Gary,
I'm actually about half a chapter ahead of you... LOL that is
PRECISELY what I was doing when I got your message... I think I have
it working... uhm... sort of... LOL This is REALLY INTERESTING.....
The program fails to find the SMTP server on my build machine.
However, if I run the assembly ON my server, it DOES find the server,
whether I leave the SmtpServer property blank (to default to
localhost) or actually specify the DNS name of the server. I know it
is reading that property though, because if I misspell the server
name, it will fail (as it should)... BUT, Gary, here's what I think is
REALLY interesting...
If I go over to the server and run the program from over the network
(like going to Explorer and typing
\\buildmach\c$\VSProjects\SmtpTest\Bin\Debug\ and then clicking
SmstpTest.exe), the thing fails. Copy the EXE file though (and the
dll that supports it), over onto a local directory on the server (like
My Dcouments), and click it, and it runs fine. In both instances, the
thing is executing in the context of local machine environment; the
only difference is the path over which it gets the initial EXE and
initializes the dll. The only thing I can come up with at this point,
is that some kind of request is sent off to the SMTP service to tell
it, "Hey, I have something for you." The server comes back and says,
"Oh yeah, well initialize this dll....." and the server tries to
initialize a dll that is on the remote machine sending the mail, and
for some reason, that fails. That sounds stupid and almost completely
baeless, but I can't think of any other reason why the program would
run from one location, and not another, especially on the same
machine. Interestingly enough, if I do just the opposite... That is,
go back to the build machine, and try ot run the program outside of
the VS environment, it still blows up. If I try to run it remotely
off of the server, it still blows up, so that blows a hole in my
previous theory..... This is making me nuts!!! LOL How am I supposed
to troubleshoot something like this? :(
Any feedback?
Jim
