Domain Suffix Search Order

Discussion in 'Server Networking' started by Buck Turgidson, Sep 3, 2009.

  1. We're trying to implement this on W2003 (R2 sp2) DHCP server. The option
    "135" is visible, and we've set it, but it does not seem to be taking effect
    on an XP Client.

    I've read in various places that this can only be done via a GPO.

    Has anyone gotten it to work on a DHCP server of that vintage?

    Buck,

    DHCP Option 135 is not supported by Microsoft DHCP. If I remember correctly,
    DHCP option 135 is for something else anyway such as a phone system, based
    on RFC 4578, unless it was superceded, or this one superceded a prior one
    defining such an option value. Take a look at the list of DHCP options in
    the following article, but keep in mind, Microsoft does not support all of
    them.

    You can *possibly* create the option in DHCP, but that would require some
    testing on your part.

    However, yes, you can do it in a GPO, and a lot easier. Create and link a
    GPO for this purpose. Actually you really don't want to add anything to the
    default GPOs. Take a look at the following article. You will want to alter
    the Primary DNS Suffix Devolution value. Just make sure you document it, so
    when one day comes up you don't want it anymore, you don't go crazy trying
    to figure out where's it coming from. You would be surprised that this
    question comes up once in awhile, and one of the suggestions is to check if
    they're coming from a GPO.

    You can also use DHCP Option 015, but that is the connection specific
    suffix, which only the interface that gets a config from this scope will
    apply to, meaning that if there are additional interfaces, they will not
    receive it. The GPO method applies to the machine for all interfaces.
