DHCP console icons reference

DHCP provides context-specific icons to dynamically represent the state of console objects. Objects include the DHCP servers, clients, scopes, and option types that are used and managed for each server.

General usage of console icons

Some of the icons used in DHCP have specific meanings, but most are used to communicate general status information about the current state of the console. For example, when an icon is used with an hourglass superimposed, such as:

DNS server forwards query to the DNS server

it means that the console is attempting to connect to the server.

Likewise, when an icon is used with a red circle and a superimposed 'X', such as:

Connection request policy logic

it often means that DHCP has lost its connection to the server.

Glossary of specific icons

The following is a partial list of console icons used in DHCP.

Option-related icons
Other console icons

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

Icon	Description
	Scope or superscope is active.
	Scope or superscope is inactive.
	Scope or superscope warning. Scope warning: 90 percent or more of the scope's IP addresses are in use. Superscope warning: If any scope within the superscope has a warning, the superscope has a warning.
	Scope or superscope alert. Scope alert: All IP addresses have been allocated by the DHCP server and are in use. No more clients can obtain IP addresses from the DHCP server because it has no more IP addresses to allocate. Superscope alert: At least one scope contained in the superscope has all IP addresses allocated by the DHCP server. No clients can obtain an IP address from the range defined in the scope that is 100 percent allocated. If other scopes within the superscope contain available addresses, the DHCP server can allocate addresses from these scopes.

Icon	Description
	Server options folder.
	Server option.
	Scope options folder.
	Scope option.
	Reservation option.
