Hello Again.

I have a program that sends e-mails as follows:

Try
  Dim mail As New MailMessage
  mail.To = "m*@comp.com"
  mail.From = "m*@comp.com
  mail.Subject = "Test"
  mail.Body = "Testing123"

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate",
"1") 'basic authentication

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername",
NTUsername) 'set your username here

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword",
NTPassWord) 'set your password here

  SmtpMail.SmtpServer = "smtpserveraddress"
  SmtpMail.Send(mail)

Catch ex As Exception
  MsgBox("Error sending e-mail.")
End Try

Sending the e-mail using my program from a laptop connected via cable
to the network it works just fine.  However, when sending the e-mail
using my program through a wireless connection, it bombs with a cdo
error message.

My question is why does this happen on a wireless network when the same
computer can send e-mails when it's hooked up to the network with a
cable?

Thanks for any replies.

Mike.

I noticed that you're using a NT password - does your mail server reject
connections from the Wireless Subnet?

I don't think so.  The user that has this issue is able to send/receive
e-mails using outlook while wireless.

Any other ideas?

Thanks a lot!
