Blocking Specific IP From Logon
Nov 24, 2007
My company is apparently performing some sort of security test on our SQL Servers by sending malformed packets to it, which results in SQL Server throwing a Severity 20 error and resulting in my butt being paged every night at around 3 AM. As you can imagine, this ticks me off, but they refuse to stop this test. The [edited] error text from the SQL Log is as follows:
Source Logon
Message
Length specified in network packet payload did not match number of bytes read; the connection has been closed. Please contact the vendor of the client library. [CLIENT: 1.2.3.4]
Source Logon
Message
Error: 17836, Severity: 20, State: 1.
Is there a way to completely block a specific IP from attaching to SQL Server? Someone please let me have a complete night's sleep!

But I want to add: WHERE StatusType = (Active) and how to do this.

We have a "main" SQL 2014 server who imports XML files using SSIS in a datacenter. In remote sites (which are warehouses), there is an instance of SQL 2014 Express. A merge replication is setup, as every operations done on each site must be "forwared" to the main database, as some XML files are generated as output for an ERP system.
Now, the merge replication replicate all the data to the server on each sites. But a specific site don't need the data of every other sites, only the data relevant to itself (which is the warehouse code). Is there a way to replicate only the data relevant to each individual sites to the subscribers? Or is there a better way than replication to accomplish this?

I want to ship 500,000 aged transactions each night to an archive table and delete them from their source table in one or more logical units of work (LUW). Each row is approx 60 bytes and there is only one non clustered index on the source table presently.
I'm trying to weigh the pros and cons of 3 alternatives. One of them would basically insert the non-aged rows into tempdb, ship the aged records, truncate the table and then insert the tempdb records back into their source all in the same LUW.
For this alternative, I'd at least like to turn off logging when the records get inserted into tempdb as I dont see any value in logging that part of the activity. Is this possible?

Hi there !
Thanks for taking the time to read this thread.
I don't know whether anyone has this problem, but I am definitely not using the right keywords to search for a thread.
My situation is this...
I have a dataset that has values to fill cells to multiple tables in a report.
However, I only want to select specific data from the dataset to fill textboxes and others.
I cannot change the stored procedure, but the sample of the data is shown below:-
Row Stat Val
0 dtRpt1 02/01/2005
1 Value1 1
2 Value2 2000
3 dtMailSent 02/28/2005
4 Value3 0
5 Value4 5
6 Value5 658
I know it looks weird, but the row really represents which "row" or textbox is it to fill with the Val. The Stat Column is just a way to make sure that I am filling the right values.
so my new report would have multiple tables to denote different categories.
In my first table, I tried putting the cells as follows:-
(expressions are highlighted in italics and bold)
TextBox1 =IIF(Fields!Row.Value =0, Fields!Val.Value,"")
Table1
Column1
DetailRow1 =IIF(Fields!Row.Value =1, Fields!Val.Value,"")
DetailRow2 =IIF(Fields!Row.Value =2, Fields!Val.Value,"")
Table2
Column1
DetailRow1 =IIF(Fields!Row.Value =3, Fields!Val.Value,"")
DetailRow2 =IIF(Fields!Row.Value =4, Fields!Val.Value,"")
DetailRow3 =IIF(Fields!Row.Value =5, Fields!Val.Value,"")
DetailRow4 =IIF(Fields!Row.Value =6, Fields!Val.Value,"")
I only expect this report to print out one page holding the previous values.
However, it ended up printing like this
----------------------------------------------------------
Table1
Column1
DetailRow1 1
DetailRow2
Column1
DetailRow1
DetailRow2 2000
Table2
Column1
DetailRow1 02/28/2005
DetailRow2
DetailRow3
DetailRow4
Table2
Column1
DetailRow1
DetailRow2 0
DetailRow3
DetailRow4
Table2
Column1
DetailRow1
DetailRow2
DetailRow3 5
DetailRow4
Table2
Column1
DetailRow1
DetailRow2
DetailRow3
DetailRow4 658
------------------------------------------------------
I tried putting it into the headerrows instead of DetailRows, and it ended up printing the last value.
Is there anyway to do this ? print all the values out in one table ? I tried using textboxes, but I think I got my expression wrong.
Is this the correct expression ?
=IIF((Fields!Row.Value,"Dataset") =1, (Fields!Val.value, "Dataset"), "")
and it give me an error
The value expression for the textbox €˜textbox5€™ contains an error: [BC30455] Argument not specified for parameter 'FalsePart' of 'Public Function IIf(Expression As Boolean, TruePart As Object, FalsePart As Object) As Object'.
Appreciate any advice or suggestion for this scenario !
Thanks!

I am very early on in developing a website to track issues with projects which is tied to a SQL database. I have my Projects Table, my Users Table, and am creating a third table to track issues. I'm wondering what is the best way to assign specific users to specific data/projects. The user should only be able to view & update the projects assigned to him. He should not be able to see other projects. What is the best way to assign projects/data to the users to make sure they are only viewing their data?

Greetings,
After upgrading a SQL 7.0 WINNT 4.0 SP5 box to Windows 2000 SP1, SQL 2000 configuration I am getting the following error when some users try to connect to the server using Enterprise Manager;
"A connection could not be established to 'SERVERNAME'. Reason: Login failed for user 'NT AUTHORITYANONYMOUS LOGON'"
After doing some troubleshooting, I have found that this only occurs when I have the services started with a domain service account (this account is part of the domain admin global group and is a System Administrator in SQL as well) and it does not occur when the services are started with the System Account. Additionally, it also appears that this only occurs for some users and not all. However, these same users that are having problems on this server, can connect to other Database Servers using the "same" configuration.
Has anyone seen this. I have searched TechNet and found nothing that applies directly to this error. Any help that could be provided would be greatly appreciated.

I just started at a new company. The security stinks, everyone logs into the servers as sa (including many applications). I am taking steps to tighten security and restrict access to the sa login. I would like to capture some additional information at logon as an interim measure.
Can anyone assist me in automatically recording the following:
Host Name / IP Address
Login time
I realize I could periodically run an sp_who2 and capture the results - I also realize that if I turn on auditing, the logon will be written to the SQL Srvr LOG - I'm looking for an elegant / low impact way to capture the logon and host information.
Thanks in advance for any help.

Hi and thanks in advance :)
I was playing around with logins and windows groups and did the following:
Created windows group on my local computer called SQLAdmins.
Added my domain user to this SQLAdmins group.
Added SQLAdmins as a windows login on my local sqlserver instance.
Tried to login with my domain user but get "can't login..." message.
Is there something simple I'm not seeing?
thanks!

Hi All,
I'm using iis 4.0 with nt security to validate users. I'm trying to only pass the nt logon to sql and use
it as a filter when selecting records. I'm looking in the odbc driver and striking out there. What
variable is the logon assigned to so that I can construct it in the sql query???? How is this
done???
Direct email would be great!

Hi,
I am writing a web application in c# that is attempting to get the parameters from a report on a Reporting Services 2005 server.
I am using the following code:
SQLReportViewer.ServerReport.ReportServerCredentials = new ReportCredentials(UserName, UserPassword, UserDomain); SQLReportViewer.ServerReport.ReportPath = Rpt.FileName; SQLReportViewer.ServerReport.ReportServerUrl = new Uri(ServerUrl); Parameters = SQLReportViewer.ServerReport.GetParameters();
The Getparameters Line causes the following exception:
Microsoft.Reporting.WebForms.ReportServerException was unhandled by user code Message="Logon failed. (rsLogonFailed)" Source="Microsoft.ReportViewer.WebForms" ErrorCode="rsLogonFailed" StackTrace: at Microsoft.Reporting.WebForms.ServerReport.get_Service() at Microsoft.Reporting.WebForms.ServerReport.GetExecutionInfo() at Microsoft.Reporting.WebForms.ServerReport.GetParameters()
The UserName, UserPassword and UserDomain variables are all populated with correct data, as is Rpt.FileName.
The ReportCredentials class is a very simple implementation of the ICredentials interface - Code shown here:
-->
public class ReportCredentials : IReportServerCredentials { protected string _UserName, _Password, _Domain; public ReportCredentials(string UserName, string Password, string Domain) { _UserName = UserName; _Password = Password; _Domain = Domain; } //***************************************************************** public bool GetFormsCredentials (out System.Net.Cookie AuthCookie, out string UserName, out string Password, out string Authority) { UserName = _UserName; Password = _Password; Authority = _Domain; AuthCookie = null; return (true); } //***************************************************************** public System.Security.Principal.WindowsIdentity ImpersonationUser { get { return (null); } } //***************************************************************** public ICredentials NetworkCredentials { get{ return (new NetworkCredential(_UserName, _Password, _Domain)); } }
<--
I can use the same credentials to retrieve a list of reports from the report server (the report I am trying to access is in that list) and to log on directly by going to the URL of Reporting Services.
This is made more frustrating by the complete lack of detail in the error message, as it does not say why the logon failed, or give me a single clue about what is going on.
Has anyone seen this before and can tell me how to fix it, or is there something stupid in my code?
Thankyou.
Paul

Hi there!
Well this problem it's really driving me nuts!!!
I am using a CrystalReportViewer on a windows application which has an embedded report document...
The report (and the application too) is connected to an SQL Express server which is installed on an MS Small Bussines Server.
The server and the terminal PCs are under the same domain.
The app works flawlessly on the terminals, but when I open the form which contains the report I get prompted for logon to the SQL.. I have tried everything but it refuses to connect and i get a msg box : Logon failed.Please try again.
The sql surface area and the database have been configured to accept remote connections and mixed mode authentication (otherwise my app dosen't run at all), i have created sysadmin users(on the SQL), i have turned off the firewall but it is still refuses to connect.
I would like to mention that I have tested my app on my domain and SBS (I am not sure which version of SQL Server is installed) and I have used the develpment machine for the test. The logon is successful, even with the same account which the application connects (i mean the account included in the connection string)
Any ideas????
I appreciate your time,
thank you very much in advance...

SQL Server 2005 SP2 add LOGON TRIGGER feature,
but, if logon trigger have bug, it seems that anyone can connect to the sql server.
for example:
create trigger tr_logon1_bug
to all server
for logon
as
insert into t1 values(original_name(), getdate());
and, drop table 't1'.
the result, everyone fail to logon, even if sa. (may be..)
therefore, cannot disable/drop this trigger ...
So, Are there anyway to disable logon trigger,
or to connect by sa/Admin,
when logon trigger failed.

I have a report server that I restore from a copy of a backup from another SQL server on a daily basis. The problem is that the SQL logon in the report server does not work with the copy and I need to delete the logon in the database and reset the permissions for the SQL logon in order for the reports to run.
1. How do I enable the SQL logon to work automatically with the daily copy?
Thanks.

Hi
I am working on a replication database system, I will use SQL Server Enterprise at the main database and I’m planning to have remote databases with MSDE, I installed MSDE in a remote computer using a valid logon account for the domain in the domain controller (I had it connected for the set up). If I disconnect the computer from the network an restart the machine the Sql Server won’t start with the cache information.
How can I solve this problem?

Hello,
When I installed MS SQL Server 2000 on our client's computer I installed it under a local account using Windows Authentication as the server logon and am now accessing it using a network login (remoting into the same box). The result is that if I change the password for the local Windows account and reboot the server, SQL server cannot be restarted; I get an error:
A connection could not be established to (LOCAL)
Reason: SQL SERVER does not exist or access denied.
ConnectionOpen (Connect())..
Please verify SQL Server is running and check your SQL Server registration properties and try again.
I've changed the registration properties to use SQL Server Authenticaiton instead of Windows to no avail. Whichever connection option I use the server will not start unless I change the local account's password back to what it was when I installed. This works, but our client wants to have that local account's password changed for security/peace of mind. Any help or advice would be appreciated here :)
Thank you

I have found many references to this issue on the forum, but no solution that works in my case. I believe that I am lacking a fundamental understanding of a security issue so I will attempt to provide as much up front information as possible. I can publish SSRS reports from BIDS to my local computer but when I try and publish the same reports to a production server, I get a login dialog (which I cannot get passed). Here are the particulars. My environment is a home office. I have my computer (which works with the localhost designation) running on a workgroup network (not domain based). My server is another machine on the network (named €œserverone€?). Both machines are running Windows XP Professional. The BIDS project €œDebug€? property page has the TargetServerURL set to http://localhost/ReportServer. The €œProduction€? property page has the TargetServerURL set to http://serverone/ReportServer. I am logged on as an administrator but I cannot publish to the remote server (serverone) from my machine (localhost). I have also tried using the actual TCIP address of the server in place of the serverone name to no avail. I believe that my problem is related to authentication between the two SQL Server 2005 instances running on separate machines on a workgroup based network rather than a domain based network but I cannot find any information that might be useful under these circumstances. Now, here is my workaround (but this seems very wrong). From the logon dialog generated in BIDS, the user ID name was blank. When I attempted to remotely access the Report Manager on the server from my machine, IE tried to logon using the €œserverone/guest€? account. I added an administrator role to the guest account on the server and everything works as expected. As I mentioned before, this seems very wrong. Currently, both machines were set to use the €œlocal system€? account during setup, but I am not even sure what that means. I tried setting the server to use the €œNetwork Service€? account as suggested in one of the forum threads but that did not work. Any help here would be greatly appreciated as I am sure that allowing the €œGuest€? account to have €œAdministrator€? privileges is a bad idea.
