[pptp-server] Error 650 under Windows98

[Robert Lankshear]

Greetings,

The problem I'm having is as follows:

- When connect via Ethernet to the external facing network of my Firewall /
PPTP server and connecting via PPTP under Windows98 I can connect, log-on
to the domain and work through the tunnel.

- When I connect via ISP to the Firewall / PPTP Servers I get the
Validating User dialog and then get kicked off with a 650 error message.

The log extracts are appended to the bottom.

Thanks in advance.. none of the other articles seemed to reflect this
situation.
