    Is there a way to seamlessly move our DHCP from our NT4 domain to our
    Win2003 domain?
    we have trusts relationships setup between the 2.

  3. There is nothing to move unless you run a bunch of Reservations or have a
    ton of Scopes on the DHCP. Just configure the New one correctly and
    shutdown the old one,..and you are done.

    No offense, but there can be a lot to move. A single DHCP server could have
    many scopes and a whole bunch of active leases. Recreating the scopes and
    options is an exercise in drudgery and doing the whole cut the lease time
    down, wait, deactivate old, activate new, wait, up lease time, wait, now you
    are there, process is a pain.

    My specific issue with your post is that your advice will casue havoc in a
    network with users that may occasionally work from home. When they log on and
    get a new address they can could have an instant IP conflict with a client
    who believes it has a valid lease but that the new DHCP server knows nothing

    By copying the database you eliminate the all the potential lease conflict
    issues, and the drudgery of recreating the scopes. As a bonus it gets the
    task done in a few minutes.

    There is an MS utility , i beilive it is called dhcp move, or you can copy
    the dhcp database from one server to another using jetpack.

  5. That is what I said.

    ".....unless you run a bunch of Reservations or have a
    ton of Scopes on the DHCP"
    and > get a new address they can could have an instant IP conflict with a
    We've been through all that here. The actual occurances were very few and
    short lived. It certainly was not "havoc". I simply set the lease period
    on the old server to a very short period of time and waited until the new
    period had propagated to all clients. Switch the servers at a low traffic
    period, by the time it hit a high traffic period the leases had long expired
    and everything was fine. Out of our whole system I think I only had one
    conflict,..a quick "renew/release" on the two machines and all was well. The
    new server set the lease period back to what it originally was.

    I am not opposed to using the utility when it is needed, I just don't think
    people have to get all worried about it in every instance.

    In all due respect that answer is irresponsible.
    Any disruption of service that occurs that *can* be avoided yet is not is

    It is also fiscally irresponsible to use the resources or one or more admins
    to run the whole simple yet time consuming process already documented here
    when it can be done in a matter of minutes with a tool.

    Then to waste time cleaning up you mess afterward? Sure its a simple fix in
    your eyes, but to an enduser its a major pain in the tush; it makes them
    unhappy. When the users have network issues your reputation as a network
    admin takes a hit.

  7. That doesn't sound very "all due respectful".
    People usually say "with all due respect" just before they insult you. You
    are free to disagree with my post or to ignore my posts, but insulting me is
    a bit different.

    My initial string of "with all due respect" means that I am not trivializing
    your technical knowledge. You obviosly have a grasp of the mechanics.

    I never ridiculed *you*; I ridiculed your advice. I stand by my remarks.

    NOW I will ridicule you. Let it go, you are wrong. I thank the lord daily
    that I don't have reckless and pig headed techs on my team. If you ever want
    to step up and play with the big boys you need to be able to consider all
    aspects of an issue and be able to humbly accept when you are incorrect.

    You can disagree if you want, but since you are nice enough to list out all
    your impressive certs for me I can do the same. I won't post who i work for,
    but i gaurantee you probably use our equiptment.

    My apologies Todd, I was in a bad mood. I did not intend to be so abrasive. I
    am not taking back anything I said, only admitting that I may have used
    provocative language. I have no patience when it comes to pig headedness.

  11. Translation,..."I didn't do anything wrong, but now I will,..."
    I'm not the one hanging on to anything, you are.
    So you are one of the "big boys"? ...and you want me to come to you in
    humility?, you have a ring I have to kiss? Next time you are "thanking
    the Lord daily" you ought to stop and have a little longer chat with him
    Those are part of the default signature,...I didn't list them "for" you.
    The attitude makes them pretty meaningless. You're a small man
    Manny,...good thing you didn't reveal who you work for, they might loose
    business, I might stop buying from them.

    See you at the next MVP Summit,...if you'll let me humbly sit at your table.

    There's an art to disagreeing with people and I am no expert I am still
    working on it. Usually, I like to start off with, "I have another idea in
    this situation which may work....". For this scenario both your approach and
    Phil's will both work and I have done both. I think you're point needed to
    be conveyed, I don't disagree with that. There are varying degrees of
    effort which one may get hung up on oftentimes these don't get conveyed in a
    quickly-written USENET post. Even though many of us in here answering
    questions may be very good technically, we are all guilty of steam-rolling
    others when we fire off responses if we at all let emotions get in the way.
    I sent a response off to someone in here (actually at least two) which I
    wish I could take back (they know who they are). Unfortunately it's out
    there and archived in Google (the bad part about Google). The delivery was
    just a bit off, in my opinion. You certainly don't want a future employer
    "googling" you an seeing an argument between you and another person as their
    first "hit".

  13. I've never seen you do that,'re always more polite than me,...but I
    vaguely remeber the heavey use of .."dude!".. a few years ago ;-) I
    always pictured the guy in the old Dell commercials.....

    hmmm, I forget what handle I was using years ago but then I noticed someone
    else was using either the same one or something very similar so I switched
    to my real name. Also, one never gets any credit for fixes posted under
    "pseudonyms... :)

    Yes that is exactly what I meant.
    Did you defend a bad plan several times or did I? I can't remember.....
    I never said I was a big boy. I may be putting on some weight but thats
    natural when you sit at a desk most days.

    But seriously. Your remarks and advice are reminiscent of a tech resource.
    By "big boys" I meant someone who has been given the responsibility of being
    a project lead, project manager, or other bigger picture role.
    You have demonstated, in my mind, a technically adept resource who can be
    relied on to do thier assigned task. Nothing more.
    You haven't demonstrated open mindedness nor a basic understanding of the
    facts presented as they relate to the whole.
    ummmm, that was kind of my point(see referance to third period hall
    monitor). Certs and letters have specific uses. I have a pet peeve about
    people who try feel important by listing credentials on postings or in
    emails. Good advice is good advice regardless of who has posted the advice in
    a public forum.

    You still haven't admitted that maybe....just maybe, you might be wrong.
    Instead you have chosen to focus on my lack of politeness.

    I am sorry I hurt your feelings. Truly, I am not being sarcastic. And if I
    go to any conferances I will let you know so that if you are there I can buy
    you a beer and maybe we can both just chill out.
