I'm setting up a reverse lookup zone for my network. <br />
<br />
Zone 10.10.in-addr.arppa<br />

DHCP Server - Watchguard 535 <br />

AD/DNS Server - Windows 2012 R2<br />
<br />
Servers and network gear using static IPs in the range of &nbsp;10.10.20/21.<br />

DHCP Pool - 10.10.21.x - 10.10.21.x /21<br />
<br />
Forward lookup zone populates fine.<br />
<br />
The reverse lookup zone works fine for all the systems in the static range or any systems in the DHCP range with that I gave a static IP. Only systems with an DHCP address fail to update. Anyone have a clue what I'm missing?

The Microsoft Server topic includes all of the legacy versions of the operating system, including the Windows NT 3.1, NT 3.5, NT 4.0 and Windows 2000 and Windows Home Server versions.

Microsoft Server OS

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.

Windows Networking

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
