Hi,

I've just gone to Windows Server 2003 / Exchange 2003. I had Windows
SBS 2000 before. As there's no upgrade path that I could find, I
basically have a clean install on my server.

Anyhow, most of it went smoothly, and I'm now able to send and receive
email without any problems. The server is the only Exchange / DNS
server in the domain, and like I say, everything is working fine,
apart from the following...

If I reboot the Server, I am able to send email, but not able to
receive email ( I get a '3008' 'Non-Delivery Report' message in the
Event Viewer for every email that is sent to me ). However, if, after
the reboot, I then go into Exchange and stop the SMTP Virtual Server,
and then start it again, everything works fine again. And it stays
working until the next reboot.

The only other errors I'm seeing are in the System Event Viewer. I get
'2012' and '2013' 'SMTP could not connect to DNS server' events about
once every hour or so. However, in spite of these errors, I am able to
send and receive email without problems ( assuming I've stopped and
restarted the SMTP Virtual Server! ).

The server is the only DNS server in the domain, and it is pointing to
itself for DNS, with forwarders set up for my ISPs DNS Servers. The
SMTP Virtual Server also has these External DNS server addresses. Once
I've restarted the SMTP Virtual Server everything works perfectly,
which makes me think that in general everything is set up well enough,
or I wouldn't be able to use email in the first place!

Any ideas why I need to stop and restart the Virtual Server? And ideas
what those 'SMTP could not connect to the DNS server' errors are
about, and how to fix them / get rid of them? I've found quite a few
entries about them in Google Groups, but most suggestions don't apply
to me, and I haven't been able to fix them. I don't even know if
they're errors I should worry about!

Thanks in advance...

Jason.
