Exactly that's what I would have thought, but my office ISA server is
showing as closed, even though we have a published exchange server as well

If it`s bound the FW Service means that you have publshing rules for
both of them.
It should appear as open on both server if it`s published on both.

Ok guys I have run the activeports software on the remote offices ISA
server
and my own.
Basically it appears that the external IP address of each ISA server is
bound to wspsrvr.exe and this is for both ports 25 and 143
Now I would assume this is correct but it still doesn't explain why one
server is blocking portscans on 25 and 143 and the other isn't ?

You can use this tool to know what service / app is opening those ports.

Also usefull to find binding issues.
Hope it Helps

Hi,
I have an ISA server located on a remote site. Its running standard
edition
and its been setup as a web proxy, email publishing using exchange 5.5
behind the ISA.
Everything is working fine on the server, but if I do a port scan on the
system it shows SMTP and IMAP4 as open.
I have taken a look at the settings on my own offices ISA server and it
is
setup exactly the same and these two ports are closed.
Can anyone point me in the right direction of where to look as I have
checked everything out
Thanks in advance
