DHCP Server Leasing Addresses to MAC Addresses of 00-00-00-00-00-00

I'm using a Draytek DSL Modem/Router which is acting as a DHCP server.
>From this connections are made to a Linksys WRT54G and a separate
connection to Server 2003 with a dual-NIC setup for hosting XP clients.
I also have Server 2003 as a DHCP server for a specific subnet of XP
clients that are internal to the business. I also have separate
connections from the modem/router that go to a Linux box and still more
connections to external client computers. Now when I connect the
client computers I'd like the DHCP server to lease them an address but
as you can see in the following log, the server gives out every
available lease after a short amount of time. In order to clear the
active DHCP sessions I have to reboot the server; then I can lease an
address to a client computer (as you can see by the second leased
address with the Host ID. After a few hours though the list looks like
below.

Any ideas on what's going on?

Any ideas on maybe a better group to post this to?

Dunno, though it doesn't sound like a Linux problem at all, even
if it isn't clear what "Server 2003" is supposed to be?
Suggestion, use something that is known to work, like isc DHCP
server on Linux.

Good luck

It's not a Linux problem... I just use Linux primarily on my main
workstation and I failed to find a group that was specific to hardware
and router/modem issues. Server 2003 is Windows Server 2003.

Since you admit that this is not a Linux problem, and your problem
description seems to indicate that this is a problem specific to the
DCHP server running on a Microsoft Windows Server 2003, your best bet
would be to ask your question in one of the comp.os.ms-windows
newsgroups.

Here, in comp.os.LINUX.networking, we tend to discuss networking issues
with Linux, and really can't help you with what looks to be a Windows
2003 issue.

Sorry

No no no, I'll clarify that this is not an issue with Windows Server
2003. That is a separate DHCP server for only the domain clients on a
different address block and subnet. The DHCP server that is having the
problem is built into the modem/router/gateway for communicating with
the internet. I really don't know what newsgroup that would fit into...
but I'm guessing that it's running linux so this seems like a good
place!

[ Problems with above box builtin dhcp server, a Linux problem? ]

So you are guessing the above mentioned Draytek DSL Modem/Router
is running Linux and this entitles you for at least "gold"
support from this newsgroup? ;-))

However it sounds unlikely, though I'd firstly check the manual
for any hints, vendors homepage, updates which might resolve the
problem, troubleshooting guide, vendor forum for problems and
alike.

Using google for what it was intended to do would be another idea
and likely more successful then insisting on help from people
reading comp.os.linux.networking!

lol... believe me I tried searching Google first. I rarely ask a
question until I've exhausted my other resources. I've went years
without having this problem but it wasn't until recently that it
started. I thought that maybe someone would happen to know... but I
guess it's not as common as I might have thought. Not a big deal...
but would you feel better if I had just said that all the computers
hooked to the modem/router were linux and not just a few?

And the other things I suggested, it seems these days many people
start searching instead of checking the obvious first.

You still don't get it, it doesn't matter if you have +2000 M$
boxes, as long as the server runs Linux in this case dhcpd, for
the simple reason people in a LINUX newsgroup, if you know what
this is? Know how to troubleshoot problems on LINUX!

So please try the suggestions above and please stop this wild
guessing.

Hey, never meant to offend you. I always felt the the linux community
was very knowledgeable and I was simply looking for a little help.
Most people that know linux also know hardware and understand stuff
like iptables and therefore would understand a simple DHCP question.
As I told you I've searched high and low already. Wild guessing - not
sure what you mean... I just have respect for the linux community. I'm
sorry you acted this way and feel like this... thanks for cutting me
off from your vine.
