IIS shared configuration

Par : Surender Kumar

Since version 7, Internet Information Services (IIS) has offered a built-in feature known as IIS Shared Configuration, which uses the idea of storing the applicationHost.config, administration.config, and configEncKey.key (encryption key) files used by IIS in a network share. You can then configure multiple web servers to utilize these configuration files, and any change to the IIS configuration seamlessly propagates to other servers without any additional tool or administrative effort.
