DHCP and renew and release failure

[Barry Flynn]

Hi
I've been installing a router on a cable modem to support
a friend's home network. Formerly, the cable modem was
linked to a server, which acted as the router and
allocated all the IP addresses, etc. for the four
computers (2 Apples, 2 PCs) in the house. The router is
now set up to act as a DHCP server. The two Apples
connected fine. The two PCs refused to take up new IP
addresses in the right range (192.168.0.100-199), even
after I went through the ipconfig renew release routine.
Instead, they returned an address starting 169.xx.xx.xx
with the appropriate subnet mask.
My question: how can I force the PCs to abandon their
169.xxx.xxx.xxx default IP addresses and take them from
the router instead?

Thanks

are all these computers plugged into the router, or is there a switch
between the router and the computers?

It sounds like a cabling issue, or something physical.

Yes, there is a switch in the old cabling set-up, and
it's between the router and the two PCs (significantly,
the two Apples seem to be directly connected). I had
regarded this as transparent (previous network installer
left no documentation). If that's not the case, what
should I do?

Thanks

Thanks. I did numerous reboots, but no luck. Another
reply to my post suggested a switch was the issue, which
I am pursuing.

I would try to get atleast one of the PCs direct connected to any port
on the router.
