[pptp-server] Win 2K/XP - mppe-40 works, mppe-128 doesn't

[R. de Vroede]

DON'T use both 40 & 128 bits! It causes weird behaviour.

Win98 works because that one allways uses 40-bits, UNLESS you install
MSDun-1.4.

More info would be nifty:
OS, versions of pptpd, ppp, kernel, Patches applied, etc.
Dump of both /etc/pptpd.conf and /etc/ppp/options(.pptp[d])

Regards,
Richard
