<div><br>Do you know, or somebody else knows, which is the DHCP client used by Windows XP?, or wheather Windows XP can handle this optional settings? what kind of modifications should we implement on the clients that they support this options if it is possible to send them though DHCP?</div>

<br>The dhcp-options man page lists all the DHCP options that the dhcp<br>server can set, but that does not mean every client will use all of<br>them.<br><br>You will need to look up the documentation for your various clients.<br>
There are only a few mandatory options that clients must implement.<br>There are a lot that are, well, optional.<br><br>Each client has an option that it sends listing the option fields that<br>it wants the dhcp server to supply. If the client does not request a<br>
particular option then the dhcp server will not send it. Even if you<br>force the server to send an option, the client may not know how to<br>decode and use the value.<br><br>regards,<br>-glenn<br>--<br>Glenn Satchell mailto:<a href="mailto:glenn.satchell@uniq.com.au">glenn.satchell@uniq.com.au</a> | Miss 9: What do you<br>
