If this is a managed system, then if you have a software deployment tool like SMS, Tivoli,
or Unicenter can you just send down a job that runs something like Mantech's new
MDD.exe tool and write the RAM dump out to a \\servername\sharename\filename?
Otherwise, if you have admin access to the machine, can you psexec the MDD.exe tool on the
machine and write the RAM dump out to a \\servername\sharename share (mdd -o
\\servername\sharename\filename.dd)?
Doing either of the above would definitely alter the target machine more than the Firewire
method, but might be good enough depending on your situation.

evb,
There a number of potential techniques that are being used to deal with
locked machines. Though I must give my usual caveats that I would make
sure you know what you are doing and actually have experience with the
acquisition method before trying it as part of a real investigation.
Some of the techniques are hardware dependent, have the potential to
BSOD the machine, or are potentially destructive, so you may only get
one attempt. In some instances, it may be useful to get outside help.
As Jim and Jamie mentioned, performing acquisition via firewire is a
potential option. Details about this technique can be found on the
follow
site: http://storm.net.nz/projects/16. They even mention using a
CardBus firwire card. Others have successfully used techniques similar
to those presented in the Cold Boot paper
(http://citp.princeton.edu/memory/) or similarly, msramdmp:
(http://mcgrewsecurity.com/projects/msramdmp/)
Depending on how the laptop is configured, the hibernation file is
another alternative. There are also other hardware solutions but they
are very expensive.

AW

The method utilises Adam Boileau's Winlockpwn tool. Adam's Pythonraw
tool is available on Helix.

If I recall one "slight" issue with this method is the tendency to
BSOD. To quote Keith Lockhart at Access Data "This is a Bad thing!"

Hi evb,
I'm not sure, but maybe this will help (maybe someone else on here
knows better than I do):

I've never tried memory acquisition using firewire, but it sounds
like it might be worth a try.
All the best,

New subject: FW: Memory Imaging Using Firewire
David,
Thanks for the response. The only problem is that in evb's situation the
machine in question "was not a part of the domain and had not been subject
to auditing" and has "no network access". But in some situations that may
be a viable option depending on the types of systems involved.
My normal caveats also apply with untested kernel drivers used for
acquisition. Make sure you thoroughly test the mechanisms you plan to use
because you don't want that driver to fail on a critical server.
Thanks,
AW
