    Hi Joseph and thanks for your answer,

    I'm sure that the asp working process in IIS 6 Application Pool is defined
    to run impersonating the user that the DSN belongs to (even though it is also
    defined as system DSN). Anyway I'm also sure that the user has access to the
    database and have tested it to be true.

    I also tried that with the default NETWORK SERVICE account that should have
    access to the same DSN defined in System DSN. Still getting the same error.

    So people you are (please!! LOL) welcome to come with any more ideas and
    PLEASE anyone with any experience with Liant's Relativity for RM COBOL will be
    also very helpfull cause this devil's DSN is pointing to that kind of files.
    (Why in god's name people still use COBOL!!!!)

    Thanks in advance.
