My home network:
wireless router: ActionTec MI424WR
connections:
Verizon FIOS Internet
Sony VAIO desktop via ethernet - 192.168.1.5 - XP Pro
Gateway Laptop via wireless - 192.168.1.3 - Vista
Internet connection sharing works on both
file and device sharing works both ways between the 2 computers
VPN from the laptop to the desktop host gets err 800

How do I troubleshoot this?

This is over the public internet through the router to the desktop? Remember
it is *NOT* a valid test to call the desktop from the laptop over the LAN
using the public IP of the router. You can call using the private static LAN
IP in order to test basic connectivity.

When calling from a remote site make sure TCP Port 1723 is forwarded on the
router to the private static LAN IP of the desktop. Also the router needs to
be able to pass GRE Protocol 47 traffic. That is sometimes called "PPTP Pass
Through" or "VPN Pass Through" or is automatically passed when TCP Port 1723
is opened. Consult the routers users manual or manufacturers web site for
help. You can also test all of this using the test detailed in the "PPTP
Ping" and "VPN Traffic" sections on this page..

See the last part of this page for help getting the pptpsrv.exe and
pptpclnt.exe files onto your Vista machines.
