[pptp-server] Windows 98 / Windows 2000 Problem.

I had the same problem before.  win2k and win98 could not work at the same time.  I'm using RedHat 7.1 linux 2.4.3 pptpd 1.1.2 and pppd 2.4.1.
patch linux-2.4.4-openssl-0.9.6a-mppe.patch.gz and ppp-2.4.1-openssl-0.9.6-mppe-patch.gz

Finally following config works for all win2k(128bit)i, win98(128 and 40 bit):

vpn:/etc/ppp{65}# cat options

name *
lock
debug
mtu 1490
mru 1490
proxyarp
auth
idle 3600
+chap
#This one is optional and may be omitted.
#+chapms
+chapms-v2
ipcp-accept-local
ipcp-accept-remote
lcp-echo-failure 3
lcp-echo-interval 5
deflate 0
mppe-128
mppe-40
mppe-stateless
#nodeflate
nobsdcomp

Hopefully this help for others.
