Hi, I have a client with one Plesk webserver, who wishes to expand with an additional webserver with Plesk. Both servers are going to be used for web/mail hosting. The client wishes the servers to act as nameservers for the domains being hosted at each server, with one server as primary DNS server and the other as secondary. How can this be done? Should they just both have an ACL record for the other server added, to allow zone transfers, and each domain an NS record for both servers? Thanks.
