Hi

recently changed our NetWare 5.1 server to a new address. No problem for
the most part. Noticed that DHCP requests were not making it to the
server and found out the cisco core switch had an IP helper pointing to
the old server address. replaced that with the new address. Then
suddenly today we had some scanners have an issue getting IP addresses.
Went to their switch and added a ip helper to the server. that seemed to
fix it until this PM.

I am including some info from the log. I am not sure what is going on
here. The addresses that are being exchanged do not show up as used.
It looks like it loads OK and most devices are getting addresses. I am
wondering if something in the switch could be causing the issue. The
devices should be getting a 10.106.96 address.
