When i go to insert data into the sql server db i get an error when it tries to connect.
Heres the code
string sConnectionString = "Integrated Security=SSPI;Initial Catalog=;Data Source=localhost";
SqlConnection objConn = new SqlConnection(sConnectionString);
objConn.Open();
It is on an on button click event.
The area that shows up in the error message is
objConn.Open();
I would like to do a connection of asp.net page with Sql Server. Here I would like to read the Windows user account name and pass in the connection.The connection should be Windows authentication. IIS server and Sql server are installed in different machine. Here I am able to connect locally, When I am running from server, It takes windows account of Server.
so i can read local account(Where user is accessing the web application) and make windows authentication sql server connection.
While working with LINQ to ENTITIES I see that there is only a way to use stored procedure that is returning one entity only, or a view that is a join of two entities.
But what if I need in ASPX page to get two tables that there is NO connection between them, no join can be done between them at all.
I have one Stored Procedure that return the two tables, but entities don't support this right now.
I can split them to two Stored Procedure and call each of them separately.
i have a project running good (database and application both are in same server). some days before we've decided to place databse (sql server 2000) in different server.we created new server with windows server 2003 and Sql server 2000; nothing else is installed in it.And then i register new server's sql in old server's sql server. it connected successfully. even i can fire a query to new server from old server.
Both new and old server having windows server 2003 and Sql server 2000.
Now the problem :I CAN NOT ACCESS NEW SERVER'S DATABASE FROM MY APPLICATION.
I have changed my web.config as under :
OLD :<connectionStrings>
<add name="ConnectStr" connectionString="Data Source=OLDSERVER;Initial Catalog=DataExtractor;Persist Security Info=True;User ID=123;Password=123;pooling=true;Max Pool Size=50" providerName="System.Data.SqlClient"/> [code]....

I have a SQL server in my office. I can connect from my home development workstation website to the remote SQL server with no problems but when I upload the site to the web host and try and use the same SQL server it fails with 'A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible'
View 4 Replies Background: I use SQL server 2005 developer edition and visual studio 2008. Visual studio 2008 is running on a local machine with Vista business edition. SQL server is running on a remote server using Windows server 2003. Both computers are within the same domain.
Problem: First, I used the server explorer to connect to the SQL server. Everything works as desired. Then I write code to do the same thing. I keep getting the following error message:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid)
However, I used the exactly identical connection string as the one used in the server explorer. So connection string should not be the problem. In addition, I tried the test code in MSDN, which tells whether my domainusername can flow the network. It turns out the user name is fine. I also went to the SQL server management studio and found the login for my computer is NVCWeihao while my computer login name is NVCweihao. I am wondering if this uppercase letter really affects the connection.
We have a cient we are stting up that has 2 separate physical servers, one that is the web server the other the database server. Using impersonation we have been able to get the website to connect and retrieve data from the sql server so that part is not an issue. The problem is I have a windows service application that must be installed on the web server (as it process files downloaded to an ftp site) and it must be able to connect and write to the sql server as well.We tried adding a system.web block with the impersonation stuff to the app.config file which of course did not work. Can anyone tell me what/how we need to configure this properly?

View 1 RepliesCould not establish a connection to the database. If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider. I have set up a db locally which mimics the production DB, THe production db and website has no has no issues.
THis used to work till i had hard disk failure and had to reinstall all software and do the db from scratch. Used the table scripts and ran the aspnet_regsql. I am using sql server express 2008 asp.net 3.5 I am using custom provider for Roles and custom membership provider for Memberships. Pretty sure the problem is in the db permissions, though I have set up Users in the Security of the DB.
