Tracing Failed Logins
Jul 19, 2001
SQL 7 profiler has an event in the Misc. category of Failed Login. It does not, or at least I cannot get it to, produce any output when a failed login occurs. Any hints?
I tried this because every week or so I get this in the error log:
Login failed for user 'Admin'.
It occurs several hundred times within a minute or so. It obviously has to be an automated process as you couldn't click a button or press a key 13 times a second.
The login does not exist as a SQL login so I can't tell which database it is trying to get at. Any suggestions gratefully received.

My SQL Server 2005 SP4 on Windows 2008 R2 is flooded with the below errors:-
Date  10/25/2011 10:55:46 AM
Log  SQL Server (Current - 10/25/2011 10:55:00 AM)
Source  spid
Message
Event Tracing for Windows failed to send an event. Send failures with the same error code may not be reported in the future. Error ID: 0, Event class ID: 54, Cause: (null).
Â
Is there a way I can trace it how it is coming? When I check input buffer for these ids, it looks like it is tracing everything. All the general application DMLs are coming in these spids.

The event log is showing a ton of failed sa logins. The server is connectedto the net. I am assuming this is a dictionary attack to get the sapassword. I am trying to find out if this is an inside attempt or from theoutside. While the profiler will tell me which program or script is sendingit, how do I find out which ip address(s) from the net is doing this?--John Dalberg

We're using a canned app that only uses SQL Server logins (it will NOT use Windows logins to access SQL Server)
SQL Server logins seem to lack even the most rudimentary security features such as expiring passwords and automatic disabling after a set number of failed logins. Bad. Bad Microsoft.
Has anyone figured out a way to graft this on after-the-fact?
I can do it in an awkward fashion by auditing failed logins and going back to read the error log, but this isn't real time by any stretch.

Hi,
I need to be able to get info about failed login attempts which need to be running all the time and logging info such as hostname , application name, host machine, etc. The best way I can see to do this is by crerating a trace. Then loading the info from the trace into a table for later use by using fn_trace_gettable. But this requires that the trace be stopped and the definition removed for the trace file to be populated.
Is there a way to be able to log this info constantly into a table without having to stop and then recreate another trace. Also it requires that the table created by the function is dropped.
Anyone any idears?
Thanks

HI guys,
I just restored a database on a new server with a backup(complete backup stored in backup device) from another database on another server using the "with move" option. In fact here was my process:
Alter database ngauge SET SINGLE_USER WITH ROLLBACK IMMEDIATE
restore database ngauge
from disk = 'C:Program FilesMicrosoft SQL ServerMSSQLBACKUPgauge1.BAK'
with move 'NGAUGE' to 'C:Program FilesMicrosoft SQL ServerMSSQLDatagauge_Data.MDF',
move 'NGAUGE_Log' to 'C:Program FilesMicrosoft SQL ServerMSSQLDatagauge_Log.LDF'
Alter database ngauge SET READ_WRITE
it worked.
But it did not move the 98 or so users/logins...from the source database
what is going on??? what am I doing wrong??!!
Please help!

Hi,
We are running MSSQL 2000 on a reasonably powerful dedicated Win2k system Dual 2.4 Xeon Procs, 2 GB of RAM, Ultra 160 SCSI disks.. blah blah blah.
Our primary use this database server is for our Coldfusion Application servers. We host about 50 or so databases.
Of late, we have been experiencing random failed logins for certain databases. These failed logins are logged to the event log on the server. They randomly; queries executed against a datasource configured on our application servers trying to get data from the database fail with a login failure when other times they will succeed. I am confused about this issue. Could an issue where the SQL Server is overloaded cause a login failure for a database?

I just applied instcat.sql to my SQL Srvr 2k sp4. At first it broke my replication with some cursor errors. Applying the latest instcat.sql fixed the problem, however one of the distribution agents would not start (i'm not sure if instcat had anything to do with it) giving me a "Login failed for user 'NT AUTHORITYANONYMOUS LOGON'. The process could not connect to distributor 'DistributorName'. The step failed." error.
Any suggestions would be greatly appreciated!
Thanks!

I was checking the logs because of some failing backups and found literally hundreds of enties for failed logins for user sa. This is does not seem to be related to the failed backups, because even after fixing the problem (disk space), the entries continue to pile up.
Needless to say, the information provided in the log is a bit sparse: date and time, source (Login), message (Login failed for user 'sa'.). If that is actually enough to go on, then there must be some way of cross-referencing this information with that found somewhere else. Is there a 'somewhere else' or are there other things I need to do in order to track this down?
I don't suspect any malicious intent, but I'm not ruling it out. My main concern at this point is twofold: to gain a better understanding of system management; to identify and correct the failed login.
Any recommendations, whether tools, documentation, or otherwise are very much appreciated.
Ron.

ok, first, I know... I forgot to run a backup of the master database, and I forgot to run a script to caputure logins. Not that that is out of the way... I need to recreate the logins under the Securities tab below the databases. All the company databases have the user names and passwords assigned to them, but they are not able to login, because they are not able to authenticate to the SQL server first.
Is there a script that someone has that will copy the company database security info for the users and recreate them in the SQL security tab?
I know that I can rebuild them manually, but I need to delete them first in the application software, then delete them from the databases, and then recreate them in the application software... and as simple as that sounds... it is a slow moving process.
Any assistance would be greatly appreciated.
Thanks,
John

Hello,
I would move a Database to another server. I try to use DTS but I have problems with this process because DB have big tables, I think. I try to use DETACH and ATTACH procedures but logins doesn't export. And more, in new server there are already logins from another DBs.
What's the best way to solve this problem?
Please, help
Thanks

I am a systems analyst and work with an app that runs against 2 SQL Server DBs. Though I have some familiarity with SQL Server and SQL, I am not a DBA.
The app executable is tied to a Windows service.
When we install the app, we run a process that builds 2 dbs to include:
Tables, indexes, stored procedures, views and user accounts.
SQL Server is set up for mixed mode authentication.
Normally, the dbs run off the local db user accounts which are tied to local logins with the same names.
We have a client that wants to remove our standard logins so that they can run on only a Windows login.
I know I should be able to tie the db users to a Windows login.
And I can do the same for the service.
But I am at a loss as to how to get this done.
How do you associate db users with a Windows login?
When I have tried sp_change_users_login I get an error that the Windows login does not exist. (Though I have added the Windows account to the DB.)
Hope this all makes sense.

I would greatly appreciate any help with this problem, as I've been digging thru every resource I can find looking for a solution with no luck.
I'm going to be monitoring a database for all SQL statements containing INSERT, DELETE, or UPDATE. I'm grabbing the user name, time, and the entire text of the query. I can already do this programmatically, no problem. The problem lies in this. When I set up a trace on SQL Server 2000 using the system stored procedures sp_trace_create, sp_trace_setfilter, etc, and set the trace to save to a trace file, I find that I must first stop the trace then close the trace before I can use fn_trace_gettable to get the information that I want. However, this is undesirable, because this database may be accessed worldwide, and stopping the trace to read the data could cause the trace to miss some users making changes. Does anyone know how that I could get my trace data into a table so that I can just run queries on that table to get my data? It's very important that I not stop the trace to do this. Thanks for your help!

I am fairly new to SQL Server. I am writing a tool in stored procedureto identify locks in a table. I have already written the basic frameworkof the SP. It will reside in master database and take two inputs. Databasename and table name. From that it will show all locks at that instanton that table of that database. If table name is omitted, then it will showlocks on all tables.I am using syslockinfo, spt_values tables and joining with SP_WHO procedureto get the table name, user name and the session id.Now what I need is to find out which SQL is causing the lock and since whenlock is being held on the table. Which tables in master database holds therequired information.TIA.Ravi

Hi,
I am using sp_executesql to get some data but it is not working. Is there a way to actually see the actual statement where subsituted variables are replaced with the actual values.
SET @SQLString = N'SELECT Top(1) @Passenger_OUT = Name, @Ticket_OUT = TicketNumber , @TAN_OUT= [TAN] '
+ N'FROM dbo.Table1 WHERE 1 = 1 '
+ Case @MatchAmount When 1 Then N' and Amount = @BillingAmount ' Else N'' End
+ Case @MatchTicket When 1 Then N' and LTrim(TicketNumber) = STUFF(STUFF(@TicketNumber,Len(@TicketNumber)-@RemoveRight+1,@RemoveRight,''''),1,@RemoveLeft,'''') ' Else N'' End
+ Case @DaysDiff When 0 Then N'' Else N' and DATEDIFF(d,@BillingDate , InvoiceDate) <= @DaysDiff ' End
+ Case @MatchName When 1 Then N' and Left(Name,@CharsToMatch) = Left(@PassengerName, @CharsToMatch) ' Else N'' End ;
SET @ParmDefinition = N'@BillingAmount decimal, @TicketNumber varchar(15), @RemoveRight tinyint, @RemoveLeft tinyint, @BillingDate datetime, @DaysDiff tinyint, @CharsToMatch tinyint, @PassengerName varchar(35), @Passenger_OUT varchar(35) OUTPUT, @Ticket_OUT varchar(15) OUTPUT, @TAN_OUT varchar(25) OUTPUT';
EXECUTE sp_executesql @SQLString, @ParmDefinition,@BillingAmount=@BillingAmount, @TicketNumber=@TicketNumber, @RemoveRight=@RemoveRight, @RemoveLeft=@RemoveLeft, @BillingDate=@BillingDate, @DaysDiff=@DaysDiff , @CharsToMatch=@CharsToMatch, @PassengerName=@PassengerName, @Passenger_OUT=@Passenger_new OUTPUT, @Ticket_OUT=@Ticket_new OUTPUT, @TAN_OUT=@TAN_new OUTPUT;
Print @SQLString will gives the statement with variables and I need to see the actual data plugged in during runtime.
If I take the ouput of @SQLString and run it myself by adding variables it works fine
Thanks

There is a bug in one of the service packs where Profiler (7.0) only traces one server (regardless of the server you tell it to trace). Can anyone tell me how to fix this or point me to a KB article? I thought this was fixed in SQL 7 SP 3, however I'm experiencing this problem with SP3 installed.

Hi There,
I hope someone can assist me in tracing the cause of a problem I am experiencing. I have a Web Server with ASP's querying the SQL Server 6.50.416 database. There is only one user db on this machine and yet I am running out of User Connections (current setting 2000) and memory (128MB RAM). Also, NT repeatedly experiences Stack Dumps. I have used the PRINTDMP utility to try and trace the cause of the error. The "Input Buffer" section of the Stack Dump (symptom dump) contains the following:
SELECT FK_SUB_PRODUCT_GROUPING, FK_SUB_PRODUCT_NAME FROM RESOLUTION_PRODUCT_SUB_PRODUCT WHERE FK_PRODUCT_CODE=1072 order by FK_SUB_PRODUCT_GROUPING
Is this SQL Statement the cause of the Stack Dump? Does anyone have any other ideas on what may be causing my problem. Any help would be greatly appreciated.

I have a very simple piece of code (see below) which when executed sometimes takes around 7 minutes and sometimes around 3.5 hours. the difference is that during the 3.5 hours there is a lot of querying of the table being updated. But I don't know how to find out if this is the case. How can I find out whether my process is waiting (for locks or for any other reason) - is there a trace or debug facility within the tandard Microsoft Toolset which I can use.
Regards
Colin

Hi guys,
We have 2 databases: DataBaseSource and DatabaseDestination. We need to truncate all the data in DatabaseDestination and put all the data from DataBaseSource into DatabaseDestination.
What is the best way to do that, we have a lot of data?
And what is the best way if we also need to keep a trace of what happened in case we wanna go back and see what happened.
Also , pls, if we use DTS, is it possible that if someone wants to see what the DTS does, is it possible to read the DTS? I mean if I give a dts to sompeone, a new DBA guy in 2 years for example, how can he know what a certain DTS does? I mean does SQL 2005 put the DTS packaege scripts somewhere or is there a friendly way to know what a DTS dsoes exactly?
Also the trace to see if something went bad is important for us?
Sory if i didn t express myself well enough, and thanks a lot for your help.
Rachid.

Guys,what I need is a tool which gives details on the choice of anexecution plan by the SQL Server. For example, the cost for a hashjoin might be 200 and 100 for a nested loop, and therefore a nestedloop is used. Same thing for the access paths for each table/viewinvolved. In Oracle, we turn on event 100053 to see this kind of info.ThanxDaniel

Has anyone worked out how to trace SOAP/HTTP Endpoints in SQL 2005 SP 2?
I'm not having a particular problem, just want to know how things work, such as which layer is responsible for the HTTP Authentication. I've traced the HTTP.sys stack using logman.exe (see http://www.thelastpickle.com/2008/03/22/tracing-sql-soap-endpoints-through-httpsys/) .
I cannot see any SQL Profiler events, and I've tried setting trace 7801 and 7803 as described in http://www.sqljunkies.com/Article/5CCAC423-1407-4A36-AF71-ED6A67D9646A.scuk#_Toc52964195 but they do not result in any logging.
thanks
