TITLE   :XCCC:  Error Message Occurs  When You Access Logon.asp
PRODUCT :Microsoft Exchange
PROD/VER::5.5
OPER/SYS:
KEYWORDS:

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Exchange Server, version 5.5 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you try to access the Microsoft Outlook Web Access (OWA) Logon.asp page,
you may receive the following error message:

   Directory Listing Denied
   The Virtual Directory does not allow the contents to be listed.

CAUSE
=====

This issue can occur if the Default Document option has been disabled on the
default Web site. When you install OWA on a server that is running Internet
Information Server (IIS) 4.0, most settings for the default Web site are copied
to the Exchange Virtual Directory. In some cases, the Default Document option
may be disabled on the default Web site.

RESOLUTION
==========

To resolve this issue, first check the Default Document option on the default
Web site:

1. On the IIS server, click Start, click Programs, and then click "Windows NT
   4.0 Option Pack".

2. Click "Microsoft Internet Information Server", and then click Internet
   Service Manager.

3. Click to expand Default Web Site, and then click to expand
   <Server_name>, where <Server_name> is the NETBIOS name of the IIS
   server.

4. Right-click Default Web Site, and then click Properties.

5. Click the Documents tab.

6. Check to see if the "Enable Default Document" option has been enabled; if
   this option has not been enabled, you must check the same setting in the
   Exchange Virtual Directory.

Next, check the Default Document option on the Exchange Virtual Directory:

1. On the IIS server, click Start, click Programs, and then click "Windows NT
   4.0 Option Pack".

2. Click "Microsoft Internet Information Server", and then click Internet
   Service Manager.

3. Click to expand Default Web Site, and then click to expand
   <Server_name>, where <Server_name> is the NETBIOS name of the IIS
   server.

4. Click to expand Default Web Site.

5. Right-click Exchange Virtual Server, and then click Properties.

6. Click the Documents tab.

7. Check to see if the "Enable Default Document" option has been enabled; if
   this option has not been enabled, click to enable it.

8. Quit Internet Service Manager

MORE INFORMATION
================

Before you enable the Default Document option on the default Web site, make sure
there was not a valid business reason for disabling this option.
