How to avoid error when creating SMTPClient from VB.NET
Hi,
I've written a simple VB.NET program to send an eMail. Part of the code creates the smtpClient using the following code:
Dim smtpClient As SmtpClient = New SmtpClient(SMTP address, 25)
The program works well if I run it from my local disk and the eMail is correctly sent to the given address.
On the other hand, if I run the program on our internal LAN, I get the following error message when it tries to create the client and the eMail doesn't get sent:
"Request for permission of type 'System.Net.SmtpPermission
I suppose that our Network Manager should change a setting for certain priveleged users (i.e. those allowed to send an eMail from my program). Can anybody suggest which setting should be changed?

This was the clue that put me on the right track. I didn't even know of the existance of a .Net configuration utility.
