SYMPTOMS
Consider the following scenario:
 * You change an exclusion range on a Microsoft Windows Server 2003-based Dynamic Host Configuration Protocol (DHCP) server. Or, you disable a scope in the Microsoft Management Console (MMC) of the DHCP server.
 * A client computer that is connected to the DHCP server tries to renew its IP address by sending a DHCP request packet to the DHCP server.

In this scenario, the client computer loses network connectivity.



CAUSE
The DHCP server replies to the DHCP request packet by sending a broadcast DHCP negative acknowledgement (NAK) packet instead of by sending a unicast DHCP NAK packet. If the client computer and the DHCP server are located on different IP subnets, the broadcast DHCP NAK packet does not reach the client computer. Therefore, the client computer loses network connectivity.
