Default "Force shutdown from a remote system"

What do they really mean by this? I was able to shut down a server with no
users having this user right, using terminal services. I took everyone out
of this user right, and I refreshed the policy then connected to the server
via terminal services, and proceeded to shut it down, no problem. What kind
of tool does this policy expect the remote user is going to be using to
accomplish the shutdown? 'Cuz it sure ain't terminal services.

Any ideas appreciated.

Who are 'they" and where are you getting this from?
IE: methinks you left out a few details.

Generally speaking a terminal services login is considered
to be a local login as there is a winstation session.
Remote login is via such as a WMI shutdown command,
which is a small network transmission.

I believe the "they" is MSFT when "this" user right
was given a descriptive name, which differs in XP
where it is "Force shutdown from a remote system"

I think you are refering to a GP setting and this can override someone with
local admin privs on a box from executing a remote shut down with the
"shutdown" command.

e.g.

shutdown /s /m \\jimbo /e "I am being annoying and shutting down Jimbo's
workstation"

Kind regards,

Jimbo.

Ummm . . . no, this user right grants that capability,
not denies it, so it certainly cannot be used to prevent
an account from using their capabilities.

Default "Force shutdown from a remote system"

But, in terms of the _method_ of shutdown, the shutdown.exe command is the
only method this policy addresses?

No.

shutdown.exe is just a little exe MS made available at one time that has
stuck

I have spent a little time trying to see whether I can find a statement as
to just
exactly what APIs, what providers, what namespace classes' methodes are
covered by this settings.

Hoevers, all that I have found just says, as this from the W2k3 Security
Guide
quote
This policy setting determines whether users can shut down computers from
remote locations on the network. Any user who can shut down a computer could
cause a DoS condition. Therefore, this user right should be tightly
restricted.

/quote

In other words, the statements I have seen just make unconditional statement
that this allows use of remote means for shutdown, from which it seems that
all available ways are wired to obey thius right.

I know that when I use Wmi it is a requirement that one specify the shutdown
right when initially instancing the objects one uses (and of course this
explicit
request is only honored if it is granted to the account in use) because
otherwise
this is not enabled on the object obtained even when allowed to the account
used.

So, what exactly is the point of this policy, it doesn't really seem to do
anything.
