Re: ISA 2004 and Real Player

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

Now I understand about no proxy and Real Player.

The problem I'm having is that I need to authenticate my users. This is
beacuse we use Websense with ISA. Since we do website filtering by
user/group ISA needs to supply the user name to ISA (hence the requiremt for
ISA authentication). What I would like to accomplish is to selectively
bypass the requiremnt for user authentication when processing Real Player
streaming media requests. Is there any way to do this?

Again thainks for any help on this issue. ...Gary White

Well, it is not an ISA thing, it is a RealPlayer thing. Essentially, if it
has a place for "proxy settings", just leave them blank and don't use them.
(It probably has a place for proxy settings, I don't know, I never use
RealPlayer).

I'm relatively new to ISA and I'm unsure how to get Real Player to not use
the proxy. Can you explain further or point me in the right direction?

Thanks in advance. ...Gary White

I've followed your advice and implemented a dual NIC configuration.
I've
configured ISA to "let everything through" and I'm still having
problems
playing Real Player streaming video when we require the user to
authenticate
through ISA. (Note when we don't require ISA authentication Real
Player
streaming works.) I think the problem I'm having is summarized in MS
KB288734. Quoting from the article:

"This problem occurs because even though you configure Real Player 8.0
to
use HTTP proxy under Proxy settings it does not always use Web proxy
when
connecting to the Real Player Web site for channel update information.
When
this occurs, the direct HTTP request is intercepted by the HTTP
application
filter and passed on to the Web proxy service. When the Web proxy
receives
a
request from the HTTP application filter it is only allowed if
anonymous
access ("Any Request") to HTTP is permitted in the rules. If there is
no
such
rule, the request is denied."

My problem is that I don't understand how to implement either of the
two
workarounds suggested in the KB article. I would appreciate it if
someone
could explain how to implement either workaround. I would prefer not
to
use
ISA's firewall client, but will if I have to. As I see it the general
solution is to some how to selectively turn off the authentication for
selected activities (such as streaming video).

Thanks in advance for any help that you can provide.

We are trying to get Real Player to work (play videos) with ISA
2004.
When
we try to play a video we get "Connection to server could not be
established"
error messages.

Here are the system details. ISA 2004 is unihomed and configured as
a
caching server. We have a Watchguard firewall. The firewall is
only
configured to accept port 80 requests from the ISA server. Our
network's
gateway address points to the firewall. With respect to our client
configuration, we are using IE 6 and IE's proxy settings point to
our
ISA
server. The user must authenticate to use ISA and display web
pages.
(Normally these credentials are supplied transparently from the
Windows
domain login.) We do not use the ISA firewall client on our PCs.
We
are
using Real Plaer 10.0. The "Streaming Proxy" setting is set to use
"System
Settings" (i.e., IE's proxy settings). There is no provision
(unlike
Quick
Time) to save your authentication credentials (login ID/password).

I've looked at MS KB288734. I think the first part of the article
accurately discribes what is going on with RealPlayer. I'm unsure
how
to
implement "Method 1". With respect to "Method 2" I'm not sure if it
works,
becaue we use a single homed, caching server.

I've also tried to use RSTP but to no avail.

When I've bypassed ISA by going directly to the firewall, the movies
play
with no problem.

Is there a way to get this configuration to work?

Thanks in advance for any help with this problem.
