Well, as usual, I found the solution 10 minutes after I posted :-( It's the Nokia VPN client apparently (I disabled it and it works). Now the next question is: is there any way to avoid this kind of issue? I remember in NT there used to be a feature to decide in which order things were bound etc, but I don't think there is an equivalent in W2K?
And would it actually solve the problem? The Nokia VPN client is a "miniport" one, so I guess the NPF driver would need to be a miniport driver bound before the VPN client for that to work? Any hints welcome... Thanks, Jacques.
