Unauthenticated access

The Windows Server 2003 family supports unauthenticated access, which means that user credentials (a user name and password) are not required. There are some situations where unauthenticated access is useful. This section covers:

• DNIS authorization

• ANI/CLI authentication

• Guest authentication

Important

• When you enable unauthenticated access, remote access users are connected without sending user credentials. An unauthenticated remote access client does not negotiate the use of a common authentication protocol during the connection establishment process and does not send a user name or password.

  Unauthenticated access with remote access clients could occur when the authentication protocols configured by the remote access client do not match those configured on the remote access server. In this case, the use of a common authentication protocol is not negotiated and the remote access client does not send a user name and password.
