I have attempted to install poptop onto a standard
redhat 7.3 box now for several days.

First I used the prebuilt packages from the site including
the custom kernel. The result each time for this was the
the xp box used as a client was able to connect but
only without encryption. I assumed that there must be a
problem with the kernel so I installed a new one and
applied the patch provided by the site. Same problem.

Finally I went back from scratch. I installed a fresh build
of redhat 7.3 upgraded compilers and openssl and
patched the kernel, downloaded the source for ppp-
2.4.1 patched it with ppp-2.4.1-openssl-0.9.6-mppe-
patch and ppp-2.4.1-MSCHAPv2-fix.patch
compiled and installed without a problem.

downloaded the stable version of the pptpd-1.1.3-
20030409 compiled and installed not a problem.

updated the modules file according to the how to install
from source code. no problem as well as the rest of the
configuration files. Once again xp provided no go with
encryption.

I have also compiled a kernel from straight source code
and applied the patches directly to this and this seems
to be no better off.

I have tried both an xp home and xp pro workstation to
connect and both suffer the same problems

There is no firewall between the servers, this is on my
LAN currently and will be until this problem is solved.
Any help would be appreciated
