Nope; if you want the whole thing, you have to run Netmon at the ISA on both 
interfaces.
No single endpoint can capture a conversation across intermediate device.

You can send to me or the list...

Jim,

Fair enough.  If I run the capture on the client, that should catch the full 
conversation, yes?  Should I enable conversations in the capture?  Also, once 
captured, do I just attach the file and send back to the list?  I know others 
have exchanged captures before but I don't recall seeing those attachments on 
the messages sent to the list.

Sorry for the silly questions.

        Only a network capture will help you determine which of the three 
entities aborted the connection.

        I created a simple server publishing rule in ISA Server 2006 that is 
configured to allow HTTPS traffic that hits the ISA Server's external IP 
address to access a server providing Secure FTP services (configured to use 
port 443, at any rate - and yes I know about 990 and 22).  However, when I 
attempt to connect, I get the following results.

        Might anyone know why the firewall is aborting the connection?



        I have a similar server publishing rule (uses FTP instead of HTTPS) 
that works.  The only difference between the two is the protocol that's allowed.



        Also, the ERROR_SUCCESS issue perplexes me because of the paradox those 
two words together present. :)
