In many scenarios, a client must be able to logon to a Windows domain (e.g. MAIN-OFFICE) through a tunnel. In order for this to function, a VPN tunnel to the main office must already have been established for the domain logon to work. This is achieved with the credential provider client, which is a part of your Advanced VPN Client.
    In Windows XP the credential provider client is named GINA .

Credential provider is a dynamic-link library that is loaded with the Winlogon process at system startup. This makes it possible for a user to be authenticated at a domain controller by using user name and password.

It is imperative to install the credential provider client for domain logon to work.
