PPTP VPN not working with Windows 7. Getting Error 691. RRS feed

Answers

  • Hi,

     

    Thanks for your posting.

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

    You can try these steps:

    1) Verify the logon ID and password are correct.
    2) Make sure the
    Include Windows logon domain check box is unchecked in the Options tab of the dial-up connection's Properties dialog box.
    3) Make sure the dial-up connection's security option is correctly configured to use the
    Require secured password setting.
    4) Delete all of the *.pwl files and reboot if you are using win9x.
    5) Try another logon ID or create a new Logon ID because the profile may be damaged.

  • I am getting the Error 691 when trying to VPN to a client using PPTP. The Client use the security setting CHAP and MS-CHAP v2.

    I had read the previous post "PPTP VPN not working with Windows 7. Error 691. Works fine with XP." but no solution were offered.

    The computer is Windows 7 Ultimate. I had tried ticked and unticked other boxes, stopped the firewall and still no luck.

    I ran the log (netsh ras set tr * en) and the zipped file can be found in https://cid-af62be706469eb40.office.live.com/self.aspx/.Documents/tracing.zip.

    Many thanks in advance.

    this came in from my client .... the server they are using is HP-UX gimc1 B.11.11 U 9000/800

  • I was getting error 734 with windows 7 dial up networking.  I finally found this article http://blogs.technet.com/b/rrasblog/archive/2007/04/08/troubleshooting-vista-vpn-problems.aspx that notes MS-CHAPv1 support has been removed from Vista and Win7.  After using XP with only 1 authentication protocol enabled at a time to test dial-up, I found that my dial-up server was only allowing MS-CHAPv1 and hence Vista and Win7 cannot connect.  When I try to use MS-CHAPv2 I get error 734.  If I tried PAP or CHAP, I got error 691 since those were disabled in the dial-up server.

  • We were getting the 691 error on a client. Tried several things of which none worked. Deleted and re-added the VPN and it worked... Maybe this helps

  • After eliminating all the possibilities... this worked.
