Scenario 1
If the server has CHAP and MS-CHAP checked on the Security tab
and the client has Typical with Require Secure Password in drop down on
the Security tab
the VPN can be established

Scenario 2
If server has MS-CHAP and MS-CHAP2 or just MS-CHAP2 on the Security tab
and the client has Typical with Require secure Password in drop down
and Require Data Encryption checked on the Security tab
the VPN cannot be established - error 778 after Verifying username and
password

I am not 100% sure but I believe the issue started after we setup IAS
on the server because of RADIUS issues with a mica modem router.

I need to get Scenario 2 working because I want the client to be able
to just put in the IP of the server and leave the defaults which is
what Scenario 2 has.
