            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 ***! 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.
