XCCC: "Directory Listing Denied" Error Message Occurs When You Access Logon.asp (296912)


The information in this article applies to:

  • Microsoft Exchange Server 5.5
This article was previously published under Q296912

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.
