Hi Candice, Message flow: SMTP client To SMTP Server To ISA Server To SMTP Relay To Exchange Server Your setup might be different :-) HTH, Tom Thomas W Shinder www.isaserver.org/shinder ISA Server and Beyond: http://tinyurl.com/1jq1 Configuring ISA Server: http://tinyurl.com/1llp -----Original Message----- From: Candice Moore [mailto:ccm@xxxxxxxxxx] Sent: Friday, March 28, 2003 12:35 PM To: [ISAserver.org Discussion List] Subject: [isalist] Message Flow ISA, Active Directory and Exchange http://www.ISAserver.org We have put together a test bed with ISA Firewall, Exchange 2000, Active Directory and a couple of clients. We're trying to get a handle on the message flow for a better understanding of the complete picture. Can you tell me where I might find a diagram or flowchart showing message or data flow through these sytems from beginning to end, when a message is sent or received (from the internet, thru firwall, Exchange etc.)? Any help would be appreciated.
