Dynamic Update Determines if dynamic update is enabled. Computers configured for dynamic update automatically register and update their DNS resource records with a DNS server. If you enable this setting, the computers to which this setting is applied may use dynamic DNS registration on each of their network connections, depending on the configuration of each individual network connection. For a dynamic DNS registration to be enabled on a specific network connection, it is necessary and sufficient that both computer-specific and connection-specific configurations allow dynamic DNS registration. This setting controls the computer-specific property controlling dynamic DNS registration. If you enable this setting, you allow dynamic update to be set individually for each of the network connections. If you disable this setting, the computers to which this setting is applied may not use dynamic DNS registration for any of their network connections, regardless of the configuration for individual network connections. If this setting is not configured, it is not applied to any computers, and computers use their local configuration.
