Hello I have just one nameserver (NS1.mydomain.com) and I setup NS2.mydomain.com like a CNAME record to NS1.mydomain.com, work fine but some register don't accept my second nameserver

NetSol's nameserver registration allowed any domain to be registered, but haven't used it for a while since I just use my OpenSRS domains and create multiple domains based on them.

Remember lookups just perform name resolution first - in the end resolvers just connect to the IP address regardless of the name. So as long as you register the host as a nameserver and point it to their Ips, you shouldn't have any problems. (unless they get pissed off with that) Andy.
