Замечания
The ServerLoginMode method allows an application to determine the login mode of a server without logging in. Login information is stored in the registry, and is accessible remotely if Windows Registry Key Permissions is set to Enumerate Subkeys.
By calling ServerLoginMode, and application may be able to reduce the amount of time necessary to determine the login mode of a server. This can be useful in a situation where the application must overcome time-out issues.
