    Hi all,

    Can anyone please advise how I can delete a predefined option (global) that
    I have just created? DHCP server is a windows 2003 box and I created an
    option for PXEClient but set the value as byte rather than string. I just
    want to remove this new optiion but I don't know how to.

    When I go in to delete it, (select dhcpserver\click Action menu\Set
    predetermined options\Select option 60) the delete button is disabled. The
    only way I can delete anything is if I change the OPtion class to anything
    other than 'dhcp standard options'

    Does anyone know how I can go about deleting this option as I need to reset
    it from byte to string?

    Please email me to if you can help me out with this.

    I did not find that 060 option in my list. Did you enable anything special?
    What if you just change it instead of deleting it?

    Hi there,
    I added this option. It isn't part of the default setup. I don't seem to be
    able to modify the type of field from byte to string. That's really all I
    need to do in order to get this option working via pxeboot as I want it to
    work. I'm setting up a WDS\ADS server which requires dhcp option 60 to be
    setup and pointing to the WDS\ADS server.

    So you wont find option 060 in your list if you haven't created it. I
    created it but chose byte instead of string at creation time. I'd like to
    change this to string, but it wont permit me to change it... hence I'd like
    to remove it.

    Any ideas?

    Well, you said everything now.
    If you let me know what procedure you used to create that option some ideas
    might pop-up here.

    Hi there,
    I just used the standard method of adding additional option tags to dhcp
    scopes. There is only 1 way to do it unless setting up an option tag for
    anything that is not a 'default standard option'.

    Any ideas?
