Dear All I am planning to install 2 ISA EE servers, my main aim is I need redundancy and load balancing with ISA server if one fails other should carry out all the process, Planning to configures OWA >RPC Over HTTP, publish SMTP, Secure FTP, VPN My main object is to have a redundancy in between both the ISA EE servers. Is there any way with out using third party software like RAIN.. How do I proceed for Redundancy and load balancing? Regarding the rules I have already tested on ISA standard server all works fine.
