Application deployment - database connection issue

Posted By:      Posted Date: September 29, 2010    Points: 0   Category :ASP.Net

Hi, I finished an intranet application using webconfig to store my connection string to an Access database which has linked tables to SQL Server 2005.

Everything works perfectly, but when I publish the application on a IIS server service, it seems like all connections fail... :(


I looked up on internet but found nothing on this. I think my webconfig file is correct :


    <add key="dbconnect" value="Provider=Microsoft.ACE.OLEDB.12.0;Data Source=//192.168.xxx.x/Websites/xxx/xxx.accdb;Persist Security Info=True"/>


Any idea why it happens?


thanks alot !

how to change the web application Database connection form Windows authentication to SQL Server acco

Hi, I have a web application created and Database connection authentication was given as Windows authentication. how can i change it to a SQL server account in MOSS 2007. Thanks in advance.

claims authenticated (FBA) user cannot open a connection to our custom application database

We have designed a custom sharepoint site. This site uses a membership provider that I implemented, and the users are stored in our custom application database. These are the steps I follow to reproduce the error: 1. Browse to our site. Select Forms Authentication from the default.aspx selection. 2. Enter in a username from our DB table. This user I have configured as a site collection administrator. 3. Login to the site. The user is authenticated by our membership provider and allowed access (ValidateUser returns true) 4. Browse to a page that attempts to connect to the custom app DB. 5. I get the following error when the page attempts to open a connection to our DB: 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server NOTES: The code that opens the DB connection is running with SPSecurity.RunWithElevatedPrivileges. Our application pool account has access to the database. My user can connect to the database fine as well as the user that our  application pool is running as. I have validated the connection string that is being used in the debugger, and that is correct.

Catch 22 Database Connection Validation Issue w/ BIDS and Production Server


I have a rather simple SSIS package that exports data through an ODBC connection from an IBM iSeries database and copies that data to a SQL Server 2005 database.  When I was designing the application, I was able to connect to the iSeries database and store the user ID and password with my BIDS project and copy the data with out any problems.  Great!

When I finished designing and testing the project, I loaded it to the production server.  The final test was to schedule the process so that it would run each night.  I didn't realize it at the time but the password that I had stored with the project in BIDS was removed from the package and various MS documentation stated that I should create a configuration file and load the password from there.  So, I made the necessary changes to the project, adding a configuration file.  The config file is in the Miscellaneous folder within the BIDS project, however, it isn't automatically copied to the bin directory when I build the project.  I have to manually save it to the server, and then after importing the project I have to manually link to the necessary config fields.

This fixed the problem with the server, however, now I can not get BIDS to save my password with the connection string from within the designer.  This is a huge problem.  I am exporting from 21 different da

Upsize Your Database: Convert Your Microsoft Access Application to Take Advantage of SQL Server 7.0


What if you need to convert an existing Microsoft Access 97 database application into a true client-server application that is based on a SQL Server back end? If you know a little about Visual Basic and SQL Server, it's easy to make your app take advantage of the power and scalability provided by SQL Server 7.0. Using some concrete code examples, this article takes you step by step through converting the native Jet queries in your Access application into stored procedures and pass-through queries that SQL Server can use. You'll also learn how to pass on parameters when your client-server app calls these SQL Server stored procedures and queries.

An example of packaging web application containing database upgrade SQL file

A few months ago, we have a blog talking about extending the web publishing pipeline to package database project deployed SQL file.  In this blog, I'll show step by step example of packaging web application with SQL Server database upgrade SQL file using Visual Studio 2010.  This way, we can generate a web package with incremental SQL script to certain database version.  The scenario may help distributions of a web upgrade package which needs to be installed on many different locations, each with their own SQL server database.   1. Create a Web Application Project 2. Add a new "SQL Server 2008 Database Project" to the solution 3. Prepare a development database, such as my test1 database as the following: 4.

Hi folks, I have more than one domains trusted each other, one user has already been granted access in the server, but I don't see it using Exec  xp_logininfo. I even tried adding the user as sysadmin. no problem for most of other users from the same domain. For another user, when I run the Exec  xp_logininfo, it returns: Msg 15404, Level 16, State 11, Procedure xp_logininfo, Line 62 Could not obtain information about Windows NT group/user 'INTL\RTxie', error code 0x534. what happened to these two accounts? is it a SQL issue or Active Directory issue? That domain has 15000 accounts across over 100 domain controllers. my domain has roughly the same amount users. they are trusted each other under same forest. Thank you in advance.

Problem with precompiling web application for deployment

Hi,I'm developing a web application consisting of several DLLs. I have no problem whatsoever compiling en building the application from within Visual Studio 2008 itself. But when I try to precompile the application (for deployment) from the VS command prompt, I get compilation errors.One of the errors is: "Could not load file or assembly 'wsCore' or one of its dependecies. The system cannot find the file specified".How can it be that VS2008 is perfectly capable of compiling the application from within the IDE and that same application can't be compiled from the command prompt?What am I missing here?

Looking for Clarification - Using a SQL Database MDF in an ASP.Net Application

I am looking to understand how to use Database files with ASP.Net web application projects. Very similar questions were posted, but I couldn't find quite the clarification I am looking for, so here's another post. I've been programming with ASP.Net for a while, but have always been in an environment where I had a full SQL server setup, and the databases were not file format. For the purposes of this project I am trying to keep it in .MDF format so that I can pass it on easily to my customer and let them do what they wish with it. The project is in Visual Studio 2010, a simple ASP.Net 4.0 MVC2 application that is to use EF 4.0 for persistence. Background Issue First thing I did was add a database to App_Data folder. It shows up on Server Explorer and I can manually add tables via Visual Studio - this should mean that the connection string and permissions and such fine I would think. So, next step. I created an Entity Diagram, built everything "model first" and used the Model to generate the database schema. Using the connection string in web.config, the generated SQL code runs, and says at the bottom of VS, "Disconnected". I go to the Server Explorer, and sure enough there's a red X next to the DB file. I expand the MDF, the little black arrow comes back, showing me I am connected. I try to run it again... and it does the same... "Disconnected"
