Hi, I have a question. I currently working on a project to configure two ISA 2000 server in Windows 2003 w/ Load Balancing and Fault Tolerance. ISA1 = 10.100.1.1 ISA2 = 10.100.2.1 Once I created the virtual IP (10.100.1.10) in ISA1 for load balancing. I can't ping 10.100.2.1 in ISA1. Why? Is it possible that I can make the windows OS load balancing under different network segment? Please advice, Thanks alot Ricky
