A network-linked computer platform configuration data access management method and system is proposed, which is designed for use with a network-linked computer platform, such as an Internet-linked Web server or the like, and which is capable of allowing a group of system administrators to browse the configuration data of each management function of the Web server at the same time while allowing only one system administrator, and not two or more, to modify the configuration data of the same management function at the same time. This feature can help prevent conflict of configuration data in the Web server that would otherwise cause abnormal operation or even system crash to the Web server.
