RE: Remote Web Workplace

Hi Vickie,

Thanks for posting here.

According to your description, I understand that the RWW does not work, and
you get "Server Application Unavailable" error message. If I am off base,
please feel free to let me know.

In order to narrow down the problem, please help to gather the following
information.

I. Can you properly access OWA, OMA, Companyweb from internal or external
network?

II. The RWW web page is a virtual directory off of the Default Web Site.
As a result, the Default Web Site must be running in order for the RWW site
to be accessible.

1. Make sure the Default Web Site is started and can be accessed. If you
cannot access the Default Web Site in a web browser, troubleshoot that
first.

Some basic things to check for if you cannot access the Default Web Site:

A. Make sure the IIS Admin Service and World Wide Web Publishing Service
are started.
B. Make sure the Default Web Site is started in the IIS MMC.
C. Make sure the Default Web Site is listening on TCP ports 80 and 443 and
the internal IP address of the SBS 2003 server.
D. Check the event logs in Event Viewer. Search the KB for any errors you
find in Event Viewer.
E. Run the CEICW. Do not select any of the 'Do Not Change' options so that
any settings will be configured.
F. Enable IIS Logging (enabled by default) and check the IIS Logs. Search
the KB for any errors you find in the log file.

2. Make sure there is a virtual directory named 'remote' underneath the
Default Web Site in the IIS MMC. Also check for the presence of the
C:\inetpub\remote folder. If they are not present, it may not be installed.
Re-install the Server Tools component using the SBS setup program.

3. Make sure your request is being redirected from http to https. You can
identify this if the URL has changed from http to https. The SBSFLT ISAPI
filter is responsible for redirecting http requests to https for certain
websites, including RWW, in SBS 2003. If this is not occurring, the SBSFLT
ISAPI filter may be down or not present.

A. In the properties of the Default Web Site, click the ISAPI Filters tab.
The SBSFLT ISAPI filter should be listed at the top of the list with a
green arrow pointing up for the Status.

SBSFLT not present: Try accessing the RWW using https instead of http in
the URL. For instance, https://www.contoso.com/remote. If this works, users
can use https in the URL to access the RWW website. If they wish to use
http, then you must click Add to add the SBSFLT ISAPI filter to the list.
The default location for the executable is C:\inetpub\sbsflt\sbsflt.dll.

SBSFLT Status shows a red arrow pointing down: Remove and re-add the SBSFLT
ISAPI filter to the Default Web Site. The default location for the
executable is C:\inetpub\sbsflt\sbsflt.dll. Also, check the Application and
System event logs for errors or warnings.

SBSFLT is not at the top of the list: Select SBSFLT and click the Move up
button to move it to the top of the list.

Please let me know the result above so that I can provide the further
assistance on this issue.

Have a nice day.

Best Regards,

Steven Zhu
