SP2 Download Problem

[Doug G]

The SP2 download uses some sort of funky MS download manager and I can't get
it to work. I'm wondering if it is because I'm behind my company's firewall.
There are outbound port restrictions, so if it's using something other than
a standard HTTP port (which I suspect it is), it's not going to work without
getting IS involved and I'd rather just try it from home tonight than do
that! It's only 257Mb and will probably d/l faster over my cable modem
connection than with the shared connection from here.

Anyone else had a problem with this?

Doug,
I'm behind a pretty restrictive company firewall and I was able to download it.
I recommend that you double check that your proxy servers are configured
correctly in Control Panel->Internet Options.

The download does *not* work if you are behind a proxy-server *and* your
proxy-server required user-authentication!

Wonderful. MS is always searching for ways to make life harder.
I'm behind a company's firewall with proxy and authorisation and direct
connection to the internet is prohibited. I'm not able to change
anything in this configuration. So how can I get SP2? Isn't there a way
to download that internet user are used to? What about ftp or even a
normal http-get? Why has everything to be a little bit out of standards
if it comes from Microsoft?

I've always had the same problem with MSDN subscriber downloads, which uses
a similar (probably the same?) download manager. I had to downloaded
everything at home and burn it on CD to bring it to work.

According to our firewall's logs, the problem is that the download manager
uses the HTTP port (80) but what's coming through isn't valid HTTP.


It's no surprise that firewalls start blocking this: more and more
'call-back' backdoor trojans turn up, and to get through firewalls the
obvious solution is to connect out to standard port numbers that are open
everywhere. DNS as well as HTTP ports have been used, I've even heard of a
tunneling implementation that uses nothing but the ICMP protocol.

Just for clarity's sake: I was talking about the download manager from MSDN
Subscriber Downloads. The UI looks different, I don't know if what's
behind it is the same or not.

The problem is not because the download isnt HTTP. Its because the
downloader uses BITS which is very sensitive to proxy servers and
authentication.
You may wish to look at http://blogs.msdn.com/astebner/. Aaron has created a
version of the downloader which he is looking for testers, which may cure
the problem.

That's right, I'm experiencing also problems with MSDN subscriber
downloads. I don't understand the reason why they use such a technique
that fails in so many environments.
I guess I have also to download this at home. For heaven's sake I have a
flatline DSL there. Without it...

It's no surprise that firewalls start blocking this: more and more
'call-back' backdoor trojans turn up, and to get through firewalls the

That's my opinion too. Firewalls work right here.

Thanks!

Just read the second comment on the blog:

The solution is to use sambar (www.sambar.com); which can be configured to
work as re-proxy; and you can also set the proxy-authentication inside the
sambar-configuration.
Now if you start the sambar-server you only need to change the proxy-
settings of IE to "localhost:80" and the download works.
