Q184344: Reconcile on DHCP Scope Does Not Work Correctly for BOOTP Client

Product(s): Microsoft Windows NT
Version(s): WinNT:4.0,4.0a

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Server version 4.0 
- Microsoft Windows NT Server, Enterprise Edition version 4.0 
- Microsoft BackOffice Small Business Server versions 4.0, 4.0a 
- Microsoft Windows NT Server version 4.0, Terminal Server Edition 
-------------------------------------------------------------------------------

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,
please see the following article in the Microsoft Knowledge Base:
