summary
This article discusses the network ports and protocols used in the Microsoft Windows server system and their subcomponents.
The Windows server system includes a comprehensive, integrated infrastructure designed to meet the requirements of developers and information technology (IT) professionals. This system is designed to run specific programs and solutions, with these programs and solutions, information staff can quickly and easily access, analyze and share information. These Microsoft Server products use different network ports and protocols to communicate with the client system and other server systems via the network. Dedicated firewalls, host-based firewalls and Internet protocol security (IPSEC) filters are other important components that help ensure network security. However, if these techniques are configured to block ports and protocols used in a particular server, the server will no longer respond to client requests.
