    Did you make sure to use tftp with the "-i" option for binary mode transfer?

    Have you tried using regback to export the SAM? you should give it a try and
    see if you get any different results.

    Hi,
    I'm trying to import some SAM files into LC4, and for some reason LC4
    doesn't like the format. I get the above error for any of 5 SAM files I'm
    trying.

    For a pen test, I got these sam files by senging a 'tptp put' command to
    the SQL server (had no 'sa' password) so the SAM files were sent to my tftp
    server. There were 5 of these servers, so I got 5 SAM files to try. LC4
    doesn't like any of them.

    However, LC4 works for other SAM files... I tested with my own SAM file
    (w2k) and also another I downloaded from a machine via an http exploit...
    LC4 had no problems opening those 2 and working on them.

    Why does LC4 complain about these other SAM files? Does some other sam
    format exist or did they get mangled somehow?
    Thanks...
    Flexicon33, CISSP
