We have a dial-up customer who is running Windows NT 4.0 and trying to
connect to our PM2E-30. The negotiation gets as far as opening the Link
Control Protocol, but then immediately fails with a "Couldn't CHAP on port
S7 - Now allowed" error. We don't have any other users using CHAP.
Is there anything extra I need to set up on the PM in order to allow CHAP?
The Configuration Guide doesn't seem to say so, but I might be missing
something. Or is there something I can have the user change on the NT end
to make it work? It doesn't seem like any communication at all is
happening after the LCP opens, but I suppose it could be something before
that point. The complete negotiation is included below (thanks to Bill
Lutton's PPP Parser!).
Thanks in advance for any help.
Kevin
