VPN Error 733 and Event ID 20050

I have seen quite a few posts regarding the same problem as I am
getting, however non of the solutions submitted seem to resolve it in
my case, so any assistance would be greatly appreciated.

I have a Windows SBS 2003 sat on my network with an internal address
with port 1723 NAT'ed  to our external static ip address on the router.
Likewise GRE is forwarding on the router.

I have run through the remote access wizard in order to enable VPN
access however whenever clients try to connect, the connection "seems"
to start working (Verifing Username/ Password, Registering your
computer on the network) then stops with "TCP/ IP CP reported error
733. The connection to the remote computer could not be completed. You
may need to adjust the protocols on this computer..."

I have re-run through setting up Routing and Remote Access, and have
assigned a pool of addresses for VPN connections outside of the servers
DHCP range (but on the same subnet) but this does not seem to have
fixed the problem.

In my event log I get Remote Access Error 20050, the user connected to
the porthas been disconnected because no network protocols were
sucessfully negotiated.

I have re-run through the routing and remote access and have even tried
disabling our network firewall, but still cant seem to establish a PPTP
tunnel.

Any suggestions would be greatly appreciated
