How To Avoid Web Users To Connect To SQL Server Trought ODBC
Feb 25, 2008
Hi everybody,
i'll try to explain the problem with my bad english, so sorry.
In my firm i have a server (W2003 Server) with IIS 6.0 and SQL Server 2005 EE an it is joined in the main domain as all users and their workstation (window XP) are joined too.
The main role for this server is to be a web server and with IIS Manager I configured to verify user identities with Windows Integrated authentication without any anonymous access to web pages (ASP scripts).
I made a group called "Web Users" with read right on ASP scripts and his only one member is "Domain Users".
"Web Users" has of course rights to access this server from network.
This group is also a SQL Server login because it has rights to wiew an modify data at least in one db table trought ASP pages using ADO, but the problem is that they can also connect using ODBC.
Configuring SQL to accept only local connection i can avoid this, but as SQL Admin i can't connect too. So how is possible for web users interact with SQL only trought web pages ?
Thank you very much

I have had this issue just pop up. I have local users who can connect fine, but my users that require connection by VPN cannot connect. I get the server not available or access denied error. I did confirm that the VPN'ers are connected to the network correctly and can see that their shares and mappings are correct. Any ideas? Thanking you all in advance!!

Hi all
I have problem with making Connection between two computer through SQLServer and ODBC.
I have two computers which are members of a WorkGroup network with WindowsXP(sp2) installed.
on one computer i have installed SQL Server 2000 Enterprise edition with MIX Authentication mode enabled. Also i have created a LOGIN (Sql Server Authentication) with System Administrator ROLE (SYSADMIN).in that sql server environment .
But in another computer when i want to create an ODBC connection (ControlPanelAdministrative ToolsData Sources (ODBC)) to connect to mentioned Computer with Sql server,I receive the following Error:
Access Denied...Sql Server doesn't exist.
I have disabled Windows-XP firewall on both computers but still problem persists.
By the way these two computer have one Administrator Account with DEFFERENT Passwords.
Could anyone help me.? Any help greately would be appreciated.
Kind Regards.

I am trying out a simple ASP.NET application which includes access to an SQL Server Database. It works fine on my local machine when I connect to the SQL Server and use SQL commands (via C#) to access it.
But my web hosting provider uses ODBC drivers for database access (they support the SQL database type). I would like to find out how I should connect to my SQL Server database and program the access in order for it to be ODBC compatible, so that I can deploy it to my web hosting server. I should also mention that I am using Visual Web Developer 2005 Express Edition.
Thanks for any help or pointers.

We are running SQL Server 2005 in a Windows 2003 domain and I have a situation where some of my users are unable to connect to the SQL Server unless they are a member of the sysadmin group. Any attempts by these users to login result in a login failed,
Error: 18456, Severity: 14, State: 11
Which indicates that it is a valid user who does not have access to this SQL Server.
I have been able to narrow the failures down to the following situation:
Create a user, TestUser1, as a member of 1 domain local group TestGroup1
Give TestGroup1 access to SQL (standard public access to master)
All good. Login succeeds.
Add TestUser1 to another domain local group TestGroup2
Attempt to login to SQL Server -> login failed.
Add the user explicitly -> login failed
Add one of the groups to sysadmin -> login succeeds
It seems that as long as the user is a member of more than one AD group, and none of those groups is a member of the sysadmin server role then the user is unable to login. Obviously having all of the users as sysadmin isn't a workable solution, has anyone seen this issue before?
I have been able to replicate a similar situation in our test domain, but in that case the issue is resolved by adding the users explicitly to SQL Server (still not an ideal solution).
Interestingly, if I run the same test in our test domain but use global groups, it works. But unfortunately the network admin tells me the groups must stay as local.
Any help would be greatly appreciated.

Daniel Watkins

Hi,
When I'm using SQL server 2005, and ODBC drive €œSQL Native Client€? I get an error when executing the below given code. Error Message: €œTransaction cannot start because more than one ODBC connection is in use.€?
But this works well with SQL Server 2000 with ODBC drive "SQL Native Client" and in SQL server 2005 also when I used ODBC drive €œSQL Server€?.
I used aTrgConn.Execute(€œBegin Transaction€?) and it's working properly. But unfortunately I cannot use this method, because I want to run the same code with Oracle ODBC as well.
Is this a known issue in SQL Native client drive with SQL server 2005? Do you know a solution for this?
Please Help..............
Thanks in advance.
Code:
Dim aTrgConn As New ADODB.connection
Dim aCmdIns As New ADODB.Command
Dim aCmdUpd As New ADODB.Command
aTrgConn.Open sConnStr
Set aCmdIns.ActiveConnection = aTrgConn
Set aCmdUpd.ActiveConnection = aTrgConn

Hi,
I am not sure where to post this question, because is related to both TSQL & VBA Excel.
I am working under SQL SERVER 2000, and I have a query as described below:
Code Snippet
USE mydb
SELECT Block ...
GO
ALTER TABLE Block...
GO
UPDATE Block...
SELECT Block...
If I writte the query as shown above directly in SQL SERVER, it does work.
The issue is that I am generating the code trought VBA Excel, and when passing the SQL string to SQL, I get in SQL Server Managment Studio something like:
Code Snippet
"USE mydb
SELECT Block ...
GO
ALTER TABLE Block...
GO
UPDATE Block...
SELECT Block... "
with the " marks at the beginning and at the end of the script. In order to avoid the marks ", I need to erase the new line (return) before and after the GO statement, replacing the new lines by spaces and then the code looks like this:
Code Snippet
USE mydb SELECT Block ... GO ALTER TABLE Block... GO UPDATE Block... SELECT Block...
and DOES NOT work, getting Error because of the GO statement.
Thanks in advance for any help,
Aldo.

We have purchased an ERP system from a vendor which uses system DSN for all the reports. The system automatically creates DSN with Sa with SQL Server. The problem is the DSN is not working with AD users.
Active Directory server: Windows Server 2008 32 Bit.
SQL Server: Windows Server 2012 64 Bit. This server is already member of my Domain. e.g. CompDomain.com
What should I need to do in client PCs or Server to avail ODBC to AD users.

Win 2003 Small business server with IIS being used as a web server.
Our client app can log in and run queries, but our web app when trying to log in gets the message,
'SQL server does not exsist or access denied'
The system DSN's are both sql drivers and the configuration is name pipes. Our recomended specs use TCP/IP, but when I try to change it, it craps out on me. He's opened up his firewall completely to this new box and his old box, a Win2k machine can connect using TCP/IP. This machine is in a work group.
Any suggestions on what it might be??? :confused:

Hi,
I recently migrated our database from Access to SQL Server 2005. All the WinXP users can connect to the new SQL2005 database. But all the Win2K machines fail to log on. To diagnose the problem, I tried to connect from a Wind2K machine using an .udl file. The connection failed because "a provider failed to initialize".
The SQL2005 server is residing on a WinXP machine. Users log on via SQL Server authentication layer using a dedicated login that only has read/write privileges to one specific database.
Does anyone know a solution? Thanks in adance.
Regards,
Vladislav

Hello our organization has never had any problems getting users to connect to our SQL servers but we have grown a lot over the past year or two. Does SQL Server actually block connections if they go over the license limit? I don't have access to the servers to see the model used but I have been asked to look into this. I couldn't find any information on this so I decided to ask you guys. Thanks in advance.

I am running SQL Server 2000 sp4 in Win Server 2003. I have a DTS
packages which connects to FileMaker 6 files via the ODBC driver
installed with FielMaker.
The DTS packages work correctly when
executed directly. However, when executed from a SQL Server Agent job,
the same DTS packages fail. Always with the same message:
Error: -2147467259 (80004005);
Provider Error: 16394 (400A)
Error string: [FileMaker][ODBC FileMaker Pro driver][FileMaker Pro]Connect failed
Error source: Microsoft OLE DB Provider for ODBC Drivers
Searching
for info on the above message seems to indicate a permissions problem.
However, I am running the jobs with an full administrator account. All
connections and the FielMaker files reside on the one server.
Any help on this would be greatly appreciated.
Thank you.

Hi all,
I'm not a db guru and probably this is a very simple question for you, but I was wondering if it was possible to connect to a SqlServer using odbc without DSN.
I mean, I'm trying to connect to the db server from a linux (Fedora Core 8) workstation, using odbc drivers, but it looks like I can do that only using a DSN connection and setting properly the odbc.ini file. It doesn't work, if I use a connection like this from a PHP script:
$cn = odbc_connect("Driver={SQL Server};Server=MyServer;Database=MyDatabase",
"MyUser","MyPassword")
Does anyone know how to connect to SqlServer with a DSN-less connection? Could you explain me where is the error?
I'm using SQLServer2005, Fedora Core 8 with the last FreeTDS installed.
Please help!
Thanks million in advance.

Hi,
I wanted to know if there is a way to connect to my MSSQL without having to setup a datasource in the control panel.
Perferably I want to locate the database within my perl code instead. I don't want to have to setup a datasource each time I need a different database. Perhaps there is a way to pass the name of the database along with the username and password through the command line.
Any suggestions?
Thanks.

I am trying to connect to a database and run a query using vbscript. The problem I have run into currently is that I can not get the connection to open even though I know the DSN name it still says it can not find it. I am fairly new to vbscript so I am not sure exactly what it is looking for in the connection string so that it will find the database. Any ideas?

Hi,
I've been running some tests with a 3rd party application during the last few days, but the ODBC doesn´t seem to be working well.
The ODBCs are configured to go through specific ports, since there's a firewall between the server (production area) and the database (which is located in the dev area). If i press the TEST CONFIGURATION button after i configured the ODBCs, the test is successful, and the log file of the firewall monitor shows that the server is connecting through the designated ports.
But when i run the 3rd party application, the queries fail, showing an error that says "The server cannot be found or you don´t have access", after this error, another one appears, saying something like "Connection().opened..." - unfortunately I don't have the actual text, I'll try to post it as soon as i get them .
Just to make sure that the 3rd party app is doing its job, dev team wrote a simple VB6 app to query the database, and it shows the same error.
Both apps are running well in the dev environment, since dev machines don't have to go through the firewall, and both apps are using the ODBC configured in the same way as the server. I could think that the problem is the firewall, but the firewall logs show that the production server is trying to use ports 1433, 1434, 445 and 139, and there isn´t a single entry showing activity for the ports specified on the ODBCs configuration.
The database server is running SQL Server 2000, the dev pcs are running Windows 2000, and the ODBC driver version is 2000.85.1117.00.
On the Production environment the server that is trying to access the database is running Windows 2003 Server Ent Ed. SP 1 , and the ODBC driver version is 2000.86.1830.00
I hope some one outthere has any ideas to solve this problem, or at least any idea of what is causing this error, because i´m running out of them.
Thanks in advance.

When I begin Enterprise Manager and open a connection to a Server, it fails with a timeout error. But if I do a refresh and then connect again, it immediately works.
I have had similar symptoms setting up a data source for ODBC. When you initially logon to SQL Server to define the connection it times out. But then if you immediately try again it succeeds.
Furthermore one of my application programs fails to work (due to the timeout) on systems that have this behavior.
I have had these symptoms occur on 2 diferent workstations, but other workstations access the SQL Server with no problem.
All systems are WinNT 4.0; the engine is SQL Server 7 with SP2. The timeout is defined as 15 seconds so should be long enough.
Does anyone know what is going on, or how to fix it?

I am running SQL 2005 SP1 on Win 2003 Std x64 SP2. I get an error trying to connect using an ODBC System DSN connection. The ODBC connection gets the following error:
Connection failed:
SQLState:'28000'
SQL Server Error: 18456
[Microsoft][ODBC SQL Server Driver][SQL Server]Login failed for user 'sa'
The SQL Server logs the following error:
18456, Severity: 14, State: 8.
I have tried this with several SQL accounts. I am able to login to the SQL Manager with the accounts without issue. It is only when trying to connect via ODBC that I get the error. I am currently downloading SQL 2005 SP2 to see if this will help with the issue. Any other ideas would be greatly appreciated.
Thanks.

Hello,
I have created an SSIS package to retrieve data from a Lotus Notes database using the NotesSQL 3.02g ODBC driver.
In SSIS design mode, I can connect to the Notes datasource using the following connection string without any validation errors.
uid=UserID;Dsn=LN_Costs;
I have tried other variations of the connection string including every possible connection string parameter available to the driver as follows.
server=Server_Name;uid=UserID;Dsn=DSN_Name;Driver={Lotus NotesSQL Driver (*.nsf)};database=costing/productcost.nsf;username=UserID;encryptpwd=encrypted_password;maxsubquery=20;maxstmtlen=4096;maxrels=20;maxvarcharlen=254;keeptempidx=1;maxlongvarcharlen=512;showimplicitflds=0;mapspecialchars=1;threadtimeout=60;
Using the above connection strings in SSIS design mode, the datasource test succeeds, and an sql select statement in a datasource reader returns the table structure with no error.
However, when I try to run the package, I receive the following error.
SSIS package "Sales Data Load.dtsx" starting.
Information: 0x4004300A at Data Flow Task, DTS.Pipeline: Validation phase is beginning.

Furthermore, I have packages configured in SQL 2000 DTS to use the same system dsn without any errors.
Why doesn't this work in SQL 2005 SSIS?

Here's the context:
Database server:
- Remote machine running SQL 2005 Standard as a named instance
- Named pipes and TCP are enabled for remote connections
- SQLBrowser service is running
- Listening on default named pipe (\servernamepipeMSSQL$instancenamesqlquery)
Client:
- Vista Business machine
- Not in same domain as server, but on the same network (via Cisco VPN)
- SQL 2005 Express is installed (for use with local databases)
- Windows Firewall enabled
- Running Symantec Antivirus, Corporate Edition
Connectivity:
- I CAN connect to SQL 2005 databases on the remote server using "nperverinstancename"
- I CAN connect to SQL 2005 databases on the remote server using Excel 2007
The problem is that I cannot successfully create an ODBC datasource using the "ODBC Data Source Administrator" application. I'm using the "SQL Server" driver and trying to create a System DSN. I'm also running the tool with elevated permissions.
- When I try to use "servernameinstancename" as the server and TCP as the connection type, I get this error:
Connection failed: SQL Server Error: 18452; "[Microsoft][ODBC SQL Server Driver][SQL Server] Login failed for user ''. The user is not associated with a trusted SQL Server connection.
- When I try to use "npervernameinstancename" as the server and Named Pipes, I get this error:
Connection failed: SQLState: '01000'; SQL Server Error: 1326; [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen(Connect()).
Connection failed: SQLState: '08000'; SQL Server Error: 17; [Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied.
Help! I've really been beating my head against the wall on this one. It all works just fine with a Windows XP client machine.

Hi all
I am using Windows XP SP2 with a Sql server 2005 Express installation. I created a test db with a user called test, schema also test. I gave the permission connect, db_datareader and db_datawriter. I can now connect into this user using WinSQL. But if I want to connect using a application which is using ODBC, then I get the error:
[SQLSTATE=28000 - [Microsoft][SQL Native][SQL Server]Login failed for user 'test'.[Native Error=18456]]
Because I connect using ODBC, I think there must be the problem. But I have to connect with ODBC. There is no other possibility.
any ideas ?
Regards, Waff
I found this out:
The server collation is defined to: Latin1_General_CI_AS
If I create a new login id in lowercase, then ODBC will change it to uppercase and then the server refuse the access. But why. CI means case insensitive, so doesn't matter if upper or lower case. should.
How do you use a id in lowercase and connecto via ODBC ?
