Thanks for your reply mindnumbed
Yup, its an NTL supplied CM (USB connected) and since theres no drivers around for it for Linux, had to splash out on an NIC card. Havent configured the card for windoze yet (only got it today so leaving USB as is for now).
No firewall set up for RH as yet, but still getting this error message (also appearing on boot up when running through set-up).
..... but if you check the config on the NiC it should be set to get an IP address dynamically by DHCP.
Yup, its set to DHCP.
