Setting the Authentication Level for an Application

To enable security for an application, you must set an authentication level other than None. The authentication level tells COM how much authentication protection is required, and it can range from authenticating the client at the first method call to encrypting parameter states fully. For more information on authentication levels, see RPC_C_AUTHN_LEVEL_xxx.

    To set an application's authentication level:

1. On the Applications property page in Dcomcnfg.exe, select the application and click the Properties button (or double-click the selected application).
2. On the General page, select an authentication level other than (None) from the Authentication Level list box.
3. If you will be setting other properties for this application, choose the Apply button to apply the new authentication level. Click OK if you are finished setting properties for this application and you wish to apply the changes.
