[pptp-server] Can connect with 128bit but need unencrypted connection first

[Christopher Tarricone]

To all,
	I have been using the archives for about three weeks and I have
found answers almost all of my questions there but I cannot find this
one... 

[ Sorry for the long post but I wanted to be as specific as possible ]

I cannot connect to the pptp server unless I have a Windows 9x client
connect with the following options NOT checked

Log on to network
Enable software compression
Require Encrypted Password
Require Data Encryption

Once the unauthenticated user is connect all of the other connect using
MSCHAP-V2 and 128bit encryption with all of the above settings on
(except software compression)

This is my options.pptp file

name LMSI
noauth
crtscts
lock
asyncmap 0
nodetach
lcp-echo-interval 45
lcp-echo-failure 4
idle 720
noipx
auth
lock
debug
+chap
+chapms
+chapms-v2
mppe-128
mppe-40
mppe-stateless
nodeflate
nobsdcomp

This is the output of the connection. You will see the Win 95 Machine
connect then the Win2k
