Hi. I'm running Mac OS X 10.4 Server on an old 667 MHz G4 PowerMac. For DNS, I'm using dyndns.com's free service. I've associated 2 different hostnames to my IP address (96.21.*.*) qcmat.dnsalias.net qcmat.dynalias.com My domain is from 1and1. When asked to enter my 2 name servers (they want a primary and secondary), I guess this error after a couple of hours: There is a domain registration error in the DNS. If you enter qcmat.dnsalias.net or the other one in the browser, it will open the temporary OS X Server page (I didn't change it yet). Is there something I don't understand? Thanks for the help.
