SYMPTOMS
========

After you use Key Manager to install a new key for use with Secure Sockets Layer
(SSL) security, the option to enable SSL for a specific virtual directory or a
home directory remains unavailable (grayed out).

RESOLUTION
==========

WARNING: Using Registry Editor incorrectly can cause serious, system-wide
problems that may require you to reinstall Windows NT to correct them. Microsoft
cannot guarantee that any problems resulting from the use of Registry Editor can
be solved. Use this tool at your own risk.

The following are troubleshooting steps you can take to ensure availability of
SSL functionality:

1. Is the key complete and usable?

  In Key Manager, select the key and verify that is has been installed
  correctly. If the key has not been installed correctly or is not complete and
  usable, backup the current keyset by selecting Key, select Export Key and
  click Backup File. Select the key and delete it.

  To import the key from the original key or the backup set files, select Key,
  Import, and click Keyset Files or Backup File. Always choose Servers and
  click Commit Changes Now when you change the Key Manager configuration.

2. Once the key is complete and usable, choose Servers and click Commit Changes
  Now. Exit Key Manager.

3. The registry entry for the Sspifilt.dll file that is required for SSL
  functionality has the following location:

     Hkey_Local_Machine/System/CurrentControlSet/Services/W3svc/Parameters


  Within the Parameters key, there is a string; the value of which is comma
  delimited and should specify the path for the Sspifilt.dll file. (for
  example, C:\Winnt\System32\Inetsrv\Sspifilt.dll).

  Other Isapi filters may appear in this value as well. Verify that no spaces
  exist in this value. If spaces exist, you will need to specify a different
  physical path, without spaces, for the isapi filter dll path. (for example,
  C:\Program Files\Isapi.dll needs to change to C:\Winnt\System32\Isapi.dll or
  some valid path without spaces.

  If the Sspifilt.dll file does not exist in the registry value, add it to the
  value by double-clicking the FILTER DLLS registry value and use the String
  editor.

  NOTE: Use a comma with no spaces to separate isapi filter entries.

4. Restart the computer.

5. Verify that the Require Secure SSL Channel option is available in the
  Directories Properties page in the WWW service.
