We are going to switch to a new ip range for the company. I am using
172.xx.xx.xx today, and are going to use 10.xx.xx.xx as the new range. I
have secondary address on the router so it works with both addresses.

I have created the new scope on netware 5.1 server. I have created some
manual static clients on the new segment. Problem is that the client ask for
the old 172.xx.xx.xx address even if the mac address for the client is
configured on the new segment.

How can I prevent the workstation to ask for the "old" address and issue an
address in the new 10.xx.xx.xx segment?

Is there any way to flush the memory, and is there anyway I can put priority
on witch subnet is should search first?

Appreciate any help.
