is on an NT server with SP6 and each SQL install is using SP4. One of the applications gives an OLE DB error. Any suggestions would be appreciated. Thanks in advance.

Login Failure On A Linked Server

Jan 31, 2008

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.

Login Failure For OLE DB Data Connection

Aug 13, 2007

Hello,

I have encountered a problem with my data source connection. I have a data souce that uses a SQL Login to access a remote server. When I test the connection in the Data Source Designer all works fine. Even when I add the data source as a new data connection in my SSIS package an use it in a OLE DB Source component it works fine, in the preview window.

But when I try to run the package in debug mode i get the following error message,

I have a 2000 / 2005 side-by-side installation on our test server.

To login to 2005 with SSMS, the connect string is

There's a WiFi network connecting my client PC to the network.

SSMS fails to login frequently. I need to exit SSMS, then login again. It'll work.

A new problem today - after successful login, I can't open a project and login successfully. Error messages states "Failed to Login".

Any tips?

Maintenance Plan Fails Due To Login Failure

Nov 14, 2007



W2k3SP2 running SQL2k5SP2 in mixed mode. Trying to run a daily maintenance plan with a domain admin service account [domainsqlsvc]. This account is having login failure when I try to run the maintenance job. Would like to figure out why this account cannot authenticate with SQL. I believe I have local login denied, but login as a svc and login as a batch job are both enabled in Domain Policy.

What am I missing?

Login Failure - May Have Resulted From A Corrupted Restore

Jan 28, 2007

Hallo

I have a bit of a problem I haven't come across before. I was testing some restore code using smo, when the restore process got corrupted. Now I cannot log into that database file. Whenever I try and connect to it, I get a login error. Connections to this database file previoulsy worked very well.

I do not get login errors for databases with different names, or when using the same database file on another computer. There must be some data stored somewhere that is causing this. I have removed the database file and reloaded it, but to no avail. Any insight into this would be appreciated

Strange: Continuous Login Failure Errors

Jun 5, 2007

I have SQL 2000 Server that had a database called ABC and it has been moved to another server on 5-15-2007
I kept ABC database in Read_only mode for few days (just in case) on old server and finally dropped it on 5-20-2007 and I think I forgot to drop the associated logins. I started seeing login failure for user 'xyz' in error logs
When I first noticed the login failure error in SQL Server log for login xyz, I deleted xyz login but it did not stop the errors.

I have been trying from then and no luck in identifying the cause/ resolving this issue.
I have ran SQL profiler trace and caught the user hostnames, NTusername in few cases and Application Name and contacted the Application owner & user (who are in the trace) to stop windows service/ schedule jobs..anything that is pointing to old server but the bad luck is they are not aware of anything running or pointing to old server. The worst part is the user whose hostnames are shown in the trace have never used ABC database and do not have any idea.

Here is what I found in the profiler trace:
TextData LoginName NTUserName HostName ApplicationName
Login failed for user 'xyz' xyz AB00007 WAB000007 Microsoft (r) Windows Script Host

Today I have created the xyz login in the server and assigned model database with reader permission to see if log some different error but nothing new (the same login failure error)
Finally, I had no solution other than restoring the ABC database back to my old server and set it in to Read_Only mode to stop these errors and Now I see the login 'xyz' firing the query against the database

* Any hint or pointers why this is happening and any possible solution on this?

Setting Up DotNetNuke Am Getting 18456 Login Failure

Feb 20, 2006

I am running Windows server 2003, IIS 6.0, and SQL Server 2005. I am trying to set up dotnetnuke to run on the same machine as both these servers and I am running into an error that the dotnetnuke forum has not been able to help me with. I have set up a user called dnnuser in my windows authentication domain, and have added the user to SQL and given them ownershhip of my new dotnetnuke database. Howeever, when I try to start up DotNetNuke in my browser on the local machine I get a failure to log in. The first messages in theSQL Server log is "Error: 18456, Severity: 14, State: 6" then I get "Login failed for user 'DSD-WINdnnuser'. [CLIENT: <local machine>]" Then the next two lines in the log are "Login succeeded for user 'DSD-WINdnnuser'. Connection: trusted. [CLIENT: <local machine>]" and then "Login succeeded for user 'NT AUTHORITYNETWORK SERVICE'. Connection: trusted. [CLIENT: <local machine>]".
What would cause the server to reject the login once and then immediately accept it?

Any ideas would be appreciated!

Thanks,

Deb

SQL 6.5 Replication Task Failing Due To ODBC Login Failure

Nov 2, 1999

I'm "trying" to set up Replication. The Publishing/Distribution server is in one domain, and the subscribing server is in another. Both domains are fully trusted.

The synchronization step builds the .tmp file, but the repl_subscriber Distribution task bites the dust with an error message, "28000[Microsoft][ODBC SQL Server Driver][SQL Server] Login failed".

The setting on the distribution options dialog box is ODBC, SQL Server. I'm not using a special login/password. I've even tried putting a user name and password there, and it doesn't work. The ODBC connections test out fine on both servers. Any suggestions where I've gone wrong?

Thanks,

Login Failure Issue With Crystal Reports Connecting To SQL Server 2005

Nov 6, 2007

Hi All,


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.

I appreciate the help.

Thanks,
Satish

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'. [CLIENT: 192.168.0.5]

2006-08-13 21:48:41.80 Logon       Login failed for user 'LAPTOPGuest'. [CLIENT: 192.168.0.5]

Now I know it is actually  Error: 18456, Severity: 14, State: 11.

11 and 12

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.
