My page is not using a database but the asp.net is trying to connect to the sql server....
I didn't see any code from stack trace is going to connect the sql server, and who call the "System.Web.DataAccess.SqlConnectionHelper.CreateMdfFile" to raise this error... thanks.

An error has occurred while establishing a connection to the server.

Are you using any features such as Membership and/or personlization. Even though a page isn't using the database, something in the web.config file may be doing it. I often see an error in creating an MDF file when using the ASP.Net membership system and providing an incorrect connection string (thus forcing the membership system to try to create the mdf for itself and throwing that odd error).

I am using the Login component, FormsAuthentication, will they caused this error?
If so, what can I do? Thanks

re:

So, you *are* using a database, only you didn't know it.

Any time you have a "Login component", you also need the Membership database.

If you haven't created a Membership database,
and try to connect to a non-existent db, errors like the one you quoted occur.

Please review these links :

http://weblogs.asp.net/scottgu/arch...entication_2C00_-and-Security-Resources-.aspx
and
http://weblogs.asp.net/scottgu/archive/2005/08/25/423703.aspx

If you have any questions after you've studied thjose, let us know.

Thanks for the information, however the control of the membership is
currently controlled by the code, not by the database... or AD..
The code is as following, if "isValidUser" returns true, the page is ok, but
if it is return false, ASP.NET will try to create the database and raise the
error....


protected void LoginButton_Click(object sender, EventArgs e)
{
Session["Server_Name"] = "LocalHost";

if (isValidUser((String)Session["Server_Name"], frmLogin.UserName,
frmLogin.Password))
{
Session["Server_Username"] = frmLogin.UserName;
Session["Server_Password"] = frmLogin.Password;
FormsAuthentication.RedirectFromLoginPage(frmLogin.UserName,
false);
//Response.End();
}
}
private bool isValidUser(String ServerName, String UserName, String
Password)
{
DirectoryEntry myDirectoryEntry;
if (ServerName == "LocalHost")
{
ServerName =
System.Configuration.ConfigurationManager.AppSettings["LocalServerName"];
myDirectoryEntry = new DirectoryEntry(@"WinNT://" + ServerName +
"/" + UserName + ",user",
UserName, Password);
}
else
{
myDirectoryEntry = new DirectoryEntry(@"WinNT://" + ServerName +
"/" + UserName + ",user", UserName, Password);
}
try
{
Object native = myDirectoryEntry.NativeObject;
return true;
}
catch (Exception ex)
{
FailureText.Text = ex.Message;
return false;
}
}
 
ASP.NET ships with two membership providers: one that uses Microsoft SQL Server
as a data source and another that uses Windows Active Directory.

You appear to want to use Active Directory as a Membership Provider.

Do you have Active Directory configured as your Membership Provider in web.config ?
If not, the default membership provider is the SQL Server provider.

See :
