Hi Nathan, Might work, but I highly recommend a common switch between them (just in case). HTH, Tom www.isaserver.org/shinder Tom and Deb Shinder's Configuring ISA Server 2004 http://tinyurl.com/3xqb7 MVP -- ISA Firewalls -----Original Message----- From: nathan [mailto:ncasey@xxxxxxxxxxxxxxxxx] Sent: Tuesday, April 26, 2005 2:49 PM To: [ISAserver.org Discussion List] Subject: [isalist] 2004 Enterprise Array setup http://www.ISAserver.org I am in the process of building an ISA 2004 array to replace out current ISA 2000 array. The new array consists of two 2003 Enterprise Servers with SP1. Each server has three NIC's: One for LAN (Internal), one for DMZ (External) and one for intra-array communications. My question is regarding the NIC's for intra-array communications. Can they be connected via a crossover cable? I am using Rainwall for network load balancing.
