[pptp-server] Error 741 - The local computer does not support the required data encryption type.

[mike]

I imagine somebody else must have seen this at some point.. I installed 
PoPToP onto my Red Hat 7.1 server, and am connecting to it with a Win2K 
box.  Sans encryption, it works fine.  With encryption required by the 
Win2K box, it gives me this error: "Error 741 - The local computer does not 
support the required data encryption type."  (log activity below)

This leads me to believe that something is missing from the W2K box, so I 
was sure to upgrade to 128-bit encryption (I found the link somewhere in 
the archives).  Afterwards, it still fails.

Perhaps my pppd simply doesn't have the encryption support?  Surprisingly, 
every reference I can seem to find about patching ppp wants me to download 
the source, patch it, and build it into the kernel (no thanks) and the 
links to the patched files all seem to be dead.  Is there a place to 
download the source just for the ms-chap2 module, or a similar solution?

Any help is much appreciated.
