DHCP Console Icons

The Windows? 2000 Server operating system includes the DHCP Microsoft Management Console (MMC) snap-in, an easy-to-use graphical user interface management utility that allows network administrators to define Dynamic Host Configuration Protocol (DHCP) client and server configurations. The DHCP snap-in provides context-specific icons to represent dynamically the state of member items included in the console. Member items can include DHCP servers and any clients, scopes or option types used and managed for each server.

General Usage of Console Icons

Some of the icons used in the DHCP console have specific meanings, but most icons are used to communicate general information about the current state of the management console.

	For example, when an icon is used with an hourglass superimposed on it, such as the one immediately at left, it means the console is busy attempting to connect to the managed server in order to collect data for creating or refreshing the console.
	Similarly, when an icon has a red circle with an ?X? superimposed on it, as we see in this second example, it likely means that the DHCP console has lost its connection to the DHCP server. Information explaining the issue is displayed in the console.

Usage of Specific Icons

The following is a partial listing of some icons used by the DHCP console that have specific meanings.

Server-related

Icon	Description
	DHCP server added to console.
	DHCP server connected and active in console.
	DHCP server connected but not authorized in the Active Directory^TM service for use on your network.
	DHCP server connected but the current user does not have administrative privilege to manage the server.
	DHCP server warning. Available addresses for server scopes are 90 percent or more leased and in use. This means the server is nearly out of available addresses to offer or lease to clients, and thus represents a serious or critical condition on the DHCP server.
	DHCP server alert. No addresses are available from server scopes, the maximum (that is, 100 percent) of the addresses allocated in server scopes for use are currently leased. This represents failure of the DHCP server on the network, as it is not able to lease or service any more clients.
