I have created a vbscript that will e-mail
the number of devices in each state and the total number of devices being
monitored. I then use the system scheduler to run the script to send the
status every morning and afternoon. It requires you to install a SMTP Active-X
object from Ostrosoft. If you would be glad to provide the script if you
want to play with it.

monitoring under Windows 2003
Thanks for those details. I'm definitely getting
an intermittent down. The target servers are two Windows 2003 machines,
and one Fedora machine running BIND 9.2.2. I'll see if I can get a packet
capture at some point today.

I'll probably try replacing the DNS
