That change shouldn't have broken anything, but I backed it out nonetheless and the connection is still not working again.

Your windows system is requesting a PPP callback...

... which your Cisco is refusing:

> *Mar  1 02:26:44.435: ppp13 LCP:    Callback 6  (0x0D0306)

... and that goes on until the Cisco has seen enough and TERMREQs the
client.

Now, why windows would request a callback on a VPDN session escapes me.
