Select the Enable check box to enable the PPTP Server

Select the Minimum Authentication Required . Access is denied to remote users attempting to connect using an
authentication scheme weaker than the selected scheme. The schemes are described below, from strongest to
weakest.

Encrypted Authentication (MS-CHAP v2): The strongest type of authentication to use; this is the
recommended option

Weakly Encrypted Authentication (CHAP): This is the weakest type of encrypted password authentication
to use. It is not recommended that clients connect using this as it provides very little password protection.
Also note that clients connecting using CHAP are unable to encrypt traffic

Unencrypted Authentication (PAP): This is plain text password authentication. When using this type of
authentication, the client password is transmitted unencrypted.

None
