Check http://www.cert.org They have a section with best pratices if a
windows or UNIX system is compromised, they also have good info about to
prevent intrusions. Furthermore get some good books like "hacking exposed".

BTW. You signed up to this list probably from securityfocus, this is also an
excellent site to get info.

Subject: Windows NT intrusion

Last week, I had a clients' NT Server 4.0 machine show definite signs of
compromise... all sorts of odd ports listening, including some traceable
back to WinGate (which we never installed!), and some others that were
known as some IRC-related stuff. With a UNIXy OS, I have a pretty
decent idea of how to find out what happened, when, etc. and maybe even
clean up. But Windows? I took the easy route... on Saturday, I just
nuked the OS, installed W2K, patched, etc. But are there any sites that
have good documentation about post-mortems on Windows boxen? Or even a
class in the San Diego area?

Also, any thoughts on things I can do to make things easier on myself...
I've found some tools that can send the NT system logs to an off-host
syslogd. Are there any Tripwire-like tools for NT? Any such thing as
an immutable bit?
