Unable to contact your DHCP server

[Guest]

Hello,

I get the error "unable to contact your DHCP server" when I do an ipconfig
/renew. I'll get a 169 ip address which I know is wrong. This used to work
for months and my laptop will work just fine. So it must be a problem with
my desktop. I have WinXP SP2.

The only thing I was doing was trying to add a router betwen my DSL modem
and my desktop. The router would not work. I used the installation disk
that came with the router. It just walked me through the same type of things
I would normally do via the 192.168.1.1 web site. The other thing that
happened is that I changed the password with my ISP (Verizon). But they said
that this was just for accessing mail on their web site.

So I don't know what happened.

I've installed a patch KB884020. And by the time you read this I've
probably used the WinsockFix application.

Please help - Its my Dad's PC, I'm leaving town in 2 days, and I don't want
him unable to access the internet because I tried to use a router.

Thanks in advance.

BTW - I am not using the router anymore. I'm just trying to get straight
from the DSL router to the PC. My laptop works fine - but my desktop PC does
not.

Do you mean that you are connecting the modem direct to the PC? Does the
Modem have a DHCP server? How did you share the internet before? Did you
use ICS (i.e. the PC with the internet connection had to be on for the
laptop to connect)?

Tony - I did not share the connection before. I'm switching the cable from
my dad's PC to my laptop. My laptop works - I'm writing to you now. But his
PC does not. I've tried disabling his Norton Security just in case the
Linksys install changed a permission.

All the Network Config setting look good to me.

Tony - I found the issue. Verizon only allows one MAC address to access
their network. I had apparently done the sequence of events (release on the
PC and a renew on my laptop) to change the MAC defined with Verizon. I did
not know how to change it back. I would always do a renew in conjunction
with the release on my laptop.

THis is the same reason why the router would not work - it has its own MAC.
We found the issue after I did a Clone MAC address from on the router from my
laptop.

I'm frustrated that the ISP does not have this as a part of their checklist
- they knew we had multiple computers involved.

Thanks for your assistance.
