I'm using APIPA on a small XP netowrk without a DHCP server. Is there a
registry setting or another way i can disable it from attempting to find a
DHCP sever before it assigns it's own address. It takes close to a minute
after it's booted up and i have to explain to each user they need to wait
longer. Also like to disable the discover messages every 3 minutes after
that since it will never find a DHCP.

Thanks

Glenn,

If you're not going to use a DHCP server, why not simply disable the client
setting "Obtain an IP address automatically ", and manually assign settings?
APIPA addresses aren't magically assigned, and doesn't have an unlimited scope;
if you have a network of any size, as it gets larger, there's always the chance
that the APIPA process may try to self assign an address that's already in use.

APIPA is intended as a workaround; if you have a computer that's setup for use
with a DHCP server, APIPA allows computers to at least get an IP address when
DHCP isn't available. I don't think it's intended for unlimited use for dynamic
address assignment, on LANs where you have no intention of using DHCP.

You can disable APIPA, but if you request DHCP assignment ("Obtain an IP address
automatically "), I don't think you can disable DHCP use. That doesn't really
make sense, if you think about it. This article tells you how to enable APIPA
manually; maybe you can do that with "Obtain an IP address automatically"
disabled.

If that solution works for you, please let us know. I don't think you're the
first person here with your question.
 
Thanks for the information Chuck. The networks are on aircrafts and there
will be multiple pilots/crew all bringing their own compters onboard. Any
pilot/crew might be on any aircraft so i would have to assign a unique IP
address to each computer. I was hoping I could use the APIPA to make less
documentation and tracking of IP address's for me.

Glenn,

That makes things a bit more interesting. I'm not sure that I would trust APIPA
for a mission critical scenario like aircraft networking. Are you setting up
ad-hoc WiFi LANs? WiFi LANs with APs? What?
