Hello! The Firewall performs an essential security task on any version of Windows Server. In fact, it has the mission of preventing connections that could be attackers from accessing the server. In this way it avoids damage or loss of information. Additionally, the firewall allows you to manage the security of your computer by applying access and exit filters. Similarly, the use of rules allows or denies the traffic of information on the computer. However, for some administrative or support tasks it is necessary to deactivate it. Well, in this post we will see how to disable the firewall in Windows Server 2019/2016.
