Multihomed W2K DHCP server to Single nic

E

ejl42

We currently have a multihomed dhcp server (running DNS and WINS on i
as well) iwith three network cards.
Each card is sitting on a network segment (vlan).

Each segment contains a superscope with several subnets.

We did this because when we first migrated from NT to W2K...ip helpe
addresses didn't seem to do the trick and
this was "recommended" by Microsoft.

However, it has always been a problem on our network.

Is it possible to move our DHCP/DNS/WINS databases to a new server wit
only one nic in W2K and utilize ip helpers on our router? Someone ha
suggested setting up a WIndows2003 server..but i'm wondering if tha
would be any better?

Thanks,
Elis

You don't want Superscopes. Just use *normal* separate and distinct regular
Scopes. DHCP will give the proper address from the proper scope based on
the NIC is received the request on.

My understanding of Superscopes is that they are for exactly the opposite of
what you want. They are for taking multiple Scopes and combining them
together to behave as a single scope (as one subnet),..I personally can't
think of a valid application of such a thing, but someone appearantly has
somewhere.

You do not need any "helper" addresses on anything if the Server "lives" on
each subnet itself (via the different NICs), in fact having the helper
addresses on a router when your DHCP is multi-homed may cause problems.
You only use "helper" addresses on a Router when the DHCP is a single homed
machine.
