We put static ip addresses in to the database mapped to a MAC address.
Whenever we make changes to the database we have to unload the dhcpsrvr
and reload it from the server to make the changes. Today we changed an ip
address from one mac address to another mac address already in the
database (machine was updated to a newer model and so the MAC address on
the NIC changed but the same IP Address was still needed) and we issues a
ipconfig /renew from windows XP but it did not update the ipaddress on the
workstation until a 'UNLOAD DHCPSRVR' and then a 'DHCPSRVR -D1' was
issued. At this point it then worked when the ipconfig was issued. Is
this normal behaviour or not?

Thanks for any help offered.
