This three-day hands on DNS training course studies both the UNIX BIND and the Microsoft (MS DNS) implementations. The course starts with the big picture of how DNS works, then client configuration. Primary and secondary servers are then configured, progressing to DDNS, subdomains and security issues. Hands on sessions follow all sections ensuring that troubleshooting techniques are used throughout the course. Students choose whether to use Windows or UNIX for the hands on sessions.
