Web App connecting to database using web.config file
I am using the web.config file to store my database connection string. Everything was working fine when I was running to applicaiton on my local machine.
However, when I deployed to the web I keep on getting this error:
System.Data.SqlClient.SqlException: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. at System.Data.SqlClient.ConnectionPool.GetConnection(Boolean& isInTransaction) at System.Data.SqlClient.SqlConnectionPoolManager.GetPooledConnection(SqlConnectionString options, Boolean& isInTransaction) at System.Data.SqlClient.SqlConnection.Open() at Dev_verI.BasicSearch.BindList() in c:\inetpub\wwwroot\dev_veri\basicsearch.ascx.cs:line 104
The line it points to reads:
conn.open()
Before that I had set up the connection like this:
strConnection = ConfigurationSettings.AppSettings["ConnectionString"];
conn = new SqlConnection(strConnection);
The relevant information in my web.config file is:
<appSettings>
<add key="ConnectionString" value="server = serverName;
Initial Catalog=dbname;integrated security=SSPI;
Connect Timeout=15;Network Library=dbmssocn;"/>
</appSettings>
Any ideas why I'm getting this error?
Thanks for the help!

Using this connection string, the application is trying to login to the SQL Server without providing any credentials.
You'll need to create a SQL Server user (not to be confused with Windows user accounts) and provide those credentials in the connection string (e.g. ...; user=aspnetuser; password=secret;...)
I have a blog.
Perhaps you'd like to read it.

In my application I'm using Windows authentication. Any user that is a member of the group that is allowed to use my application is also a member of the group that has access to the SQL Server database.
Is there anyway I can use the windows authentication to specifiy the credentials?
Thanks,
Wallace

There is a way using Impersonation.
What's happening at the moment is this:
When you make a request to an ASP.NET application, it is run under the ASP.NET account. You can, however, force the ASP.NET account to impersonate another user.
Unfortunately I'm not entirely sure how this is implemented, only that it is possible. A quick look through MSDN would probably tell you.
Sorry about that.
Good luck!

you can use Impersonation but it is more logical to use a new user in sql server
for impersonation:
<identity impersonate="true"/>

I have set impersonation to true.
Could the problem be that Anonymous Access is not turned off on the IIS server?
Thanks,

I don't thing so
Give necessary rights to the ASP.NET user on your database withh using Enterprise Manager
Scroll the databse and select Users
right click and select New Database User
Select <new> in Login Name combo
Select the ASPNET user from ... button
and on the Database Access tab check your database
I hope this solves your problem

Why we use Web.Config File for connection string wether we can use class Library for get connection for whole web Application please help me? Friend, Web.config has its own advantages. 1) Web.Config is used to store the important information like connections strings etc...so that it can be modified even after the code has been deployed to the server without compiling the entire application again. 2) Since it is a XML file, there is no need of building the project of you are going to change the connection strings.

Hi All, I'm doing some unit testing of a web application, and would like to use settings from a web.config file. Is this possible? Thanks much,- Mark I'd suggest keeping your Unit Tests in a seperate project and using it's own .config file. It will be a little repetition but it will help to keep things seperated for perf and reusability without bloating your production app. I agree with Curt. It is better to seperate options for testing and release version. This will decrease the job to be done once the unit testing process is finished.Haissam Abdul Mal...
