Problem to setup DNS server on Windows Server 2016
Hello, I have problem to setup my DNS server on Windows Server 2016 Standard. But from beginning. I have installed Hyper-V 2016, on this I create Virtual Machine, and setup there Windows Server 2016. My ActiveDirectory works fine, and I want to add DNS server. I follow many tutorials on YouTube, and everyone have more folders/files in DNS Manager, on forward zone to be exactly. I have attached 2 screens: One is from YouTube where files and folders are visible. Second is from my server where I dont see this files/folders. Can I ask for help? Because I can't figure it out. I dont have ideas. I was reinstalling AD, DNS and nothing. Thank You in advance, Greetings. Jacob.
DNS duplicate record issue
Currently we are seeing duplicate DNS records for multiple DNS zones. This is specific to our VPN IP scopes, as other scopes do not appear to have this problem. In an effort to correct this issue, as it appears to be occurring from DHCP not being able to update/delete DNS records due to the client being the owner of the record, the below steps have been implemented. This is a smaller environment with approx 1200 endpoints, so the slightly more aggressive DNS intervals is not a concern. DHCP lease time adjusted to 8 days from previously 1 day DNS scavenging adjusted to "No Refresh + Refresh" = DHCP lease - 1 day 3 days (no-refresh) + 4 days (refresh) and 1 day scavenging https://docs.microsoft.com/en-us/archive/blogs/askpfe/how-dns-scavenging-and-the-dhcp-lease-duration-relate I also implemented Dynamic DNS Updates per the below MVP blog, but oddly the owner of all DNS records changed from SYSTEM as the owner to being self owned, rather than being owned by the DHCP server. https://blogs.msmvps.com/acefekay/2009/08/20/dhcp-dynamic-dns-updates-scavenging-static-entries-amp-timestamps-and-the-dnsproxyupdate-group/ The DNS duplicate issue is still occurring, which I'm assuming is due to the DHCP server not owning the DNS records and deleting them when their lease expires or updating when the IP is reassigned. Searched around quite a bit on this one and I'm stumped at this point. Anyone have an thoughts/suggestions to get DNS records to be properly owned by the DHCP server?
