Remote Access Using Windows Authentication
May 22, 2015
After 2 days of reading everything on the net about setting up Remote Access of my SQL 2012 Express using Windows Authentication I'm still not able to connect from a remote client onto my SQL Server Database Engine. I can get connected if using SQL Server Authentication. I have set all the parameters to allow access (read and tried everything from this site: URL.... but when I try using SSMS from the remote client to login I get Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (Microsoft SQL Server, Error: 18452).I've disable the firewall (Even though I have put in rules to allow port 1433 and UDP port 1434). Nothing is allowing me to connect. I've have tried every solution listed and got nowhere. My network is very simple with only three computers connected via a Linksys router (Two running Windows 7 the test client is running Windows 8.1). I can shared files and folders between all. Each computer only has one user defined (default admin user).
I need to make this work as I have to document it for other end users who will be using an application I created that requires an SQL Database and it needs to be accessible by other users on their network.

Using Bulk Insert Task extensively in our solution. Everything was working great till we deployed it in stage columns. The database server is different from application servers. We have ASP.NET web services driving SSIS packages on application server. After struggling thru several security issues to get this working (ended up creating an application pool with a domain account) we are now stuck with this problem. On a different note still don't understand what specific security permission is available to domain account that makes it work.
Read in some blog that SQL Server 2005 SP2 Beta had this (Bulk Insert) fixed but not in final production version. Is there a specific reason why this is so?
SSIS and the API is quite easy to work with but associated security and deployment issues are not always clear. A lot of answers seem to be coming from end users - thanks a lot to all for sharing your experiences - sadly not presented clearly in SSIS documentation.

Hi Guys,
My boss is concern that when using Windows authentication, a user can access any database that they have the rights too, using any SQL tool, and make unauthorised changes. He thinks that using SQL authentication is better because the username/password can be hidden from the user. (Access to the database is controlled by our applicatoin.)
Could someone knowledgeable in this are please comment.
Many thanks
Ray

Brief Description: I would like to use C# to write a program to access a SQL Server instance which is at another PC and using Windows Authentication. (I know how to use SQL Server Authentication, but I need to use Windows Authentication only.)
Detailed Description:
1. I have two PCs, and I would like to write a C# program in PC1. to access SQL Server at PC2 with Windows Authentication only.
2. I installed Microsoft Dynamics POS system. I install the POS Database with Windows Authentication only at PC2, but then I can install POS at my PC1, and when I set up the connection to the SQL Server, POS will pop up a dialog to ask me the username and password. I can just use the PC2's windows user account to login. Then POS can work fine. I would like to do the same just like what they did.
3. I tried the following code at the PC2 (the same PC as the SQL Server running), and it is running fine. But if I copy the same program and run it at another PC, then it will pop up a "Logon failuer: unknown user name or bad password.".
Microsoft.SqlServer.Management.Common.ServerConnection myServerConn = new Microsoft.SqlServer.Management.Common.ServerConnection();myServerConn.LoginSecure = true;myServerConn.ConnectAsUser = true;myServerConn.ConnectAsUserName = "username";myServerConn.ConnectAsPassword = "myPassword";myServerConn.ServerInstance = "myPCName\mySQLInstance";myServerConn.Connect();
Please help! Thank you!

I have a linked server defined on a SQL Server 2005 SP2 standard edition server using the IBMDASQL OLEDB driver. The linked server has been defined and working for months when used from a SQL Server authenticated session. I started converting our developers to Windows Authentication and access to the linked server is denied when used from a Windows Authenticated session. Here are the error messages:
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "IBMDASQL" for linked server "DB2ARUBA" reported an error. Access denied.
Msg 7350, Level 16, State 2, Line 1
Cannot get the column information from OLE DB provider "IBMDASQL" for linked server "DB2ARUBA".
The linked server security is defined to login to the IBM iSeries using a fixed user and password regardless of the login using the linked server.
In order to analyze the problem, I created one sysadmin SQL Server authenticated login and one sysadmin Windows Authenticated login. The Windows Authenticated login refers to a domain login having administrator priviledges on the local SQL Server box.
So, when I connect to SQL Server using the SQL Authenticated login, a query against the linked server works. When I connect to SQL Server using the Windows Authenticated login, the exact same query against the linked server fails with the messages above.
Does anyone know why?

Hi all,
I have a Windows Server 2003 with SQL Server 2005.
I´ve configured the following itens to allow remote connecitions:
[code]
WORKAROUND
Warning If you use Registry Editor incorrectly, you may cause
serious problems that may require
you to reinstall your operating system. Microsoft cannot
guarantee that you can solve problems that result from using
Registry Editor incorrectly. Use Registry Editor at your own
risk.To work around this problem, follow these steps on the
computer that Windows XP SP2 is installed on:
1. Make sure that the Log On As account for the MSDTC service
is the Network Service account. To do this, follow these steps:
a. Click Start, and then click Run.
b. In the Run dialog box, type Services.msc, and then click OK.
c. In the Services window, locate the Distributed Transaction
Coordinator service under Name in the right pane.
d. Under the Log On As column, see whether the Log On As
account is Network Service or Local System.
If the Log On As account is Network Service, go to step 2.
If the Log On As account is Local System, continue with these steps.
e. Click Start, and then click Run.
f. In the Run dialog box, type cmd, and then click OK.
g. At the command prompt, type Net stop msdtc to stop the MSDTC service.

Outbound check box.
i. Under the Transaction Manager Communication
group, click to select the No Authentication Required option.
j. In the Security Configuration dialog box, click OK.
k. In the My Computer Properties dialog box, click OK.
3. Configure Windows Firewall to include the MSDTC
program and to include port 135 as an exception. To do this,
follow these steps:
a. Click Start, and then click Run.
b. In the Run dialog box, type Firewall.cpl, and then click OK.
c. In Control Panel, double-click Windows Firewall.
d. In the Windows Firewall dialog box, click Add
Program on the Exceptions tab.
e. In the Add a Program dialog box, click Browse,
and then locate the Msdtc.exe file. By default, the
file is stored in the Installation drive:WindowsSystem32 folder.
f. In the Add a Program dialog box, click OK.
g. In the Windows Firewall dialog box, click to select
the msdtc option in the Programs and Services list.
h. Click Add Port on the Exceptions tab.
i. In the Add a Port dialog box, type 135 in the Port
number text box, and then click to select the TCP option.
j. In the Add a Port dialog box, type a name for the
exception in the Name text box, and then click OK.
k. In the Windows Firewall dialog box, select the name
that you used for the exception in step j in the
Programs and Services list, and then click OK.
[/code]
But, when the Windows firewal on the server is "On", remote connections
are not allowed, despite I´ve configured the Exceptions on the firewall.
Is there another task to solve this problem?
thanx!!!!

I have a windows based software application that connects remotely to a sql server 2005 and calls stored procedures. There is someone that I work with that is cautioning the company strongly that this is a bad thing to do in terms of security. Isn't this a very common thing to do? Assuming that the SQL Server installation is setup appropriately. Is this a bad practice?

We log ship our production database tansaction logs to a secondary database on a separate remote domain.
Incidentally, this was not set up via the "Ship Transaction Logs" wizard, but instead we had to use the various system stored procedures after restoring a copy of the database on the remote domain in standby mode.
We now have an issue where users are unable to access the remote secondary database without having sysadmin privileges. Clearly we want to avoid this!
We want to be able to use Windows Authentication mode on the server of the secondary database. But since the two domains differ, is it possible to even achieve this?
How can we set up read-only access for users on the secondary database without giving them sysadmin privileges?

Hello,
(Using win2k, sqlserver2k, framework 1.1)
I have an fairly data-heavy application that uses Windows authentication (Trusted connection/aspnet account) to connect to Sql Server. The site uses IIS basic authentication.
On the dev server everything works fine but when I move to the live server things get strange and it starts to crawl along. (Pages load OK but then it just crawls as it loads the datagrids etc. Sometimes it brings back incomplete/incorrect data )
BUT When I use Sql Authentication to connect to Sql Server and there is no problem at all!
Ok, there is something obviously wrong with the live server (which is identical setup to dev)but I dont know where to start.
Any ideas??

Hi all,
I've got two applications which both have a database on my MS SQL 2000 server. The problem is, one application must use Windows Integrated Authentication (which it is currently using and cannot be changed) whilst the other application which I'm trying to configure must use a SQL password.
Since the server has already been configured to use Windows Integrated Authentication for the existing database and application, how do I configure the other database to use the SQL password?
Thanks.

Hi all,
My work is using a shared application
which accesses a MSSQL 2000 database. To access the application, the
folder on the Windows 2003 Server is shared and users can access the
folder through a shared drive.
For the application to access the
database, it uses an ODBC connection to the MSSQL server which
originally used the SA password.
We have recently switched to using
Windows Integrated Authentication because we believe it offers a
higher level of security. However the only way in which we have been
able to enable this is to add the windows users to the SQL server.
The problem with this is that the
application sets permissions for individual users on what records
they can see within the database. We have found that by adding the
windows users to the SQL Server, they can bypass the permissions the
set by the application by simply using any application that can use
an ODBC connection, such as Enterprise Manager, and see all the
database.
One way around this would be to set up
domains of users with access privileges to the tables which reflect
the permissions set by the application, and configuring a view of the
data so they may only see the records that they have permissions to.
However to do this would require a high administrative cost to ensure
that changes made in the application are reflected in the privileges
of the SQL server.
Instead, is there a way the SQL server
can authenticate that the ODBC connection is coming from the correct
application using Windows Integrated Authentication?
This would allow the applcation to
determine security, and stop users from connecting to the SQL server
using other applications.
Alternatively, can the SQL server,
using Windows Integrated Authentication, also ask the application to
supply a username and password?
Any help with this matter would be
greatly appreciated.
Thanks!

Hi,
Say, I have configured my SQL to use Mixed Authentication. Now, I have a applicaiton which uses my SQL Server. The application just creates a database in SQL Server and uses the database to store its information.
This application also has a SYSTEM DSN under ODBC through which it accesses the database. For the application to access this database, should I only use SA (as my SQL instance is configured to use Mixed Authentication) or can I use Windows Authentcation too...
If I should only use SA, do we have a documentation which talks about this.
Thanks

Hi.
I wonder if it is possible to set forms authentication for report manager but leave report server "as it is". I need to authenticate users from external LDAP and can't use windows authentication for report manager, but I would also like to leave report server open for anonymous users. In that way authenticated administrators could create reports which anonymous users could read.
I tested the Security Extension Sample and got it working when I rewrote the authentication part with my own LDAP authentication.
If I have understood correctly, the report manager is just application inside report server so is it possible to use forms authentication with one application but still leave the report server with Windows authentication?

I am in the process of rolling out a sql server 2005 enterprise install and had a question regarding authentication. We will be providing sql hosting for a number of groups on our campus, many who are not using our campus-wide active directory, though they all have an AD account.
Windows authentication via the management studio appears to use your AD authentication tokens and will not allow them to enter a username/password combo. Is there any way to configure this?
I would like to use our campus AD for obvious reasons but if there is a requirement for passing tokens this isn't going to work right? It's also going to make database mirroring more of a challenge.
Thanks

In an effort to eliminate the need to code accounts and passwords into the VB Com calling stored procedures, I would like to use Windows Authentication. I have setup the account that the com is running under to have access to the database. How does this change my connection string. Do I just drop the account and password parameters or do I need to let it know somehow that I want to use Windows Authentication?
Thanks,

Hi,
I am wondering that do we need to create the separate login at SQL SERVER (server) for all the user using the application for the windows authentication?
How do the windows authentication works? I have a apllication and SQL SERVER (SERVER) running on the same machine. Any user from the same domain can access the application. Application is interacting with the DB through Windows Authentication. Now my question is whether do we need to authenticate each user from the domain at the DB level. That is to craete the login id for all the user for windows authentication.
Thanks,

Hi all,You're all stars, really helpful. Maybe one day i can be :)My question is regarding the authentication in Windows SQL Server 2005.We have setup a sa account. We purchase software from a third partythat runs on it. Before their software logs on the sql server as sa,and does its own access control, windows autentication takes over. Itslogs users on correctly i guess, using a more secure link via thedomain. However, I am probably blind, but where can we assign rights toeach domain user? I.e. stop XXY dropping tables, but allow ABC to droptables?I had a brief look through but could not find anything that stood out,in the SQL Manager.ThanksDavidP.S This is SQL Server 2005 Workgroup edition running on a 2003 windowsdomain server. Alongside a SQL 2000 server, which is running fine usingsa accounts.For those in the same timezones as me... have a good evening.
