SQL 2012 :: Login Successful But Still Generate Error 18456
Feb 2, 2015
I recently attempted to change the password of the sa login. There were no issues while updating the password neither did I get an error when I logged in as sa. Everything appeared to connect and I was able to query a database. However, an error was logged (error 18456 severity 14 state 8) as though I did not log in successfully. Even though I can connect successfully, I don't like having these misleading errors in the SQL Server Log.
I get this error when trying to connect. I'm using the sa id and password for all of my odbc connections. It fails when trying to connect to this one but it's ok on a couple of others I've set up with the same id etc. Where is this "" coming from and how to avoid it in the future?
I've removed and recreated the connection to be sure that I didn't actually type that in as the id....hey it's monday...it could happen.
Hi, I have just installed Windows Vista and SQL Server 2005. When I try to connect to my local server with Windows Authentication, I get the follwoing message:
Login failed for user <user> (Microsoft SQL Server, error: 18456)
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.
A user is trying to connect to a server via windows authentication from SQL management studio on her desktop.
The log file on the server gives: Login failed for user: domain1user1 Error : 18456, Severity: 14, State: 11
The strange thing is that the user in the error above is not the user she's trying to connect as (domain2user2, say). user2 can remote desktop to the server and log in there.
I know this state implies "Valid login but server access failure".
Has anyone run into this, and what more information would be useful to know? Thanks!
I just upgraded SQL Server 2000 to 2005 without any errors. Afterwards, I tried registering with sa and it failed. I registered with another sysadmin login to get into most of my databases, but I need sa to work for my backup software Idera SQLSafe to login to the database.
Does anyone have any experience or recommendations? I know my password is correct.
can someone help me with this error. Error: 18456, Severity: 14, State: 16 Login failed for user 'NT AUTHORITYSYSTEM' [CLIENT:<local machine>] I've found several Threads but not with the NT AUTHORITYSYSTEM.
Please help I keep getting this message when I log on to my data base. Not sure what state 1 relates too

hi, i am getting the following error message while i am trying to login to the SQL Server 2005 on my vista laptop. i installed the server with dual authentication modes.
Login failed for the user'xxxx'(Microsoft SQL Server 2005. Error:18456)
if you have solution for my problem please send a reply as early as possible.
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 21:45:10.64 Logon Error: 18456, Severity: 14, State: 11. 2006-08-13 21:45:10.64 Logon Login failed for user 'LAPTOPGuest'.

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

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
I am trying to create a linked server between 2 SQL Server 2005 boxes. When I create the linked server I specify a login for the connection. The strange part is that I get the following error when it goes to test the connection:
The test connection to the linked server failed Login failed for user 'Domainuser'. (Microsoft SQL Server, Error: 18456)
I can use the SQL mangement studio to conenct to the database using this same login. The login has all the server roles assigned to it also.
Can anyone shed some light as to what may be the problem?
I wanted to check the asymmetric key option in sql 2005. I copied the books online code for creating a asymmetric key and then used this key for creating a login. Now when I try to login without entering any password I am receiving 18456 error. I would like to know what I am missing here. If I use CREATE LOGIN from asymmetric key or certificate how do I login and with what credentials. Do I need to provide any password.CREATE ASYMMETRIC KEY PacificSales09 WITH ALGORITHM = RSA_2048 ENCRYPTION BY PASSWORD = 'bmsA$dk7i82bv55foajsd9764'; GO
CREATE LOGIN asm FROM ASYMMETRIC KEY PacificSales09;
I have a standard Login ASP.NET 2.0 control on a login Page, a LoginName and LoginStatus controls on the member's page. once the user login successfully I am redirecting the user to Member.aspx page. The following is my machine configuration
Windows XP Pro Service Pack2 IIS 5.1 SQL Server 2000 visual Studio 2005 DISABLE ANONMYOUS ACCESS IN IIS ENABLE WINDOWS AUTHENTICATION
I am Using form authentication, and I am getting following error "Your login attempt was not successful. Please try again".

I regularly (every month or so) get the error "The target principle name is incorrect. Cannot generate SSPI context" when trying to remotely connect to my SQL 2012 instance. The SQL service is running using a managed service account. I understand this error can occur when the service account cannot authenticate with AD properly. Looking at the properties of the managed service account, the password for the account was automatically changed this morning - just when the error started.
I am running several instances of SQL Server 2005 sp2 on a W2k3 sp2 box (member server).
This morning, I installed reporting services to one of my instances and shortly after noticed I was getting the following two messages in my SQL Server log file:-
08/08/2007 11:05:03,Logon,Unknown,Login failed for user 'DOMAINDOMCONTROLLER$'. [CLIENT: xxx.xxx.xxx.xxx] 08/08/2007 11:05:03,Logon,Unknown,Error: 18456, Severity: 14, State: 16.
The above entries were each repeated 6 times every 15 minutes but with State 11. I created a logon for the above, and now get the above messages (state 16) repeated 3 times every 15 minutes!
Last night I setup my MOSS 2007 server and SQL 2005, I got everything working fine in short order.
I had forgotten to look for updates for SQL 2005 so i decided I would run Windows Update.
SQL Server 2005 Critical Update for SQL Server 2005 Service Pack 2 (KB 934458)
Tuesday, March 04, 2008 Microsoft Update
SQL Server 2005 Microsoft SQL Server 2005 Service Pack 2 (KB 921896)
Those two updates were applied, then after a reboot I began getting the login failed error.
I can login using windows authentication as DOMAINAdministrator, I can also login as SA, but i am trying to figure out why it is denying me logins as DOMAINSharepoint
Has anybody had prior experience with this or know what the deal is?
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?
SQL2000 SP4 (SQL and Windows authentication) on Win2000SP4. Event ID 17055 (18456: Login failed for user 'sa'.) is being logged at an average of 20 times an hour. Tried to run SQL Profiler but it no trace information on the source (host, ip or application) of the failed login. Some forums suggest to unplug the server from network to know if its a local or networked issue but this is not possible in my case. Acquiring firewall/router logs from Network team is a headache. Any help on pinpointing what/where is this failed login coming from is very much appreciated.
We use AlwaysOn availability groups, which has 2 SQL nodes configured (version: 11.0.3373.0), my full and differential backups are working for all my databases, however I am unable to perform any LOG backups.
I have double checked my Availability Group settings, and the backup preferences is set to: 'Prefer Secondary'
I've tried creating a maintenance job as well as using Ola Hallengren's maintenancescript job to back them up, but nothing is written to the drive. All jobs return successful every time, and take less then 3 seconds to run. There are no events being written in the SQL error log or event log.
Our backups by default go to a network location, but I'd like to modify our maintenance plans to backup to an alternative location if the primary location isn't available. I've setup two Backup Database Tasks where the second one runs only if the first one Fails, and if the second one runs (on first one's failure) it then sends a notification to me so I know this occurred.
The Plan is running as expected, when I simulate a bad path in the first Backup Task the second one runs and the notification is sent, but the Job shows failure. I'd like to show the job as Successful when this occurs since I'm handling the issue and notification within the Plan, but I'm unable to find out how. I've set FailParentOnFailure to False on the Plan and I've changed the MaximumErrorCount to 2 with the assumption that this would work, but neither didn't.
Also I'm running into this in both SQL 2008 and SQL 2012.
I am setting up Availability Groups and I want to use the secondary replica to perform the full copy_only backups to reduce the load on the primary replica.But what is the best way to check for successful full backups on Availability Group databases?
Previously I could check the system table msdb.dbo.backupset but this is not available for copy_only backups.So I wonder how people are monitoring that their full backups have been successful?
Do you just check that the SQL Agent job that runs the backup was successful?
Or do you search the SQL Server Error Log for entries like "Database backed up. Database: xxx" where database xxx is in an Availability Group?
