Hi,

SBS 2003 that has been running for 3 years with minimal issues. I have
setup SBS and configured exchange on this machine years ago. Recently I
tried to configure an Outlook 2003 client on Winxp with all updates to
connect via RPC over HTTP with no luck.

I have about 20 of these SBS machines at other locations and have never had
an issue getting RPC over HTTP to work. I re-ran the email connection wizard
with no luck. Checked all ports on the firewall and 80 & 443 are forwarding
to the server. I can initiate a session via HTTP only which works fine.
However I can not get RPC to work. I have tried this on several machines
and it is most definitely something that is screwed up on the server. I know
for a fact that at one point this was working. I did install CRM about 2
years ago but the customer didnt want to use this after a while so I
uninstalled this. I am thinking that the CRM did something to my box but I
cannot seem to figure this out. I even tried my own laptop which I use to
test other customers machines with no luck. I am also unable to get any
windows mobile devices to connect either. It may be an issue with my
certificate, authentication is setup correctly. I checked the RPC
permissions in IIS and it is setup to use basic authentication for RPC
requests.

Any ideas? Both the server 2003 and the XP pro clients are fully patched,
office 2003 is up to SP3. I have also tried to run from a Vista client with
office 2007 and it still is failing. The windows mobile device is version 5
with activesynch.

Any help is appreciated greatly...

Ted

Hi,

I haven't got the answer to your problem but I'd strongly recommend closing
port 80 on your firewall, it is definitely not needed and only lowers your
security.

Regards Colin.

port 80 has to be open so users can get webmail, otherwise how in Gods earth
are they going to get remote mail? i havent had any issues port forwarding
this to my server it works fine, anytime a port is open it leaves a security
risk. anytime a new user is assigned an account its a security risk,
any...need i go on...

Ted as Colin says port 80 doesn't need to be open only port 443 for OWA
(webmail) and Outlook Anywhere (rpc-http) to work. Use https:// with the
cert name you setup in the CEICW.

No, port 80 does *not* need to be open. It absolutely should not be
open. It is the most attacked port there is, and opening it to your
SBS, where your AD is, borders on the foolhardy. The advice people are
giving you is borne out of experience and a good understanding of
security.

From what you have reported it is difficult to say where the issue is
rooted. It may be a certificate issue, but you haven't given enough
detailed information to conclude reliably. Here are some resources that
may help:

Ted,

As pointed out by others, port 80 does NOT need to be open, and yes, it is
FAR MORE of a risk than having SSL open. Port 80 is probably the
most-attacked port on the Internet.

Did you try Steve's suggestion to "Use https:// with the cert name you setup
in the CEICW."?

For example, if your MX record is "mail.yourdomain.com" and you have an A
record pointing that to your SBS, and you have port 443 open and forwarded
to your SBS, you should be able to have port 80 closed and use
https://mail.yourdomain.com/exchange to get to OWA.

On the LAN, can you go to https://servername/exchange and get to OWA? If
not, it will never work with SSL from the WAN side for RPC over HTTP.

Self-signed certificate or official SSL cert?

If you have a self-signed cert, re-run the CEICW and uncheck all the items
to allow via the Internet. Then re-run it, create a new web cert that
matches your MX record FQDN, and re-enable all the items you want via the
Internet.

Test it with https://mail.yourdomain.com/exchange to get to OWA.

Let us know how it goes.

Gregg Hill

Hi Gregg,

Thanks for the reply, OWA works fine from the LAN and from the Internet.
The certificate is self signed not purchased. I was thinking of running the
CEICW and unchecking everything to clear that out. I will give that a try
tonight after they leave. Sorry to all about my response I will remove 80
from my firewall port on that box and any others that arent hosting their own
site. Why is it called RPC over HTTP if HTTP is not really needed to be
open? So for RPC to work you only need 443?

Thanks again for any help

Ted,

When you say that "OWA works fine from the LAN" are you referring to
https://servername/exchange using SSL? It absolutely has to work with the
https rather than just http.

Look in IIS at your Exchweb, Exadmin, exchange-oma, and RPC sites' directory
security. They should have SSL required at 128-bit. I did nothing
manually...I just let the CEICW do it for me.

From the LAN, enter

telnet yourserverNetBIOSname 443

and make sure you get a blinking cursor. Do the same from a WAN computer to
your mail server's FQDN. If you post your mail server's FQDN, we can check
for you as well. No, it probably is not a security risk, since every spammer
and hacker on the planet is already using tools to harvest MX records, etc,
anyway.
