	Some may have gotten this, sorry.  I sent it from the wrong acct:

Users:

	There are inexpensive tools to take care of this for you, not that
MS lacks the free ones...oh yes, they do exist.  Dameware NT utilities is
one great 3rd party tool.  If you're an admin and haven't touched this one
you're missing out.  A few click of the mouse and all you can hope for can
come true.  It also can be used on both sides of the fence....it is one of
my main utilities for working my way into networks.  Now, be warned all, it
may not have a button to do the exact function you're looking for, but
rather has the ability to perform batch functions...even across domains and
standalones (given the correct creds), and that's really the issue here,
right.  If'n one has been blessed with "Creativity" then that person may
just be able to use it beyond the help, faq and user files....but don't
assume you have it (creativity), most don't.

	(Now that I see the rest of the orig post I'll comment on the IDS
part):

	Weak-ass admins ONLY complain that IDS' make work for them AND that
they are worthless.....Boo hoo, *we* have to research, *we* have to
interpret and *we* have to take action....WAAAAAAAAAAAAAAAAAA.  

	So, some joe-hacker that has intelligence so far beyond most
any-type admin (especially Windows), and he wants into your network.....the
complaint is that ya might have to do some analysis?  Just like in the
Navy...Officers don't know shit!  That's why they're called Security
Analysts, clown...cause they analyze security threats and take actions.
Hell, I don't know ANY OS that I would trust to make an informed decision on
taking action.  And if yer staring at a 1/2 million alerts then perhaps you
need to hire someone competent to tune your IDS....and if you have, perhaps
you should FIRE THEM!

	I'm not surprised to hear it though...especially from an edu, you
guys are your biggest enemies.  If ya want easy access, take a
university.....easy targets.....lamer admins.

	5,000 system changes, such as disabling DCOM.....about 30mins of
work and I'm off to bed.....which is a good thing, cause I'm friggin'
fallin' asleep ova hea. Zzzzzzzzzzzzzzzz

	Oh, BTW...Secure your *STUFF* man.  I mean a denial of service
without even entering a password??  What kinda security does
ut-Steers-n-queers have.  I mean 129.110.8.140, 9.96, 11.30 all allow
changing the IP information and resetting the device thus causing a DoS (Not
to mention dozens of others).  I could go on and on with others, but that
wouldn't be nice.  Betcha there aren't any alarms on the IDS for that huh?
What kinda  University allows there users to use Kazaa (129.110.19.223 -
User:sinc, 15.46 - User:Butt40, 27.59 - User:kimbom, 27.149 -
User:kingfuhampster....I guess we know what the FU in kungfu really means)??
Isn't the RIAA getting up yer pooper for that?  Should you use time sync?
How can you tell when an attack acutally occured, to the second, and on
which systems.  I'm not even going to ask about 129.110.94.181.

	Be careful man, or all your holes might cause AVIEN to mean 'Another
Virus Infected Enterprise Network'

Great!  Now go click all 5000 computers we have to take care of.  This
is exactly what I'm talking about.  You smugly criticize networks for
not fixing problems, yet you completely ignore the fact that the tools
to do this on an enterprise scale either don't exist, are far too
expensive for the average network or require scripting expertise that
most don't have.  Not to mention the fact that for this to even work,
the security context must be administrator and the concept of sudo
hasn't entered the Windows world in a secure implementation (that I'm
aware of).

No, but we don't charge them an arm and leg either.  Like most
universities, the product we provide is bargain priced and available to
almost anyone that's alive and breathing.

I don't think it's unreasonable to expect an operating system to come
with the tools to manage it on an enterprise level rather than having to
spend extra dollars for that functionality.  Do you?

Then don't criticize the Windows "community" for not having the tools to
do the job.  Criticize Microsoft.

You're sadly mistaken.  Unis don't expect to get everything for free. 
But they don't get enough funding to purchase a full set of commercial
tools either.  And where do you think a large chunk of the open source
stuff comes from anyway?  Who writes much of the code?  Who provides the
mirrors to the world, free of charge?  Who does most of the research?

It would be, if that were reality.  The reality is that most people's
education is highly subsidized by governments and private contributors. 
If students actually had to *pay* for their education (what it actually
costs to provide it to them) there would be far fewer students, far
fewer universities and a lot less open source programs.

Funny how you think *your* labor has value, but the IT admins' does not.

Oh, I get it.  You've never actually used an IDS.  You just understand
the dictionary definition of one.  Try sitting in front of the console
staring at a half a million alerts and see if the IDS *does* anything
besides spewing information that *you* have to research, that *you* 
have to interpret and that *you* have to take action on.
