SYMPTOMS
When a Dynamic Host Control Protocol (DHCP) client is issued an. . .0 address from a DHCP server on which the scope allows for a valid. . .0 address (even though another address may be excluded) and receives the address successfully as an active DHCP client, the DHCP client's network connectivity may not function properly. Error messages may be generated when the DHCP client, or other network resources or services, attempt to establish a network connection.

You may see the following error message when other network resources or services try to communicate across the network with the DHCP client:

Destination specified is invalid

You may see the following error message when the DHCP client attempts to establish a connection with other network resources:

Request timed out



CAUSE
Although the DHCP client receives the address from the DHCP server, the address it receives is viewed as a "network address" instead of a client address on the network. The use of the. . .0 address is disallowed as a client address even though it is a valid host address.
