I'm getting conflicting IP address errors, and some of our phones are
periodically unable to connect to the DHCP (NW 6.5 sp5) server to get new

Is there a way to manually flush any non-current DHCP records from
Netware? Is there a way to have it happen automatically?

DHCP is provided by 2 Netware 6.5 sp5 servers. One is the main and the
other is a backup both are on the same cluster).

We have 50 users and an availible DHCP range of 150 DHCP addresses. Those
were set to expire every 3 days.

Recently we got a VOIP phone system and those phones require DHCP
addresses as well.

I've lowered the lease to expire every 15 hours. For logistical reasons I
don't particularly want to open up a larger range.

Much thanks to any and all responses!
