DHCP running on NW 6.5 SP7.
Adresses are manually assigned. We set lease time to permanent.
WS XP SP2, Client 4.91 SP4

Restarting a client with no connection to the network and the attaching again, ipconfig shows lease time end on 1st of January 1970.

What is to be done, to have a permanent lease time even the dhcp-server is not available.
