Is het mogelijk om een DHCP request te laten plaats vinden, waarbij je om een specifiek ip adres vraagt.
Mijn servertje is nl zijn oude lease kwijtgeraakt, maar ik zou graag nog even willen proberen een 'nieuwe lease' te krijgen met het oude ip adres.
/Edit: Os is win2k
/Edit2:
Mijn MAC adres is overigens niet veranderd.
Verder hier nog wat info die ik zelf had gevonden:

en verder:DHCP Lease Process
DHCP leases are used to reduce DHCP network traffic by giving clients specific addresses for set periods of time. The DHCP process stages can be remembered using the ROSA acronym:
Request - A broadcast is sent by the client with the client MAC address. This is a DHCP discover message with source IP address of 0.0.0.0 and destination address of 255.255.255.255. The client tries to get its last address. If it is not available, the DHCP server will send a NACK signal. The client state is initialization during the request stage.
Offer - A DHCP offer message is sent from the DHCP server with some or all the optional information as listed above. Information sent includes the IP address of the DHCP server that sent the accepted offer. All offered IP addresses are marked unavailable by the DHCP server when the DHCP server offers them until they are rejected. The client is in the selecting state during this offer stage.
Selection (or acceptance) - The first offer received by the client is accepted. The client broadcasts its selected choice using a DHCP request message which includes the IP address of the DNS server that sent the accepted offer. The client is in the requesting state during this selection stage.
Acknowledgement - The server acknowledges with a DHCP acknowledge indicating the client can use the address or it will send a DHCP Nak instructing the client that the address became unavailable. Other DHCP servers retract their offers and mark the offered address as available and the accepted address as unavailable. Any offered IP addresses not selected are freed to be used again. The client state is the binding state during this acknowledgement stage.
When the client sends the lease request, it then waits one second for an offer. If a response is not received, the request is repeated at 9, 13, and 16 second intervals with additional 0 to 1000 milliseconds of randomness. The attempt is repeated every 5 minutes thereafter. The client uses port 67 and the server uses port 68.
Client systems that are Windows 98 or later attempt to tell if another client is already using the address received from the DHCP server by pinging the address. The DHCP server can be configured to pretest addresses by pinging them, but this will increase overhead and slow server response time.
hier heb ik echter niets nuttigs kunnen vinden.DHCP backup interval
Configured in the registry at:
\hkey\local_machine\system\currentcontrolset\services\dhcp\server\parameters
DHCP files are stored in "SystemRoot\System32\Dhcp
