DHCP configuration question

We have a server running Windows Server 2000 that acts as our firewall and
DHCP server. When I run the "ipconfig /all" command from any client machine,
I've noticed that there is no entry for Default gateway. When I went to the
DCHP server and looked at its network card information, I noticed that there
is no default gateway information set. This machine IS the gateway. There
hasn't been any network problems reported. It's been configured this way
since it was first installed (before I got here). My question is, does DHCP
get the default gateway information from the computer it is on? And two,
should I populate this servers gateway address (it's own address) so that it
pushes it out to the DHCP clients?

Hi Jim,

No you need to set the dhcp scope options to push the Gateway address out to
clients. This can be found in the dhcp mmc console - click on scope - scope
options
- configure scope options and set '003 Router to the ip address of the
gateway' should work! when clients pick up their next lease/renew they will
get this setting

Hope this helps

A network can operate successfully without the clients having a default
gateway set if they are all on the same network segment. The default gateway
setting is required if they need to route beyond the local segment. (They
can even get out to the Internet without a dg if you are using a proxy
server).

If a machine has data to send to another machine, it checks to see if it
is in the same IP subnet. If it is, it can send the data directly using ARP
and hardware addressing. If the machine is not in the same IP subnet, it
needs to send the data to a router. This is when it needs a default gateway
(or default router) address.
