If the machine is dual-homed on different NICs and you see this outage
periodically, make sure you have network routing configured correctly
to have the gateway go through the "larger" of the dual-homed networks.
That is a classic misconfiguration of Windows Server 2003 done by many,
many people.

IIS doesn't decide to randomly go offline on one network interface but
not the other. So I believe this is a network/routing configuration
issue OUTSIDE of IIS.
