Some more information on my issue. The system is a production server
running exchange for one client. It is a new machine that was
recently built from know good media. It has been firewalled since it
has been built, during the build it was not open to the internet. Once
it was put into our production environment it had the following ports
open to it 25,80,443,143,110.

At this point I think the machine is cleaned. I am just guessing that
the machine was hit by some automated tool. I could kick myself for
not saving the files that I found on the machine and submitting to the
sites suggested by some on the list. I also did not save the registry
keys I found on the system, again another mistake on my part but I was
in a hurry to get the machine back into production. Sadly I wasn't
worried about gathering the information I needed to find out exactly
what happened to the machine.

Thanks for all of the responses I will have to add all of the
suggested steps to a process document on what to do when you find a
machine that has been compromised in some way.

Thanks,
Patrick
