We currently use 2 ISA 2000 Ent. servers which are load balanced with Windows 2000 NLB. The primary use is as Internet proxy. We are planning to upgrade to ISA 2004. I know that ISA 2004 std edition does not support NLB. Does ISA 2004 EE support NLB ? Can I have 2 ISA 2004 servers load balanced and act as a Internet proxy? Thanks. Raj
