<br>
Does your dhcp server range includes the static lease ? <o:p></o:p></p>

<p class=MsoNormal>Hello everyone.<br>
<br>
I have had a strange problem for some time with dhcpd.<br>
I have quite a bit of static leases defined in the configuration file, but<br>
once in a while, a machine will request that ip address from another MAC<br>
address and the dhcp server will acknowledge that request. This creates<br>
an IP conflict when the machine with the static lease turns on. Is there
a<br>
configuration option to fix this? Thank you<br>
<br>
Brandon<br>
