WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
- Start Registry Editor (Regedt32.exe).
- Locate the following key in the registry: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/SecurityProviders/SCHANNEL/Ciphers
- Under this key, all the ciphers currently used by Schannel for secure communications are listed. Select the one you want to disable and expand the key.
- You should see a DWORD value under the key called "Enabled." Depending on the cipher you have selected, this value will either be set to "ffffffff" or "00000000" ("ffffffff" means enabled, "00000000" means disabled).
Note Be sure that you change it to reflect a hexadecimal value (this should already be the setting).
- When you set this value, restart the Web services so the change can take affect. Open a command prompt (Cmd.exe) and run Iisreset.exe to restart the Web server and its dependant services. Note that your site (and those services restarting) will be unavailable until IISRESET completes.
