Hello,<br />
<br />
I work in a public school district in which students have Lenovo laptops that travel from home to school. &nbsp;For some reason when students take these laptops home, then bring them back to their school they can't get connected and have to run ipconfig /flushdns and ipconfig /registerdns to get reconnected through an admin account of which they don't have as students and have to bring the laptop to an administrator. &nbsp;Is this a DNS caching issue? &nbsp;If so, can caching be turned off?

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.

Windows 10 is a personal computer operating system featuring the "universal application architecture" (UAP); apps can be designed to run across multiple devices with nearly identical code, including PCs, tablets, smartphones, embedded systems, Xbox One, Surface Hub and HoloLens. Windows 10 also includes a virtual desktop system, a window and desktop management feature called Task View, the Microsoft Edge web browser, support for fingerprint and face recognition login, voice-based search (Cortana), new security features for enterprise environments, and DirectX 12 and WDDM 2.0 to improve the operating system's graphics capabilities for games.
