DHCP providing bad Default Gateway
I have one network port in my office. We have multiple network on that port
by using vlan tags. I switch between 2 of them periodically. Each netwrok
has a DHCP server. DHCP is provided by a Redhat Linux 4.6 server on one lan
and by a Juniper Netscreen device on the other.

A little over a week ago, this was all working fine. I would change the
vlan id on my broadcom 57xx NIC to switch networks.

However, this week, whenever I get a dhcp address from the redhat server,
there is an extra default gateway of 0.0.0.0 which prevents me from getting
anywhere.

The only change I can find that would pertain to this is a Vista Update
pertaining to DHCP (KB946456).
