When DNS breaks, everything breaks: sign-ins, mail, web apps and Active Directory itself. This course is about DNS on Windows Server only – how name resolution works, how to build and manage zones and records, and how to find the fault when a name does not resolve.
How the course works
Each lecture explains one idea and then shows it on Windows Server, in the DNS Manager console and in PowerShell, so you see exactly where each setting lives. The lectures are short, so you can watch one, try it on your own lab and move on.
Inside the course
- Implementing DNS: how a query is resolved, DNS components, the DNS server role, forwarders, delegation and the hosts file.
- DNS zones and records: forward and reverse lookup zones, PTR and other records, AD-integrated DNS and DNSSEC, configuring DNS clients and DHCP-based DNS settings.
- Troubleshooting: nslookup, Resolve-DnsName, the cache, logging and a step-by-step way to test a DNS server.
A practical example
A typical ticket: a user cannot reach an internal site by name, but the IP works. You check the client settings, query the server directly, look at the zone and the cache, and find the stale record – the same path the troubleshooting lectures follow.
The course runs about 6 hours in 54 lectures. It covers DNS; IP addressing, DHCP and IPv6 are not part of it. Basic Windows Server skills are enough to start.
