HI David,
Welcome to SBS newsgroup.
Issue description:
=============
I understand that you encountered problem when you use one of the remote
client computer to access the Exchange 2003 via RPC over HTTP.
Analyzing and suggestions:
==============
>From your description, it should be pure client side issue, as you can
access it from home without any problem. Generally speaking, when you do it
on the intranet, the traffic will be configured as the internal traffic, so
you will be not be prompt for the user name and password. And the RPC over
HTTP connection will be available on an Internet connection:
In order to narrow down issue, please help gather more information, for
testing purpose, we suggest you connect that laptop to your SBS External
NIC then you can perform test on that laptop, please do not connect it
inside the SBS domain, the authentication is different while inside and
outside domain.
Please refer to the suggestion below for troubleshooting:
1. Have you installed ISA on your SBS 2003? Please kindly rerun CEICW to
make sure that connect outlook via internet is selected in the web services
selection page. You can refer to the KB article for more detailed
information:
825763 How to configure Internet access in Windows Small Business Server
2003
http://support.microsoft.com/?id=825763
2. On outlook side, please follow the steps below to configure it
correctly, just as I know if you connect the laptop inside domain, it will
use outlook 2003 to connect to your exchange with Lan connection, it will
not use RPC over HTTP. So please kindly refer to my suggestion below to
reconfigured to make sure that basic authentication is selected when
configure it on outlook 2003:
Access the RWW website from the laptop, you will see a instruction there:
Click "Configure Outlook via the Internet" and then the Web page "Using
Outlook via the Internet" will appear which has pretty much a step by step
list of instructions. If it tells you to use "server.domain.local", use
that. If it tells you to use "server.domain.com", use that. Follow the
steps exactly.
More info:
To do so: on the Tools menu, click E-mail Accounts. Leave the View or
change existing e-mail accounts option selected, click Next, click your
e-mail profile, and then click Change. On the Exchange Server Settings
page, click More Settings, and then click the Connection tab. Under
Exchange over the Internet, click Exchange Proxy Settings. In the Use this
authentication when connecting to my proxy server for Exchange list, click
Basic Authentication.
>From the laptop, browse to https://FQDN/rpc. In order for RPC over HTTP to
work, you must be able to browse to this URL without getting a popup
warning about the certificate. You will receive the following error on the
page:
The page cannot be displayed
HTTP Error 403.2 - Forbidden: Read access is denied.
Internet Information Services (IIS)
This is normal. The idea is to be able to get to that page without getting
the popup warning about the certificate.

Thanks for your effort on this issue, please feel free to let me know. I am
glad to be of further assistance.

| Hi;
|
| I thought I had this working, but I don't. (And the one coffee shop I
| thought it worked at, I went back to and it didn't.)
|
| This is for my daughter's laptop. It is not a domain computer (home is
| one domain, school another). Her username/password to log in to her
| laptop is identical to her username/password on the domain.
|
| I set up Outlook on her computer to always do RPC/HTTPS. At home it
| works fine - no problems, and no prompt.
|
| Trying at her school and 3 different coffee shops, I always get the
| same thing. First it pops up the IE authentication dialog asking for
| her username/password on the domain (it does not do that at home).
|
| It then gives an error 8004011D.
|
| From all 4 external locations I could go to https://server/remote and
| https://server/exchange and both worked fine, no certificate prompt,
| no authentication dialog.
|
| What should I try next?
|
| thanks - dave
