scheduled task cannot open network connection J.Alonso 04-05-2006

Hello there everybody

This problem is one that has been making me crazy for a week. I hope someone
knows the key to solve it!!!

I got a couple of 2003 Servers. One is running Exchange/SMTP, the other one
is runnig a scheduled task. The task wants to send an email using the SMTP
server. To do so, the task program, initializes network, creates a socket,
and connects to port 25.

If i double-click on the program ( not running as a task ), being logged on
as the user who runs the task, the program connects succesfully to the SMTP
server and send the email.
If i execute the task and the user is logged in, it also works fine.

BUT, if i logg of from the user, and the task is programmed every minute,
the task would not be able to establish the connection. The connect function
fails, returning -1, and WSAGetLastError o getsockopt, with SOL_SOCKET,
SO_ERROR, do not give me and idea why connect fails. They both say, 0 as the
error, which means, unknow error.

Well, i have no idea about policies on windows 2003 server. All i know is
that the user can launch tasks, because i have two other tasks running with
this user, and those tasks do not fail. They can on the other hand establish
TCP/IP connections on the local computer.

Does anybody have a clue ??
