Error In Sending Emails Through Web Application/unable To Read Transport Connection, Net_io_connectionclosed
My team is working on an Library application in asp.net 2.0/VS2005.

This application needs to send emails, so have implemented smtp access in the code.

Access to smtp email server is also granted. The same code is able to send email to the desired email-id when debugged from local machine But from the server machine, while sending email the application generates an exception at System.Net.Mail.Send method.

Error is : 

' unable to read transport connection, net_io_connectionclosed '

Error "Unable To Read Data From The Transport Connection: Net_io_connectionclosed" When Trying To Send Email
I'm trying to send an email from my ASP.NET website using the following code (obviously replacing the hostname, username and password with the actual values):

Public Shared Sub Send(ByVal ToEmail As String, ByVal FromEmail As String, ByVal Subject As String, ByVal Message As String)
Dim mm As New MailMessage(FromEmail, ToEmail, Subject, Message)
Dim smtp As New SmtpClient("hostname")
smtp.Credentials = New NetworkCredential("username", "password")
smtp.Send(mm)
End Sub

When trying to send out the mail I'm receiving this error: "Unable to read data from the transport connection: net_io_connectionclosed."

System.Net.Mail - 'Unable To Read Data From The Transport Connection?
I have a C# application whose sole purpose is to read a couple of tables (MAIL_QUEUE and MAIL_RECIPIENTS) in a database and send out emails. One table contains the message text, and subject line (MAIL_QUEUE). The other table (MAIL_RECIPIENTS) contains the recipient email address and any CC and BCC addresses. Anyway, when this application is deployed on the customers server there seems to be some issue with the number of CC addresses that can be specified in the email address. I can specify 99 CC addresses and the email gets sent out successfully. As soon as I add one more (for a total of 100) CC addresses, an exception is thrown when I call smtp.Send(oMsg). The error is 'Unable to read data from the transport connection: net_io_connectionclosed". The moment I remove that one extra CC, the email will be send successfully. I've asked the customer if there are any settings or limitations in their Microsoft Exchange settings and they say no. I can run the application on my local server (SQL, and mail server) and there are no problems with sending out messages with more than 99 CC addresses), so I know the code is working correctly.

Unable To Read Connection From App.Config
I am unable to understand. Hopefully someone out there has faced a similar issue and knows the fix. I am creating DAL for my project using class library. In my class library I want to store the connection string in APP.Config file and I have created and saved it.

The problem is when I try to access my connection string by name using ConfigurationManager.ConnectionStrings[Name], it returns null. When I try to access connection string using number like ConfigurationManager.ConnectionStrings[0] It  returns a strange connection string i.e. (data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true)

I want to clearify here that I have not deployed the website yet and its on my local file system so there is no link of this library with IIS.

Installation :: Unable To Add Data Connection From VWD2008 Express To Remote SQL Server
I am using the free download of Visual Web Developer 2008 Express Edition. I have a MSSQL2005 database in a remote server. I am trying to add a data connection through the "Add Connection" dialog box (not directly using code). I am using the following parameters: Data Source = Microsoft SQL Server (SqlClient), Server Name = <my server name>, I am using SQL Server Authentication with my correct <username> and <password> to the database, and I am selecting a connection to my database by entering my correct <database name> (I am not attaching a database file).

When I click on Test Connection, I get the message "Test connection succeeded" which would imply that the connection is ok. However, when I click OK to establish the connection, I get the following error: "The system cannot find the file specified.". 

I am unable to add the connection.

Connectionstring objProducts = // redaing the connection string.

Membership Select Provider / Unable To Modify The Connection
I've done this before but can't remember how for the life of me. I used aspnetreg_sql.exe to create the membership tables in my database. But now i cant seem to be able to point my web app to the correct database. In the provider settings in asp.net management interface i only see a radio button with the label "AspNetSqlProvider" but I can only test it (in which it always fails). I can't modify the connection.

Configuration :: Unable To Access Connection String In Machine.config
I have a Windows Service I have developed in Visual Studio 2005 (C#).

It accesses a database using a connection string in machine.config.

On my Windows XP Pro 32bit (SP3) machine, it works correctly.

On my new Windows 7 Pro 64bit machine, it throws "object not set to an instance of an object" when it gets to the line where it's trying use the connection string.

This is the 'object' which is not set in Windows 7:

ConfigurationManager.ConnectionStrings["MyDatabase"].ConnectionString

The machine.config has the same connection string set up on both machines.

A .Net 2 website transferred to the Windows 7 machine has no problem accessing the same connection string.

I have tried a bunch of different permissions on the machine.config and its containing folders, and setting the service to log in as Admin, but I don't know exactly what permissions are required.

DataSource Controls :: Unable To Alter Connection Timout Property?
Im using two stored procedures to write and update values in a SQL DB.  Im using the SQLDatasource update method. When I run the webpage on my development server everything runs fine.  When I try and run the web page on my Live server I get the following error :System.Data.SqlClient.SqlException: Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding This always takes 30 seconds to fail - and looking at google it seems that this is a connection timeout error.In my web.config file I have  updated the connectionstring line to include a timeout setting :

connectionString="Data Source=myserver;Initial Catalog=ReportServer;Integrated Security=True;Connect
Timeout=10000"

But this hasn't helped at all.

Active Directory/LDAP :: .Net MVC 2 'Unable To Establish Secure Connection With The Server' Error?
We're  having an error similar to the one detailed here.  We get the error noted above when trying to do AD authentication from our .net (3.5) mvc 2 app. This is our first .net mvc app ...

http://forums.asp.net/t/1161047.aspx

- We are re-using a forms auth library written for a .Net 2 app

- that library/app/config used a service account with min. privileges for binding to AD

- This error occurs in VS 2008, have not tried deploying the app to a server yet (a little early for that)

- like the other user at the previously referenced thread, I can get the 'unable to establish ...' error to go away and display the log on page by putting *MY* credentials in instead of the service account (but not successfully authenticate)

- moving the service account into the same AD OU as my account does not seem to change it ... only using my account credentials does.

- trust level is set to full

Is this some  odd permissions trick that is new with .Net 3.5 (even though the ADmembershipProvider is still a 2.0 libary)? This should have nothing to do with MVC itself.

Config looks like this (very standard, like every one else's)

[Code]....

The line/portion highlighted in the debug/stacktrace is:

type="System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
