Mac on SBS can't see Network using Proxy Server

[Richard Steele]

I've setup a Mac OSX 10.2 and Socks proxy as follows but
have no luck seeing the Internet. It can't find the
server.

Help will be greatly appreciated.

Hi Richard!

A few things...

Have you tested connectivity to the server using Ping? Open the Terminal
app from /Applications/Utilities on your Mac and enter the name or IP
address of your server. If you get a reply then good.

Also, is 1080 really the port number for accessing the web on your
server? Or is the port something else like 80 or 8080?

Also, enter this into your Mac's browser http://17.112.152.32 and see if
it takes you to Apple's website. If so, then your server proxy is
working fine but you may have problems with DNS resolving names for you.
You may need to manually enter your DNS server's IP address in your
Mac's TCP/IP preferences.

Hope this helps! bill

Is your server using the ".local" domain extension?

If so, then part of your problem may be a well known issue. See this
information on Apple's site
<http://docs.info.apple.com/article.html?artnum=107800> and this on
Microsoft's site
<http://support.microsoft.com/default.aspx?scid=kb;en-us;836413>.

You might also try hard coding the proxy server's IP address in the
Router field in the Mac's Network Settings and possibly the DNS Servers
field as well.

If you're unable to connect using the IP address I provided then you may
have a security issue instead. If you have a Windows domain, try using
"domain\userID" as your user name. For now, don't let IE remember your
password; enter it each time. And make sure you're not locking your
account with too many failed attempts.

Do your server's event logs mention anything?

Hope this helps! bill

Thanks for the continued help. Unfortunately still no
luck.

I've tried everything you suggested to no avail. I keep
getting a HTTP Error 407.
407 Proxy Authentication Required

I'm starting to believe that this is not possible.

I don't know why Microsoft says you have to use Socks
proxy to get the mac to work on a SBS 4.5 with Proxy
Server 2.0. I've tried that too, but no luck.

Any additional ideas would be appreciated. Many thanks.

Have a look at some search results I got and see if these resemble your
problem:

Also, some great SBS experts are in the
microsoft.public.windows.server.sbs newsgroup. Try posting your question
there and let's see what kind of answers you get there.

Thank you for your help. I was aware of the first one
which recommended Socks Proxy (which is not necessary),
but the second one has new information for me.

However, Philip Windel over in the Proxy Server forum

I keep getting a HTTP Error 407.
407 Proxy Authentication Required

The problem is exactly what is says. The proxy is
expecting Authentication
and you aren't giving it what it wants.

The problem is not MS or their products. The problem is
the MAC.
The MAC is only capable of Basic Authentication, which
unfortunately sends
the credentials in "plain text". You must enable Proxy2
to accept Basic
Authentication. This is done in IIS at the Default
Website on the Proxy box.
Proxys2's Web Proxy Service will use whatever type of
authentication that
IIS is set to use.

You will get a 2-line logon prompt when the browser tries
to access the
Internet. You must give it valid credentials.
