I have notice that Win 2000 client (SP4) are mounting the samba share more than once. There is no problem with XP Pro or Win9x. p username mygroup 1822 Win2000client (10.1.1.1) Tue Feb 15 16:03:53 2005 p username mygroup 1822 Win2000client (10.1.1.1) Tue Feb 15 16:03:44 2005 Is there a way to change this behavior (modify register)? (when i use preexec, it runs twice two) Thansk in advance for your help.
