Maybe you can help?
I'm running a 3Com FE574b ethernet card on a Toshiba Satellite 4100xDVD running a dual-boot NT40 and RedHat 6.1 setup (128MB RAM). The 3com card works fine with DHCP under NT networking at my work. The card also works fine with my DSL under RedHat at home (Thank you Mr.Hinds!!), but for some reason, DHCP does not seem to work on RedHat at my work (at least, according to the RedHat LinuxConf install directions at http://www.redhat.com/support/manuals/RHL-6.1-Manual/ref-guide/ch-sysconfig.html).
Here are some system messages which may be helpful. When I run netcfg in Linux and try to activate the eth0 interface, I get the error:
> Determining IP information for eth0...Operation failed. > failed.

I've searched RedHat/LinuxDoc/Linuxstart/altavista with little luck. Do I need to set a static route or tweak a parameter? I'm running out of ideas at this point.
