Clients cannot receive any IP address
If a DHCP client does not have a configured IP address, this normally means that the client cannot set up a connection to a DHCP server. This is due either to a network problem or to the fact that the DHCP server is not available.
If the DHCP server has been started and other clients can retrieve valid addresses, check whether the client has a valid network connection and all hardware devices associated with the client (including cables and network cards) are working properly.
The DHCP server is not available
Frequently, the reason why a DHCP server does not provide the clients with address leases is because the DHCP service has not started correctly. If this is the case, the server may not have been authorized for operation in the network.
If you were previously able to start the DHCP server but it has stopped in the meanwhile, use the event display to examine the system log for entries that may explain the cause.
NOTE: To restart the DHCP service, click Start, click Run, enter cmd, and then press the <ENTER> key. Enter net start dhcpserver and then press the <ENTER> key.
