  NTDSUTIL is a low-level, raw access, powerful sort of tool.
Generally you shouldn't be using it unless things are moderately badly
broken already.  In that kind of situation, you want as little
"helpfulness" between you and the data as possible.  You wouldn't be
using it if things weren't outside the expectations of the higher
level tools, so by definition you're in a situation where you're
claiming to be smarter than the higher level tools.

  The following excerpt from Neal Stephenson's essay, "In the
Beginning... Was the Command Line", explains the sort of tool that
NTDSUTIL is.  NTDSUTIL is like the Hole Hawg.

===== The Hole Hawg =====

The Hole Hawg is a drill made by the Milwaukee Tool Company. If you
look in a typical hardware store you may find smaller Milwaukee drills
but not the Hole Hawg, which is too powerful and too expensive for
homeowners. The Hole Hawg does not have the pistol-like design of a
cheap homeowner's drill. It is a cube of solid metal with a handle
sticking out of one face and a chuck mounted in another. The cube
contains a disconcertingly potent electric motor. You can hold the
handle and operate the trigger with your index finger, but unless you
are exceptionally strong you cannot control the weight of the Hole
Hawg with one hand; it is a two-hander all the way. In order to fight
off the counter-torque of the Hole Hawg you use a separate handle
(provided), which you screw into one side of the iron cube or the
other depending on whether you are using your left or right hand to
operate the trigger. This handle is not a sleek, ergonomically
designed item as it would be in a homeowner's drill. It is simply a
foot-long chunk of regular galvanized pipe, threaded on one end, with
a black rubber handle on the other. If you lose it, you just go to the
local plumbing supply store and buy another chunk of pipe.

During the Eighties I did some construction work. One day, another
worker leaned a ladder against the outside of the building that we
were putting up, climbed up to the second-story level, and used the
Hole Hawg to drill a hole through the exterior wall. At some point,
the drill bit caught in the wall. The Hole Hawg, following its one and
only imperative, kept going. It spun the worker's body around like a
rag doll, causing him to knock his own ladder down. Fortunately he
kept his grip on the Hole Hawg, which remained lodged in the wall, and
he simply dangled from it and shouted for help until someone came
along and reinstated the ladder.

I myself used a Hole Hawg to drill many holes through studs, which it
did as a blender chops cabbage. I also used it to cut a few
six-inch-diameter holes through an old lath-and-plaster ceiling. I
chucked in a new hole saw, went up to the second story, reached down
between the newly installed floor joists, and began to cut through the
first-floor ceiling below. Where my homeowner's drill had labored and
whined to spin the huge bit around, and had stalled at the slightest
obstruction, the Hole Hawg rotated with the stupid consistency of a
spinning planet. When the hole saw seized up, the Hole Hawg spun
itself and me around, and crushed one of my hands between the steel
pipe handle and a joist, producing a few lacerations, each surrounded
by a wide corona of deeply bruised flesh. It also bent the hole saw
itself, though not so badly that I couldn't use it. After a few such
run-ins, when I got ready to use the Hole Hawg my heart actually began
to pound with atavistic terror.

But I never blamed the Hole Hawg; I blamed myself. The Hole Hawg is
dangerous because it does exactly what you tell it to. It is not bound
by the physical limitations that are inherent in a cheap drill, and
neither is it limited by safety interlocks that might be built into a
homeowner's product by a liability-conscious manufacturer. The danger
lies not in the machine itself but in the user's failure to envision
the full consequences of the instructions he gives to it.

A smaller tool is dangerous too, but for a completely different
reason: it tries to do what you tell it to, and fails in some way that
is unpredictable and almost always undesirable. But the Hole Hawg is
like the genie of the ancient fairy tales, who carries out his
master's instructions literally and precisely and with unlimited
power, often with disastrous, unforeseen consequences.
