That shouldn't have any effect since ECP is not negotiated.

Possible.. though I don't know the mysteries of Windows.
I don't know why the NT machine is not responding to your request
for an IP address.. maybe it's got some configuration problem with
respect to that?
Also..
1. Try changing "set link yes chap" to "set link accept chap".
2. To enable MPPE encryption you want something like this...
set bundle enable compression
set ccp yes mppc
set ccp yes mpp-e40
set ccp yes mpp-e128
set ccp yes mpp-stateless
But the IP problem needs to be figured out first..
Can you connect to this machine using the Win95/98 PPTP dialup adapter?
