While trying to send email using<code> SmtpClient obj_SmtpClient = new SmtpClient(); obj_SmtpClient.Host = ""t; obj_SmtpClient.Send(s_from, s_recipients, s_subject, s_body);</code>I get the error message:Failure sending mail. Unable to connect to the remote server An established connection was aborted by the software in your host machine at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.InternalConnect(EndPoint remoteEP) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Int32 timeout, Exception& exception) SystemSMTP is installed on my Windows XP Sp2 laptop. I have also tried disabling the Windows firewall but still the same error. The SMTP server is a Microsoft Exchange Server that is part of the same domain as myself. I was logged on to the domain while running the email code.There is an excellant article on ORCS web by BradKingley (http://www.orcsweb.com/articles/sending_smtp_authenticated_email.aspx) on sending authenticated email using username/password, however what I need is how to authenticate in a purely Microsoft environment. Any suggestions as to how to fix this problem, gratefully accepted.
