Your DHCP server going down would trouble me most.

Nocturnal gave you a clue last week when he asked if your DHCP client
service was disabled.
Check that this service is working properly (remember to check the
services
it depends on as well). If it fails to start in a timely manner your ip
address will become 0.0.0.0 and if the service comes on line a few
moments
later your macine will begin to look for the DHCP server asking for an
IP
address. When no response is received Client02 will give itself an
APIPA.
> Remember Client01 has the same config and does not release the IP.
TCP/IP configs may be the same, but services and other hardware may not
be
equal.
As for the question of the dhcp info remaining after reboot on Client01,
the
registry holds the answer to this please see:

If you continue to have trouble please post in:
