I have a small environment with 2 servers which both handle more tasks than I would like. One of the servers has ISA 2004 with and external and internal NIC on it. It is configured as a second line of defense with the first being a cisco firewall. This server though also holds the SQL server and files. Every now and then the ISA service goes down. Doesn't happen too often but it does, and when it does it stops communications on both NICs. Is there a way to have it NOT stop communication on the internal NIC when this happens?
