Hi, everybody. The scenario is as follows: 1. One ISA Server with 1 internal NIC and 1 external NIC 2. On the external NIC I have 2 IP addresses: aaa.bbb.ccc.162 - domain1 aaa.bbb.ccc.163 - domain2 Right now, I have one Exchange server published on domain2. When I try to publish the second one, for domain1, none of them is working. If I remove the domain1 mail server from published servers, everything works fine. What am I missing ? Any feedback greatly appreaciated. Regards, Alin Selicean
