Hi all, sorry to take up so much of your time. I switched out my NIC in the server... I think that I was having a hardware problem because I started hanging on boot up with the NIC (installed a good one and the hanging stopped). However, I tried to restart DHCP and I'm getting error messages saying that I need to specify a submask. At this point, I think I over-altered my dhcpd.conf file. Could someone possibly send me a sample dhcpd.conf? Neither my dhcpd.conf or the backup seem to be working. I'm so sorry.... I feel like an idiot with this. I'm fairly new to Linux so the learning curve is steep (fun, but steep). thanks Kristin
