Hi all, I have installed ISA in a three-homed environment; and I want to have a computer with OWA in the DMZ. This machine must access the user´s inboxes, so must be in the same organization that the inboxes´ owner, is that right?.I think that the computer in the DMZ must be in the domain of my intranet, is this OK?. So do I have to publisk the domain controller of my domain?. Thanks in advanced, Loreto. --------------------------------- Do You Yahoo!? Yahoo! Messenger!
