Just open your command prompt and type nslookup if your DNS Server already setup then you get information otherwise you see "can't find server name for address 192.168.xxx.xxx default server are not available" default servern address:192.168.xxx.xxx

thanks

The SMTP server to use depends on your IT architecture ; if you have an intern mail server (like Exchange, Zarafa, etc.), you will have to use this one.
If you don't have an intern mail server, then you will have to use the smtp server of your internet access provider (and ask your question to its support team to get the right smtp address).
And last, you can open a free mail account (gmail, yahoo, whatever...) and use their smtp server, if possible.

You can Ping the Server IP via CMD
Example Ping www.google.com

I would be curious to see the procedure for that ^^
Outlook Express is a mail client, and, unless it is still configured, it is not designed to retrieve the smtp server address for a specific customer.

actually i found smtp address by typing ping smtp.server.com. that adddress is 216.69.186.201. and my code for sending email is
MailMessage Msg = new MailMessage();
// Sender e-mail address.
Msg.From = txtFrom.Text;
// Recipient e-mail address.
Msg.To = txtTo.Text;
Msg.Subject = txtSubject.Text;
Msg.Body = txtBody.Text;
// your remote SMTP server IP.
SmtpMail.SmtpServer = "216.69.186.201";
SmtpMail.Send(Msg);
Msg = null;
Page.RegisterStartupScript("UserMsg", "<script>alert('Mail sent thank you...');if(alert){ window.location='SendMail.aspx';}</script>");

and the error is
The message could not be sent to the SMTP server. The transport error code was 0x800ccc6f. The server response was 554 Your access to this mail system has been rejected due to the sending MTA's poor reputation. If you believe that this failure is in error, please contact the intended recipient via alternate means.

How can solve this problem.

What is your internet access provider ?
