I have two ISA Server 2006 in my DMZ. My server are in a workgroup and they have 3 NIC. The first is installed how ISA SERVER storage, I'd like to join the second ISA in the array of the first ISA, for replicate all rules and have fault tollerance, but when i spin CD and make the setup on my secon server I receive the error that I need of one domain. I don't want install ADAM for security reason.
Is possible install my ISA in workgroup? Need I to install certificate?
Have any idea or any documentation?
Thanks in advance,
