weird DHCP problems



Hello all.

I've been working with my RH5.2 installation for some time now,
connecting to the internet (through a cable modem) using an nic (NE2000
clone RealTek R-8029 PCI), with RedHat's automated setup for eth0 (All I
had to do is tell it to connect with DHCP, and list the DNS).

Yesterday I was configuring something in my linux, and as a result -
eth0 couldn't get the information from the dhcp server anymore. I tried
configuring many things in the system, and finally, after not being able
to get eth0 back to work, I reinstalled (!) RH5.2.

The weird thing is that even after a completly new installation, it
still doesn't aquire an IP from the dhcp server. I do know that the nic
and the driver are function correctly, because if I boot the system with
my Win98, write down the IP aquired from the dhcp, and then enter it
manually into eth0 configuration, the network operates find.

Also, when I try to run "dhcpcd -d" to aquire a new IP, I get the
following message: "bind (openSendSocket): Address already in use" (What
does it mean ?). 

In spite all that, I did manage 2-3 times to get an IP from the dhcp,
after using netconf to restart the network. I haven't been able to do it
myself, using "ifconfig eth0 down"/"ifconfig eth0 up".

(A bit long, isn't it ? But I'm working on it for 2 days, without any
success...)

Any help would be appriciated,
