A few more questions - same problem
Ice-9:
Quick update.
After trying everything I could find on the subject I did a reinstall of RH 8.
Problem is still the same, I checked /etc/resolv.conf and /etc/sysconfig/network-scripts/ifcfg-eth0 and everything seems fine.
I ran dhclient eth0 and it gives me this :
Listening on LPF/eth0/00:90:27:91:44:e4
Sending on LPF/eth0/00:90:27:91:44:e4
Sending on Socket/fallback
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 8
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 15
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 7
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 12
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 19
No DHCPOFFERS received.
No working leases in persistent database - sleeping.
Now I called my isp's helpdesk (jeez they were quick to tell me that they didn't give support for Linux) and asked a few questions, the guy told me that to the best of his knowledge it had to do with the "exchange protocols" between Win2K and RH ????
He could probably solve it easy but it was impossible by phone, I had to call in tech support from the store where I bought RH.
I don't know if it was the tone he used but I had the impression that he was bullshitting me to get rid of me asap.
Does this make any sense to anyone?
What are "exchange protocols" and what do they do, and more important can I alter something to resolve my connection problems?
Sorry to nag everyone with this again.

Well it's definitely a DHCP issue. Some incompatibility between Win2k DHCP server (I assume that is what they are using from what your tech support guys said) and the DHCP client that comes with RedHat. You might try removing the "dhclient" package and installing the older one from RedHat 7.3 called "dhcpcd" found here:
ftp://ftp.rpmfind.net/linux/redhat/7.3/en/os/i386/RedHat/RPMS/dhcpcd-1.3.22pl1-7.i386.rpm
If you would like I can try it out on my laptop first (dual booting RH8 and RH73) to make sure there is nothing more that needs to be done. I see the "ifup" script still looks for either "dhcpcd" or "pump" or "dhclient" all of which are DHCP clients. That just might be the trick to get you going.
[edit]
P.S. I just tried it on my laptop without a hitch using these steps:
# wget ftp://ftp.rpmfind.net/linux/redhat/7.3/en/os/i386/RedHat/RPMS/dhcpcd-1.3.22pl1-7.i386.rpm
# rpm -e dhclient
# rpm -Uvh dhcpcd-1.3.22pl1-7.i386.rpm
# ifdown eth0
# ifup eth0
It obtained a new lease using 7.3's DHCP client with no problem.

What is the hostname of your Linux box? What was your hostname when you used 7.3?

I called them again and their DHCP servers run under Linux.
I hade a somewhat friendlier guy on the phone this time, he looked at my logs and told me that he could see an attempt from my side to obtain an IP address which was refused "because of something that looks like a firewall or something" (his exact words)
voidmain:
Couple of things, first what does "# iptables -L" output look like (please post it if at all possible).
Second, I believe downgrading to dhcpd as I mentioned in my previous note may solve it if your firewall isn't blocking anything. I just found someone else with the same problem in bugzilla and they also said the dhcpcd does work for him:
