[pptp-server] PPP error messages

[desade-root]

Hey all....
Love this proggy....BUT...
I'm still having some probs... Wondering if anyone out there could point
me in the right directions
I've got an NT server giving DHCP over a 128 bit encrypted pipe.. No
stateless
When I run pptp I get the following error, and I cannot track it down...

Jan  3 23:17:41 localhost (unknown)[3472]:
log[pptp_dispatch_ctrl_packet:pptp_ctrl.c:637]: Outgoing call
established.
Jan  3 23:17:42 localhost pppd[3476]: The remote system (206.132.96.23)
is required to authenticate itself but I
Jan  3 23:17:42 localhost pppd[3476]: couldn't find any suitable secret
(password) for it to use to do so.

I would really love some assistance...
Thanks,
