Greg said some time ago that if the ISA Box can't ping outside, it won't
be able to renew its IP address as well..

Subject: [isalist] May ISA2000 be a DHCP client as well as a server



http://www.ISAserver.org
Am running ISA 2000 standard edition as part of SBS 2000 on a w2k sp4
platform and have encountered a problem as I migrate from a Speakeasy
ADSL fixed IP connection to a DHCP dynamic IP configuration received
through TimeWarner/Earthlink from the supplied RCA cable modem. The
cable modem has model designation DCM425 and is actually manufactured by
Thompson. It appears to be functioning normally with all the expected
green lights doing what they are supposed to do. SBS2000 requires that
this server be the primary, and only, domain controller on the network
and I am beginning to suspect that the primary DC on a network may not
also be a DHCP client.  I have no issues with either connection except
that when being served by the cable modem, the server box is unable to
renew its DHCP license on expiration. At that point the Internet
connection is lost and can only be recovered through a warm boot of the
server. Server needs to be 24x7 so this is a no-go. The internal and
external NICs work normally with the noted exceptions. Anybody have an
idea what is going on?
