Configuring DNS Servers for ISA Server 2004
This document describes various ISA Server scenarios, details how to set up ISA Server for DNS for each scenario, and explains why each configuration is needed. It covers the simplest configuration, a single-homed ISA Server computer in a non-domain scenario, and also describes a complex scenario, that of a multi-homed ISA Server computer that is a domain member. Two things to remember when setting up DNS on ISA Server:
1. Only assign DNS servers to a single adapter (it doesn’t matter which one). There is no need to set up DNS on all network adapters.
2. Always point DNS to either internal servers or external servers, never to both.
