Colin Ellis is right.

The error code here E=691 is a simple authentication failure.

I hope you also changed your real password to "password", or else
you're trying to log in with password "password".



Besides that, the culprit is probably extra backslashes.  Instead of:

        name "domainname.at\\\\username"

you want:

        name "domain\\username"

with the backslash doubled instead of quadrupled.  Note that "domain"
should probably be the simple NT domain name (not a fully qualified
hostname).  Similarly, the entries in "chap-secrets" should look like:

# Secrets for authentication using CHAP
# client        server  secret                  IP addresses
domainname\\username PPTP  YourRealPassword SERVER_IP
PPTP domainname\\username  YourRealPassword SERVER_IP

with the backslashes doubled, not quadrupled.

On my PPTP tunnel, if I use double backslashes, it works.  If I
quadruple the backslashes like you've done, I get the same
authentication failure you do.
