The information in this article applies to:
- Microsoft Windows NT Server 4.0 Terminal Server Edition

This article was previously published under Q173753 SYMPTOMS
After you upgrade your Windows NT Dynamic Host Configuration Protocol
(DHCP) clients to Service Pack 2 or later, and you are using non-Windows
NT DHCP servers, you may begin receiving error messages indicating
duplicate IP addresses on your network, displayed by DHCP clients.
CAUSE
Windows NT Service Pack 2 includes an update to the DHCP client that allows
the client to send a new packet type to the DHCP server. This new packet,
DHCP DECLINE, lacks the Client ID in the DHCP Options field. Some non-
Windows NT DHCP servers may not process the DECLINE packet, which can
create duplicate IP addresses on the network.
RESOLUTIONTo 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
