There is a check box in the MS dialer configuration to "use remote network
as default gateway".  With it checked as you can imagine it creates a new
default route with a low metric and increments the metrics of other default
routes.

If this isn't checked many versions of the MS dialup software will insert a
classful route for the prefix of the newly installed dialup interface.  So
for your example lets say your PPTP tunnel is addressed with 192.168.1.100,
then the MS dialup software has frequently installed a 192.168.0.0/16 route.
If you are lucky enough to have your internal sites fall within one classful
boundary then you could lean on this behavior to build a "split-tunnel".
YMMV as I doubt microsoft is committed to keeping this quirk and I can't
recall which of their clients behaved which ways, just that this behavior
has been extremely common.
