ID: Q174779

The information in this article applies to:
-
Microsoft Internet Information Server versions 2.0, 3.0
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:
- 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.
- Once the key is complete and usable, choose Servers and click Commit
Changes Now. Exit Key Manager.
- 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.
- Restart the computer.
- Verify that the Require Secure SSL Channel option is available in the
Directories Properties page in the WWW service.
