clients also have a utility that displays the client's MAC address and DHCP
|
||
|
|
lease information. To check the DHCP lease for a Windows NT and Windows 2000
|
||
|
|
client, follow these steps:</div>
|
||
|
|
<ol><li><span>Open a Command Prompt window.</span></li>
|
||
|
|
<li><span>Run <span class="uicontrol">IPCONFIG /ALL</span>.</span></li>
|
||
|
|
</ol>
|
||
|
|
<div class="section"><div class="note"><span class="notetitle">Note:</span> This utility does not dynamically update the
|
||
|
|
displayed information, so it will be necessary to rerun the utility to view
|
||
|
|
updated status. You can use the same utility with different parameters to
|
||
|
|
release and renew a lease (IPCONFIG /RELEASE and IPCONFIG /RENEW). Run IPCONFIG
|
||
|
|
/? from an MS-DOS Command Prompt to see all of the possible parameters for
|
||
|
|
the command.</div>
|
||
|
|
<p>Microsoft<sup>®</sup> Windows 2000 DHCP clients need to be
|
||
|
|
configured if you want the DHCP server to update DNS A records on behalf of
|
||
|
|
the client. You might want to delegate updates to the DHCP server if your
|
||
|
|
network has standard existing Windows clients like Windows 95
|
||
|
|
and NT, because these clients currently do not update DNS A records. This
|
||
|
|
might simplify your DNS administration because DNS updates will originate
|
||
|
|
from the DHCP server for all clients, rather than having some clients update
|
||
|
|
their own records.</p>
