Re: problems publishing owa on sbs2003 with isa2000

Thank you for your reply. I have checked through all those steps. Having
read what you said it occured to me I forgot to check the router
configuration. It is apparent now, the route itself comes with some firewall
software built into it which is what is restricting the outside traffic from
getting to the sbs server.

I will sort that out today.

Thanks

Hi Andy,

Thank you for posting in SBS newsgroup.

From the description, I understand the issue to be: you can not access OWA
from internet and get 502 Proxy Error. If I have misunderstood your
concerns, please do not hesitate to let me know.

Please try to follow the detailed steps to reconfigure CEICW as following
and you can also refer to the KB 825763:

1. On the SBS 2003 Server open the Server Management console. Go to
Standard Management\To Do List.
2. Click the "Connect to the Internet" link.
3. Choose not to change the connection type and click Next. On the
Firewall
page, select "Enable firewall" and click Next.
4. On the "Services Configuration" page, select all the items and then
click Next.
5. On the "Web Services Configuration" page, make sure "Allow access to
the
entire Web site from the Internet" is selected. If you select "Allow
access
to only the following Web site services from the Internet", make sure the
web sites you want to publish are selected. Click Next.
6. On the "Web Server Certificate" page, choose to create a new Web server
certificate and then type the public FQDN of SBS.
7. Go through the remaining steps.
8. If you have a router or hardware firewall, configure it to forward
inbound traffic on TCP port 80 and 443 to the SBS server's external
address.

Also, please refer to the following KB article:

http://support.microsoft.com/?id=290113

Then, please check the OWA settings on IIS:

1. Open IIS manager and then expand Server name | Web Sites | Default Web
Site.
2. Right click Exchange and select Properties.
3. On Directory Security tab, click Edit on Authentication and access
control column.
4. Make sure only the following boxes are checked:

Basic authentication (password is sent in clear text)

5. In the "IP address and domain restrictions" section, click the Edit
button.
6. Make sure "Granted access" is selected and there are no items in the
list box.
7. Click the "Documents" tab.
8. Make sure "Enable default content page" is select and the following
items are listed in order:

Default.htm
Default.asp
index.htm
iisstart.asp
Default.aspx

If any items are missing, please add them and make them the correct order.

9. Click Start->Run, type "iisreset" (without the quotation marks) and
click OK. Then check if it works.

If it does not work, would you please help me collect the following
information?

1. Does the situation occur when you access RWW or companyweb from
internet?
2. Can you access https://FQDN/Exchange on internal clients?

| Hi,
|
| We have SBS2003 with ISA 2000 installed and I am having real difficulty
in
| publishing the owa site to external users. I have ran the internet
| connection wizard on the server which helped to configure the
certificate
| etc. I have registered a domain name on the internet and pointed the dns
A
| record for owa.domainname.co.uk and pointed it to the external ip
address
of
| which the server nic is bound.
|
| I have checked the ISA incoming web requests listener and it is
listening
on
| the correct ip address and the authentication hass been configured by
the
| wizard with the certificate with the name owa.domainname.co.uk which is
| correct.
|
| If I type the web address into the browser of a machine on the internal
| network it works but If I try to acess it from outsite it fails and
gives
an
| error Error Code: 502 Proxy Error. Connection refused(10061)
|
| I have ran this wizard several times before on other customers site and
it
| has worked fine. can anyone suggest what might be wrong this time.
|
| Regards
|
