It is the ISA if the clients are set to forward HTTP requests to the
ISA.  But that's just the http part of Messenger.  In this case you'd
have to hope that the upstream firewall supports the messenger protocols
to use the full feature set of messenger.

Well, if there was an upstream doing the blocking, it's still not the
proxy ISA that's causing the issue.  This probably should be attacked
from a different angle (i.e. your upstream firewall causing the issue)

Or am I way off the mark?  On call this week and not a lot of sleep last
night......  I might be in my own little world today.....

You're assuming that there is not an upstream firewall that the ISA is
passing traffic to.  Messenger does its thing mainly over http so the
ISA
would need to be configured to allow things through (which may or may
not
happen depending on what features of Messenger are desired - see Greg's
msg
below).  Unless the ISA is bypassed, obviously, but I would assume
that's
not the desire here. 

My guess is that Greg is correct.  Ixnay on the ideovay.

If it's in Cache only mode, then there isn't a firewall to stop it from
working.  Sounds like you have another issue....  Think of ISA in this
case
as a network bridge with a hard drive....

Hi Greg,

I will test this and let you know. However I don't need voice and video,
so
here's a plus for now.

Thanks

<rant>Obviously we need to make it easier for people to find the right
information, short of running "search the web classes" because this
topic
comes up as much as anything else and the answer is always the same. 
</rant>

Get Jim's msnim.zip file and run the extracted script on your ISA. This
will
create the necessary protocols for MSN. However, since you didn't say,
I'll
assume you want to use voice and video, well here's the thing, you cant.
Messenger voice and video uses SIP which ISA as yet, doesn't support.
Until
then your toast, unless of course the person initiating the call is not
behind a NAT service, like ISA or some kind of NAT firewall. If you want
voice and video try net meeting, works well with ISA. 

Greg

Good day All

I have an ISA 2000 server that has ISA SP2 installed. The server is
setup in
Cache/Proxy mode and now I need to get MSN messenger working thru the
server. Please assist.

Many thanks
