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..

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?
