IP Addressing Issues

I have a client of mine that is having a lot of problems accessing the
Internet. Her set up is this: D-Link cable modem/wireless router w/4 port
switch. The switch is wired to a Mac Airport for a wireless Mac and a PC
(XP) notebook and a wired desktop. They all work fine except for the
desktop. For some reason, the desktop is having problems getting an IP from
from the router. When it does get one, it is only for a brief moment and
loses it. When you try to re-aquire an IP, I get an error stating that
access is denied - IP's are all zeros. I have tried to add a Linksys
wireless USB adapter instead of CAT5 cable. That does not work. Restarting
does not work. I have tried everything. Now for the kicker. When I brought
the workstation to my shop and set it up on my wireless (Linksys 8 port
router with a Linksys G access point), the workstation works fine. I let it
run for two days without a problem and great speed. I am at a loss as to why
this is happening. The only common denominator is that AirPort. Could that
be causing a conflict somehow?

It may be that both routers have a DHCP server running on them. That can give
rise to troubles, basically there should only be one DHCP server on any given
network segment.

So would you recomend that static IP's should be used?

Yes, I would definitely give that a try, very easy to undo anyway.

Seeing that I dont know crap about Mac's and Airports, would you know how to
change the IP on the Airport? Can you access the Airport via PC?

I have the same level of knowledge as you, but this might help:
