Where is that documented, if anywhere? The information I read from MS website states that the key is derived from the user credentials. It's pushed thru some permutation of MD4 and there is no mention of key regeneration. Other sources, arguably competitors, state that it does not regenerate keys. The draft itself makes NO mention of encryption, so it is even less an issue now of PPTP, but more of MS's implementation, drawing us ever further into the realm of hacks and tomfoolery MS has called cryptography.
I dont know where the perticular apropiate draft or RFC is but the reason the draft mentions no encryption is because its not it's job to do so. PPTP uses PPP's security extensions to encrypt the tunnel. You should be looking at the PPP RFC's or drafts.
