Yes, it's my network, but (heheh...) that doesn't mean I know what I'm 
(I have to type out results by hand here because I have no floppy disk 
nor net connections to copy ouput from this machine to where I'm 
e-mailing now, so bear with me if I misspell or leave out something 

When I run ifconfig -a I see:
eth0   Link encap:Ethernet  HWaddr 00:15:58:18:73:C3
         inet addr: Bcast: Mask:
         inet6 addr: fe80::215::58ff:fe18:73c3/64 Scope:Link
         RX packets:39  errors:7  dropped:0 overruns:0 frame:0
         TX packets:30  errors:0  dropped: 0 overruns:0 carrier:0
(do you need the rest?  lo is running (UP LOOPBACK RUNNING) and sit0 
says NOARP, and this is hard stuff to type by hand....)

This machine is using the dreaded nVidia chipset and the eth0 card is: 
nVidia Corporation MCP51 Ethernet Controller

The Kernel is 2.6.15-1.2054_FC5 on an x86_64

/etc/sysconfig/network-scripts/ifcfg-eth0 shows:

/etc/modprobe.conf shows:
alias eth0 forcedeth
alias scsi_hostadapter sata_nv
options snd-card-0 index=0
options snd-intel8x0 index=0
remove snd-intel8x0 { /usr/sbin/alsactl store 0 > dev/null 2>&1 || : ; 
}; /sbin/modprobe -r ---ignore-remove snd-intel8x0

And the output from dhclient eth0 is:
Listening on LPF/eth0/00:15:58:18:73:c3
Sending on LPF/eth0/00:15:58:18:73:c3
Sending on Socket/fallback
DHCPDISCOVER on eth0 to port 67 interval 3
DHCPDISCOVER on eth0 to port 67 interval 6
DHCPDISCOVER on eth0 to port 67 interval 17

This is what I've seen people ask for in other messages where others 
have had similar problems. Let me know if there's something else that 
might help.
