"Failure sending mail" error with System.Net.Mail

Hi all,

I'm using System.Net.Mail (Framework 2.0) to send emails on scheduled
basis. This works great on Windows 2000 server. Rently we have
upgraded our servers to Windows 2003. Since then some of the emails
are failing from being sent to people. Ratio is like 1 in 30 are being
failing, I thought it is the mail size issue and I have unchecked the
mail size limit on SMTP server. Still I couldn't figure out why few
are not going out.

Any help is appreciated.

Thanks in advance.

Shil,

What is your idea how we can help you?
We know now that it fails sometimes on server 2003 while you think it did
not on 2002 (or have you a way to proof the latter?)

Proof... yes. We do log the actions on each email that goes out. On
Windows 2000 server they never failed. Now when we have transferred
the same code (VB.NET 2.0) to the Windows 2003 server, couple of the
emails are failing to go out.

I know that I have posted this question before, but it is still unresolved and I don't know where to turn to next. I have code that is creating a user (works fine), then sets the account flags (works fine) and then sets the password (fails). Here is the pertinent information: Ex.InnerException.Message: Logon failure: unknown user name or bad password. Ex.Message: Exception has been thrown by the target of an invocation.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
