Sorry for the delay in my response. The house was hit by Lightning again (2X in 27 days, nothing before, in 6 1/2 years). Online again. :-) I will try what has been suggested here and (hopefully) report back that I solved the problem. The ADSL Modem is the DHCP server. I have an old Linksys Router/Switch working as a Switch, to share the Internet. Both are set to the OpenDNS IP addresses. This box is dual boot (WinXP and CentOS) and the DNS changes held in WinXP, so this is a matter of getting it configured properly, manually, in the config file and not with the GUI... :-) Again, my thanks for each of you, for sharing your expertise!
