We used Macs with ISA2000, but we had to insist they use Internet
Explorer, and manually put in the proxy settings on each computer. So,
enter the host name of your ISA server and port 8080 (the default port)
into the proxy settings tab of Internet Explorer on the Macs.
If that isn't your problem, then we'll need more information from you on
what is/isn't happening.

Subject: [isalist] Instant Messenger Blocking
http://www.ISAserver.org
I wrote this last week and received a response from Dan Ball saying that
I
was on the right track with the HTTP Redirector Filter. Is there any
other way that I can approach this. My issue is still with Macintosh
clients and I am running ISA Server 2000. The following is my earlier
post:
"I am writing for a public school that is wanting to block various
instant
messengers. We are a combination PC and Macintosh environment running
one
ISA server with Web Proxy, Firewall, and Routing and Remote Access
installed. I read the article that Thomas Shinder submitted on How to
Block Dangerous Instant Messengers Using ISA Server. I am focusing
particularly on MSN Instant Messenger as it appears to be the biggest
problem. I performed the steps listed to block it, but didn't find any
success until I configured the HTTP Redirector Filter. This stopped MSN
Messenger, but presented problems with my Macintosh clients connecting
to
the Internet as apparently ISA looks at them as unauthenticated users.
When they tried to authenticate, they still couldn't. Is there
something
else I can try, or is there a particular configuration that I need to do
on the Macintosh side. PC's were fine."
Thanks,
Mark Warren
