SYMPTOMS
When you perform a reconcile to synchronize the database with the registry, after deleting the DHCP database, all reservations are put back into the database but the media access control addresses are incorrect.

The DHCP server sends a NACK or does not respond to BOOTP requests from a client as the request is based on the media access control address.



CAUSE
When the BOOTP request is processed by the DHCP server, the server matches the requested media access control address in the request to an IP address and marks the reservation as in use. After performing a reconcile, the media access control address is no longer correct in the DHCP database and the client requests are either receive a NACK or the DHCP server does not respond to the BOOTP request.



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
