OK
We have always used sql servwer login to the servers for all our applications for out intranet apps
And we use windows auth to do development
So when we do that we logon to wuindows, and then just connect, with no password required
But how does an application "logon" to connect to a database
Is it just in the connection string just like sql server auth
or is it different?

I have a child package where the ConnectionString property of a Connection Manager is set by a Parent Package Variable Configuration. I set up a script task that brings up a message box with the value of the ConnectionString property right before the dataflow task.
MessageBox.Show(Dts.Connections["CPU_*"].ConnectionString.ToString());When I run the parent package, the message box shows that the connection string is changing with every iteration, but in the dataflow it always draws the data from the same source.
The connection manager is an ADO.Net type, RetainSameConnection is set to False, and I've been researching this for days.
(Update 2/23/2015): To make this stranger, when I look at the diagnostic logs, they tell me that when the new connections are being opened they are using the new connection strings.

Hi all,I have a Windows 2003 server, which is also a terminal server forapplication, with sql 2000 installed. My company has developed anapplication that uses SQL 2000 as its database. The application is aclient/server one. In each client computer there's a link to theapplication on the server. There is no problem with Windows 98,Windows 2000 pro, Windows xp pro clients, but the windows 95 onescannot log in to the database. The log of the application shows thefollowing error:connection error -2147467259. Cannot open database requested in login'database name'. Login fails.Till a week ago the application was running on a Windows 2000 serverwith SQL 2000 install and the W95 clients had no problem connecting tothe database, so my guess is the error has something to do withWindows 2003 server, but what'causing the error?I tried to install a newer version of MDAC (MDAC 2.5, the last versionof MDAC you can install on W95)but with no success. By the way W95clients have no problem accessing shared folder on the Windows 2003server.Any idea?ThanksMarino

I added a connection (ADO.NET) object by name testCon in the connection manager - I wanted to programmatically supply the connection string. So I used the "Expressions" property of the connection object and set the connectionstring to one DTS variable. The idea is to supply the connection string value to the variable - so that the connection object uses my connection string.
Then I added a "Backup Database Task" to my package with the name BkpTask. Now whenever I try to set the connection property of BkpTask to the testCon connection object, by typing testCon, it automatically gets cleared. I am not able to set the connection value.
Then after spending several hours I found that this is because I have customized the connection string in testCon. If I don't customize the connection string, I am able to enter the "testCon" value in the connection property of the BkpTask.
Is this an intrinsic issue?

I have a domain user account through which I can log on a machine. The machine allows me to use this domain user account to create DB in SQL Server using windows authentication. How can I define a connection string to connect SQL Server? My connection string is like:
string str = "server=(local);uid='"+userName+"';password='"+password+"';database='master';connection timeout=15";
This one works on another machine where I use SA account. But this one does not work using windows authentication. I tried to use domainnamemyname as user name, but failed.
Could any one give me some suggestion?

Hello,
I have a problem with SqlClient (WindowsCE 4.2 & .NET CF2.0 SP2). PDA is connects on PC via USB-cradle and ActiveSync 4.0. PC is in the LAN and SQL Server 2005 is in the LAN too. I can't connect to SQL Server 2005 (after connection.Open() I get exception "PlatformNotSupported"). When I use SQL Server 2000, it's O.K.
Can I connect on the SQL Server 2005 from Windows CE 4.2?
Thanks.

Hi all,
I think I can do this, just want to check
Can I have an sql server database (mdf file) on a server and allow windows applications at different site manipulate the database.
As far as I am concerned the only thing that needs to be configued is the connection string..is this correct.
[i would rather use windows applications rather than asp pages]
If I can, the best way to manipulate the database is to use stored procedures. How would I do the following to create and execute the following proposed procedure:
Insert data into a table
Update another table as a result
Execute the store procedure on a form to execute these two statements
Thanks in advance

Hi All,
I have written a windows service using VB.NET that connects to a database and performs several tasks. The service is working correctly and has been fully tested against SQL Server 2000. I have recently moved to SQL Server 2005 and now, the service will not connect to the database.
I have setup and tried several different users, but none work, I get the following message:
Login failed for user 'OEESYSTEMS'
The server instance, username and password I specify are all correct.
The service is running on the same server as SQL Server. I can connect through a web application, and through ODBC. The server is set to use SQL server and windows authentication, and is setup and successfully allows remote connections.
It looks like SQL server sees that a windows service is trying to connect and does not allow it.
For the love of god, can anyone help with this issue.
Thank you.

Hi all-
I setup a new ODBC connection to MS SQL Server 2000 on Windows XP and keep getting the following errors when I try to
either register a new SQL Server 2000 group within Enterprise Manager or test the new ODBC connection:
Current configuration
- MS SQL Server 2000
-Windows XP
-ODBC 3.85.1117
Errors:
I. Within SQL Server 2000 Enterprise Manager
Error: SQL Server connection open
II. When I test the ODBC connection:
Microsoft SQL Server ODBC Driver Version 03.85.1117
Running connectivity tests...
Attempting connection
[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]Specified SQL server not found.
TESTS FAILED!
Now here is what has me totally confused:
I can use the command line ISQL to access the database on the server and IP is all correct and port is available.
Any tips how to get this ODBC working?
Thanks

Every so often a client Windows 2000 pc that is trying to access the report server cannot connect to it (page cannot be displayed).
If I go over to the server itself, the same report runs fine.
After several minutes, it is possible to connect to the report from the Windows 2000 client machine.
Report Server is running on a Windows XP Pro machine.

In testing new patches, I tried Windows 2003 Server SP2 and our JDBC connections stopped working. I uninstalled SP2 and they started working again. Anyone know where the problem is?
I have already read pages of documentation, but I will keep looking. Please let me know if you know the setting that needs to be changed. I'm assuming it is a new "security enhancement" but I'm just not sure exactly where.
Thanks in advance.

I am running a C# Windows Service as ".Administrator" account.
It cannot make connection to SQL Server 2005 and gives the following error:
(An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Like it couldn't find the SQL Server 2005 .(SQL Server is installed in Windows 2003 Server Enterprise ed.)
However when I debug my service as Console application it connects successfully.
I am still in trouble.. please help me out.

I am a SQL DBA involved in accomplishing various activities using Enterprise Manager by regestering servers of various countries.
Now as the NT Team has gone for auditing implementation in all the servers in OS lever, they find Access violations from the workstation from where I connect to the server. This does not happens if I unregester the Servers from Enterprise manager and use only query analyzer.
Note: We have our own users in OS as wel as in SQL SERVER .
Its Urgent!!! Please help!!!

I have an application that talks to a SQL backend using an ODBC DSN connection. It works fine when running on a 32bit machine but fails in the 64bit environment. The DSN is setup properly on the 64bit box and the Test Connection returns sucess. However when my application tries to use the DSN to connect to the database I recieve the following error.
IM002 - Data source name not found and no default driver specified.
The data source name does exist, it's in the ODBC.INI and in registry. As mentioned above the Test Connection succeeds in the ODBC Administrator so logic would dictate that it's setup correctly.
Any help would be appreciated.

i'm using sql server 2005 express edition as the database server for my web application. Right now, i want to deploy it and the problem is, my hosting is using sql server 2000. So, is it possible to deploy my database that has been created in sql server 2005 in the sql server 2000? I'm afraid that the connection string for sql server 2000 is different from sql server 2005. In addition, i'm using forms authentication in my web application. So, some data regarding to the forms authentication like dbo.asp_net.membership table, dbo.asp_net.roles table is in my database. Is it the table that has been created like dbo.asp_net.membership can be used in sql server 2000 since it is created by asp.net forms authentication function?

I have the Visual Studio 2005 Team Suite trial version and the SQL Server 2005 trial (which came with team suite) installed in my machine.
When I installed the SQL Server 2005 I installed it in the Windows Authentication mode. So every time I open SQL Server 2005 it doesnt ask for Username/Password (Its greyed out). The only thing available were:
Server Type: Database Engine
ServerName: ServerSue
Authentication: Windows Authentication.
Here is my Problem:
I created a small application in C#. In the web.config file I created the following:
<appSettings>
<add key="resumecon" value="SERVER=ServerSue;database=Resume;"/>
</appSettings>
Then in the Code behind I created the following string:
string strResCon = ConfigurationManager.AppSettings["resumecon"].ToString();
Then in method (for a Login page) I created the connection string as follows and wrote code to insert some values into the Resume database. I called this method on a button click event.
SqlConnection conLogin = new SqlConnection(strResCon);
When I run the page and when I click the button I get the following error:
Login failed for user ''. The user is not associated with a trusted SQL Server connection.
I think some thing is wrong in the addkey of webconfig? How do I change this?

I am slightly confused about SQL Server connections strings. When I used the following connection string:
string strConn = "server=deciusawa;database=xxxx;uid=xxxx;pwd=xxxx";
I get an error saying "Format of the initialization string does not conform to specification starting at index 13. "
I spent ages trying to figure out why this was and I eventually discovered that adding an "@" symbol before the string fixed it, i.e.
string strConn = @"server=deciusawa;database=xxxx;uid=xxxx;pwd=xxxx";
Most of the examples I have seen to not use the "@" symbol so I am just wondering what is does and when you need to use it?
Thanks,
Mark

I am using SQL server express 2005. I can drag and drop a grid control on to my web form and choose the data source to point to a SQL server database. Then datais nicely displayed on my web form.
Now I need to manually create my connection to the database as I need to read from a text file and then populatea database table with those values I read from the text file. I have not had any success with this though and I am stuck and need some help.
Below is my C# code and I list the web.config code where my connection string is stored.
Note that I can trace into the C# line of code below. If I then do a "Quick Watch" on "myConnection" in the debugger, the followingerror message is displayed:
ServerVersion 'myConnection.ServerVersion' threw an exception of type 'System.InvalidOperationException' string {System.InvalidOperationException}
So I don't know what the problem is here. If someone can help me out I would be forever thankfull
C# code:
SqlConnection myConnection = new SqlConnection(ConfigurationSettings.AppSettings["TheDividerConnectionString"]);
Here is the connection string as defined in the web.config file:
<connectionStrings> <add name="TheDividerConnectionString" connectionString="Data Source=BVCOMPUTERSQLEXPRESS;Initial Catalog=TheDivider;Integrated Security=True" providerName="System.Data.SqlClient" /> </connectionStrings>

I've been using my old connection string for years, and it has worked fine in 1.1 and 2.0 betas
It's pretty basic: "Data Source=Computername;Initial Catalog=MyDB;Integrated Security = true"
For some reason, I am having trouble getting this to work on SQL Server 7 with the release code of asp.net 2.0
What does work is to open up TCP/IP on the server network utility (I
usually only use named pipes) and change the connection string to "Data
Source=123.123.123.123;Initial Catalog=MyDB;Integrated Security = true"
The latter (with the IP of the box istead of 123....) works great, so I
can be sure that my IWAM account has correct permissions to access the
DB.
Does ASP.NET talk with sql servers using a different protocol than
Named Pipes by default? I'm a bit spooked to open up TCP/IP on my
production box as I saw the damage that SQL Slammer did a few years
back, and want to keep everything as locked down as possible.
Thanks,
John

I am using asp.net 2.0, and am attempting to connect to a SQL Server 2000 database. When I run the web page either in the debugger, or by viewing it in the browser, I get the following error message:
Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection.
I think that maybe my values for uid, and pwd are not correct? If this is the problem, then I don’t know what their values should be? Should uid always be equal to sa ??(If so why?)
Also I don’t know what the password should be. I don’t know what the name of the password as it was assigned over two years ago when I installed sql server 2000. I might need some instructions on how to find this value in SQL server.
Someone please help me if you can. Here is a snippet of the code I am using:
String sqlStmt = "INSERT INTO LogIn (UserName,PassWord) VALUES ('JohnyRocket','FastestRocket99')";
SqlConnection sqlConn = new SqlConnection("server=localhost;uid=sa;pwd=;database=MyWebSite;");
SqlCommand sqlCmd = new SqlCommand(sqlStmt, sqlConn);
sqlConn.Open();

would this be the same query string for MSDE database? I'm quite new in MSDE but I know that except for the tools that comes with SQL Server and its size, they are practically the same...
