Make sure that there isn't a firewall that is filtering out GRE traffic. The firewall could be on the linux box, or it could be somewhere between the PPTP server and the windows client. I had a similar problem, and it turned out that we didn't have a static mapping for GRE going through the Cisco PIX.
