Hi, You dont need seperate machine for Message Screener. Just 1 will do it (ISA + Smtp filter + SMTP Service + Message Screener). offcourse, for security reasons its better to have two machine: 1 for ISA + smtp filter, and 1 for Exchange + SMTP Service + Message Screener. Use the same info you've got for 3 machine, and just substitute the server name as necessary. Note on the DCOM thing, I *still* don't think it's a good idea to set allow:everyone blindly on DCOM components, including with message filters. -----Original Message----- From: Nicholas Palmer [mailto:NICK@xxxxxxxxxxx] Sent: Wednesday, April 09, 2003 4:18 AM To: [ISAserver.org Discussion List] Subject: [isalist] Installing Message Filter and Message screener with only two comp uters http://www.ISAserver.org 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.
