Do you have a router ahead of your SBS? There'll be a setting in the router
configuration that refers to "GRE," "GRE47," or something like "PPTP
Pass-through." GRE47 is a protocol that needs to be enabled on the router
in order for PPTP VPN to work. (BTW, it's not a port, and opening port 47
will not help).
There's been some discussion about whether GRE47 has to be enabled at the
remote end. I can see why it would have to be, but I don't honestly know
how it's set on my home router - whatever the mfr's default. I'd try
enabling it on your end, where it for sure needs to be enabled, and if you
get the same error, try enabling it on the remote router as well.
If you're getting the message I'm thinking you're getting, it's not for sure
that problem - the message just indicates that as a possible cause. So if
you enable GRE47 and it still doesn't work, please post back with more
details of your networking configuration.

When trying to connect the remote computer just times out waiting for the
password to be verified.
On the SBS 2003, the event viewer comes up with a RASMAN error - The
connection between the VPN Server and the VPN Client has been established
but the VPN cannot be established. Event ID 20209.
It then goes on to talk about Generic Routing Encapsulation - GRE's. This
is
the point where I get confused! Not that it takes much to get me
confused....
What's the best next step please?
Thanks again for all of your help.
