VPN to SBS2k3 from VBus

[Alan C]

I have been trying to set up a VPN connection to our SBS2k3 server from
Vista Business pc. At first I was getting error 741 and found KB929857 which
refers to this error. I used method 2.

Now when I try to connect I either get error 800 or " 'server' is not set up
to accept a connection to port 'pptp' from this computer"
No errors are logged in applics or system logs at either end.
VPN connections from my XPpro box work fine so the second error is false.

Can anyone help?

I've tried that, (and all the other options) with no success. Interestingly
since trying ms chap v2 only, I'm now just getting error 800.

I've also checked the RAS config on the server and all encryption levels are
accepted.

As there are no KB hits for VPN error 800 on Vista, I'm going demented
trying to get it to work.

I am connection through a broadband router that also has my XPpro box, which
works fine. (as noted on original post.
