I found a couple of other DNS servers in the archive that are supposed to work with horizon: cns1.idirect.com cns2.idirect.com
the horizon interface accepts these... but it accepts anything.. and it did not used to. Not only does it accept anything, but whois [EMAIL PROTECTED] gives ns1.domaindirect.com and ns2.domaindirect.com as the DNS servers on the domains I register through horizon... This behavior is exactly the same as we are seeing through the production interface: name servers are not being set.
