pptpd VPN error: Can't locate module ppp-compress-18

Hail All,
I have am trying to setup a VPN server so that windows (winxp,win2k) can
connect to it exterally.
When I try to connect my winxp pro client I get the message: modprobe:
modprobe: Can't locate module ppp-compress-18
I am running redhat 9 with 2 nics and I am using iptables to do a simple
nat so that the people who connect to my vpn server (via PPTP) will then be
introduced to my internal network.
I used the files below and patched my kernel and PPP to use MPPE. I
found the ppp_mppe.o in my source directory
(/usr/src/linux-2.4.21/drivers/net/ppp_mppe.o) suggesting that it was
compiled with the kernel but I don't see it in my /lib/modules directory
(/lib/modules/2.4.20-8/kernel/drivers/net/ppp_mppe.o)
I tried to do: # insmod /usr/src/linux-2.4.21/drivers/net/ppp_mppe.o
but I get the error message:
/usr/src/linux-2.4.21/drivers/net/ppp_mppe.o: couldn't find the kernel
version the module was compiled for

ANYOne have any idea or suggestions as to what I can do?
I think the problem lies in that I don't know how to tell the kernel how
to register the module ppp_mppe.o.
I commented out the ppp_mppe line in /etc/modules.conf but I still get
that error message.

thanks for any and all help!

My config:
linux-2.4.21-openssl-0.9.6b-mppe.patch.gz
linux-2.4.21.tar.gz

ppp-2.4.1-MSCHAPv2-fix.patch.gz
ppp-2.4.1-openssl-0.9.6-mppe-patch.gz
ppp-2.4.1.tar.tar

pptpd-1.1.3-20030409.tar.gz


my problems is that I get this error in /var/log/messages:

As root get in the 2.4.21 source top directory and do "make modules_install"
and then "depmod -a".

You'll need at least pppd 2.4.2b3, found in /pub/ppp at ftp.samba.org, or
the latest CVS version - check www.samba.org for how to get that.

Or find a way to disable MS-PPC in XP. That would be better, for if
the XP is configured to request MCCP (as opposed to just the MPPE part
of MS-PPC) then the standard pppd, even a 2.4.2 version, is unable to
accept the request because of a patent on MPPC, and the PPP negotiations
will fail. If that's confusing blame MS.
