We recently upgraded both of our ?load balanced? ISA 2000 standard servers to ISA 2004 standard. We are having an issue with our NLB setup. It seems that we can no longer use the NLB manager to manage the interfaces on both systems. The NLB that is left over from the old configuration seems to be working as it was configured, however we can?t add additional interface addresses, or make changes to our current configuration. any suggestions?
