An other way of tackling the problem is going 'SNMP'. If you can find a
hole in that (write access, etc), you control the complete network. Why go
specific if it is possible to become "puppet master of then all". There
are some nice tools out there (commercial and open source) to find the SNMP
services and play with them (e.g. solarwinds, sans SNMPing and of course
nmap).
But more specific towards your questions:
=> smbrelay; smbrelay2 (Sir Dystic, Cult of the dead cow, man-in-the middle
relay attack, a very fun tool :-)

Subject: RE: penetration test in a Windows 2000/NT network
This sounds like a test from within the company. As it seems that
you will have physical access to facilities etc, would it be possible
for you to install something like a hardware key logger on a network
administrators workstation?
If someone has physical access to the LAN, I don't see why they couldn't
place devices on peoples systems. It may violate the rules for this
particular pen-test, but is something to think about. I see that you've
specified that physical access to Win2k systems is possible, and are
interested in not modifying the administrator account -- hardware
keyloggers
seem like an ideal solution.
What about wireless sniffers? Does the target use any wireless networking
at their facility?
