Hi all, I have problem with ISA 3 homed-server (One to Internal, other to DMZ and External). Before, when I was installed just with 2 NIC (internal and external), User from external can reach my publish web. But, when I tried to installed NIC#3 also place publish web on DMZ, User from external can't access eventhough for ping ...then I should disable-enabled the NIC#3 everytime to solve this (intermitten). Should I put NIC #3 (interface to DMZ) for Incoming web request ? Can anybody help out with this ? Any kind of information on how to solve intermitten problem using 3 NIC Card would be helpful. I am using Basic authentication on the ISA server. Thanks Furqoni
