EVENT ID 18456 STATE: 16 Login Failed For User 'DOMAIN/user'. [CLIENT: &&<local Machine&&>] Every Minute In Event Log.
Oct 22, 2007
We recently upgraded to SQL 2005 from SQL 2000. We have most of our issues ironed out however about every 1 minute there is a message in the Application Event log and the SQL log that states:
EVENT ID 18456 Login Failed for the users DOMAIN/ACCOUNT [CLIENT: <local machine>]
This is a state 16 message which I thought meant that the account does not have access to the default database. The account is actually the account that the SQL services run under.
Any ideas? We can't seem to figure this one out. We actually upgraded to 2005 from 2000 and had an error appear after every reboot that prevented the SQL Agent from running(This application has failed to start because GAPI32.dll was not found. Re-installing the application may fix this problem.) We did a full uninstall of SQL and reinstalled fresh and restored the databases from .bak files and that is when the EVENT ID 18546 started occuring every minute.
We don't have any SQL heavy hitters here so please be detailed with any possible solutions. That you very much for any help you can provide!

One of my co-worker changed the sa password today. After that we are getting this error. The SA account gets locked every time. Even within few seconds of unlocking the SA account, it gets locked again. Error message is not clear as what session still using old password and causing the SA account to get locked? Any of our application does not use SA user to connect to databases. We have Tivoli installed on the same system and the GUI of tivoli has the correct password.

I just did a fresh install of SQL Server 2005 Developer Edition and SP1. I elected Windows auth during install. After rebooting I get 2 errors in my Application Event Log: MSSQLSERVER Login failed for user 'COMPUTERuser'. [CLIENT: <local machine>] (event ID 18456) and Report Server Windows Service (MSSQLSERVER) (event 107) which says: Report Server Windows Service (MSSQLSERVER) cannot connect to the report server database. In the data section it says it can't connect to the machines "master" database. I can manually login. How can I fix the problem and get rid of these messages? Thanks. Mark

Maintenance plan for bakcup is failing with "Login failed for user 'sa'. [CLIENT: <local machine>]"
I went to the Maintenance Plan and opened the Subplan. I clicked the "Manage Connections"
It has three tabs:
Name: Local Server Connection
Server: prod
Authentication: SQL Server Authentication
I clicked the Edit and it shows the Connection Properties:
It says: Enter information to logon to the server. "Use a specific Username and Password" is checked. Username is set as "sa" while the password is empty. I typed in the correct password and pressed Ok. When I go back again, the password still shows empty. I tried to run the plan and it again fails. Do you know why it is not showing the password as blank even if I try to save the password.

Hello.
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 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.

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!

Folks,
I have read the posts concerning login failures for the ASPNET user. I have a slightly different problem, as you can see from the title of this post.
My environment is a private domain that has two machines:
1) Windows 2000 server on which SQL Server is running. Let's call it FOO_SERVER.
2) Windows XP Professional on which I am running my IIS and .NET development environment. Let's call it FOO_WORK.
3) Let's call the domain, FOO_DOMAIN.
The user, ASPNET, is not a domain user, but a local user, so I do not know how to establish it as a valid login for SQL Server. But this is beside the point, anyway, as the error I am getting has nothing to do with the ASPNET user. It appears that a different username is being used to access SQL Server.
My connection string is:
"server=FOO_SERVER;database=pubs;Trusted_Connection=yes"
The error I receive is:
"Login failed for user FOO_DOMAINFOO_WORK$"
I am using the default settings in machine.config. Specifically <processModel> userName="machine" password="AutoGenerate" </processModel>
Thanks in advance for any suggestions.
-Joel

As an 'SA' I thought that you have permission to do anything on the server. Running an update command from Query Analyzer is throwing this error:
SQL Server 2000 SP3
Server: Msg 18456, Level 14, State 1, Line 1
Login failed for user 'sa'.
The table is in the dbo schema.
Has anyone seen this error before?

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.

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!
Any ideas why?
Regards
Ian

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.

Hi,
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;
Regards,
Ravi

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.

In an attempt to improve security for our web server/db server setup, we have a SQL Server 2005 server set for Windows authentication only and a web server (both behind a firewall together on a single local domain).
The web server is using IIS7, and the default NetworkService account to run the ASP.NET processes.
I've given the NT AUTHORITYNETWORK SERVICE account access to the database in question.
The SQL authentication fails, but the account failing is NOT the NetworkService account, but the <DOMAIN><COMPUTER>$ account.
Note that if I use identity impersonation with a specific domain account, I can get the app to work. However, I do NOT want to use impersonation, I want the default NetworkService account to work.
Does anyone know why IIS, which is supposed to be using NetworkService, is instead using the <DOMAIN><COMPUTER>$ account to connect to SQL, which is then failing?

Hi,
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?
TIA,
-Drew

Hey 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.

On computer 1, I am programming a C# utility to connect to a SQL 2005 SP2 Database. Here is the connection string.
Server=serverName;Database=database;User Id=DOMAIN/DomainAccount;Password=password;
I am using Visual Studio 2005 with .NET 2.0.
I have logged into Computer 1 with a different account. When I run the utility, I get a login failed exception. Here is the error I get from SQL 2005.
Login failed for user 'DOMAIN/DomainAccount'. [CLIENT: xxx.xxx.xxx.xxx].
Error: 18456, Severity: 14, State: 6.
xxx are filled with the valid IP address of the computer I am running the utility from.
When I log into the computer 2 with the same domain account, it runs with success.
Login succeeded for user 'DOMAIN/DomainAccount'. Connection: trusted. [CLIENT: xxx.xxx.xxx.xxx]
When I put Trusted_Connection=True; in the connection string, it connects as me and not the domain user I want to connect to.
When I put Integrated Security=SSPI; in the connection string, it does the same thing.
