recovering client data.

Microsoft has documented a way to create a memory dump on demand [1].
Could this be considered sufficient to preserve the system's state?

An option - Virtual sessions of Linux (Knoppix, Insert, etc) may be
possible on a Windows platform.

Since a compromised box may have some sort of rootkit installed on it,
how reliable would you consider the output of a forensic tool running on
the compromised system? Wouldn't a rootkit (at least theoretically) be
able to manipulate the data which is requested by such a tool or script?

I'm less than a novice to forensics, so excuse me if these questions
sound stupid.
