DHCP Lease Question

Hi, I have a 2000 server acting as a DHCP server. I have
3 questions:

1. I have set a lease time for 2 hours. I see that after
someone has disconnected from the network, though, the
address is still listed there a few hours afterwards.
Will the address stay there a while, even though I have
set the lease to 2 hours?

2. Do I need to have the DHCP CLIENT service on my server
started or should it be disabled. I have read in some
documents that it should be started and in others that it
should be stopped.

3. In my scope's properties, should I list the DNS of my
active directory server or the DNS of the lookup server I
have specified in the DNS settings of my active directory
server?

I'd appreciate any input. Thank you.

Sonny

[You mean you see it "there" in DHCP, right?]
DHCP server may recover the address after the lease
expires -- that it might not do so immediately is unsurprising
as long as there are a SURPLUS of address for requesting
clients.

Seeing it in DNS is a separate issue most of the time.

Generally yes, it cause few or no problems and is the service that
registers THAT machine dynamically. Since you are likely
referencing a DHCP server with static address it MIGHT not
be necessary though.
3. In my scope's properties, should I list the DNS of my
active directory server or the DNS of the lookup server I

I don't understand the distinction meant by "lookup server";
you should list the DNS address you wish the client to use,
your internal DNS server(s) that handle the zone supporting
their domain.

Generally that is going to be your DC if you are using AD-integrated
DNS, but can be ANY DNS server for THAT zone.
