BootP Client Names Disappear in DHCP Manager (167708)
The information in this article applies to:
- Microsoft Windows NT Server 4.0 Terminal Server Edition
- Microsoft Windows NT Server 4.0
This article was previously published under Q167708 SYMPTOMS
When a BOOTP client gets an IP address, the "Reservation" changes to
"Reservation in use." However, the client name is removed from the list. As
a result there is no identifier in the list to differentiate which IP
address belong to which client.
CAUSE
The DHCP server does not handle the case correctly when the BOOTP client
sends a Null host name in the DHCP Request Packet.
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

152734 How to Obtain the Latest Windows NT 4.0 Service Pack
STATUSMicrosoft has confirmed that this is a problem in Windows NT 4.0 and Windows NT Server 4.0, Terminal Server Edition. This problem was first corrected in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.
MORE INFORMATION
Normally, when an administrator has set up a reservation for a BootP client
on a Windows NT Dynamic Host Configuration Protocol (DHCP) server, the
Active Leases list includes the address, client name, and "Reservation."
When a DHCP client boots, the "Reservation" changes to "Reservation in
use."
If after applying the above-mentioned fix your DHCP Server continues to
experience the symptoms, then verify that you have configured Option 12 for
the BootP Client. When a BootP Client sends a request to the DHCP Server
and the host name is blank, the DHCP Server looks in the registry for the
HostName (Option 12) for use in propogating the Client Name field. If
Option 12 is left blank, it will leave the client name blank.
To correctly configure the BootP Client information, fill out the HostName
information in the Option 12 field of the entry. Once the Bootp request is
received, the Server will move the HostName option to the ClientName field.
