Error 737: Loopback detected

Elmar
All of a sudden, i can't connect to ASL 5 anymore over PPTP. Every clients get the 737 error. Upgraded from 5.102 to 5.2 and still no connection possible. Other solutions like stopping the PPTPd, rebooting ans starting the PPTPd didn't work.
Who can help me?

    Try to delete /var/sec/chroot-pptp/var/lock/*:
    'rm -f /var/sec/chroot-pptp/var/lock/*'

    Then restart PPTP:
    /var/mdw/scripts/pptpd restart


    This is a database which holds informations regarding loopback detection. If it is broken you might be the message "loopback detected" everytime.

    /var/sec/chroot-pptp/var/lock/ is empty. So we have to search further.

    the directory /var/sec/chroot-pptp/var/run contains the following:
    -rw-r--r--    1 root     root            5 Apr 19 07:44 ppp0.pid
    -rw-r--r--    1 root     root       401408 Apr 12 08:48 pppd.tdb
    -rw-r--r--    1 root     root            5 Apr 19 07:44 pptpd.pid

    Try to connect from another client from another location. Maybe the problem is related to the client.
    Also sometimes you get the message, if the connection is made inside the LAN. It should not show up if comming over a slow WAN connection.
