accessing the net via NAT (VMware)

dhclient output:

Listening on LFP/lo/
Sending on LFP/lo/

DHCPDISCOVER on lo to 255.255.255.255 port 67 interval 9
No DHCPOFFERS received
No working leases in persistent database - sleeping.

the first time running dhclient the output was somewhat different
showing my isp's ip addresses and connecting me to the net.

after shut down / reboot i ran the program again to get the linux box
online but got the above message unable to access the net through
VMware's NAT (Network Address Translation). might Zone Alarm have
anything to do with this?

BTW i also installed Slack 9 as a Guest OS and running dhclient just
tells me there are "no broadcast interfaces found - exiting".

any advice would be greatly appreciated!
