    I think option a) is indeed the fact. IIRC the 'new' dhcp server had
    two nics. One to the 'reg' network and one to the 'thin' network. If
    the thin clients are on their own switch along with the 'thin' nic on
    the 'new' dhcp server then I think it should work with little or no
    chance of one dhcp server interfering with the other. By deleteing the
    subnet section of the 'new' dhcp server you eliminate (I think) the
    possibility of interfering with the 'reg' network dhcp server even
    should you accidently configure it to respond on both nics.

    I can see a scenerio where that would be needed. I have the pull to try
    some things at work, as long as I don't bother the IT folks for help.
    There is resistance to anything linux. I could get permission to do a
    thin net but I wouldn't be able to change/or have changed anything on
    the company dhcp server. I would have to set it up as described. The
    dhcp server for the thin clients would also be the boot server and
    server that hosts the thin clients. Since that server is actually
    running the programs being used, it would need to be tied to the
    company network in order for the thin clients to be able to do anything
    useful at work. Thus, a dhcp server on a machine that is on a lan
    servered by another dhcp server. Sometimes we don't get to play in a
    world where we can do things as they *should* be done.
