Does anyone know how to set up bind 9 so that my Windows 2k3 servers can do dynamic dns I only want my 4 servers to be able to register themselves ( and their service records ) It doesn't have to be mega secure The Windows event log says the the dns server refused the update request. There are a few howtos that show ddns with a dhcp server as the client but not static 2k3 servers. Methinks I don't understand the allow-updates and control channel properly Ta Mal
