    Suddenly I have clients getting an error connecting to our PPTP VPN - error 691. Windows Server 2003. If I try to connect on the local network - no error. If their off site - error 691. Disabled security software and tried new user account - also verify user name and domain are correct - no success. Also verified PPTP port on SonicWall router is forwarded to correct IP - no luck. Please help.

    Hi Matthew,

    Error 691: Access denied because username and/or password is invalid on the domain.

    Make sure the Include Windows logon domain check box is unchecked in the Options tab of the dial-up connection's Properties dialog box.

    You can also use PortQry  port scanner utility to troubleshoot.

    I suggest you to ask here.

    It ended up being a port problem with the router on my end.
