Hi all, I've got a question about installing the ISA Message filter and Message Screener. All the setup information I have seen seems to say that you need to have three machines to do this, the ISA Server to run the Message filter, your Exchange email server, and the Message screener machine. Unfortunately, I don't have a third machine to use to run the message screener. Can I still use the message screener component ? What would the setup steps be to setup this configuration if its possible ? Thanks. Nick. ____________________ Nicholas Palmer KCI Computing, Inc. (nick@xxxxxxxxxxx) 310.921.6222
