Have you tried using the command line FTP program instead? Just call it with a script file from a .BAT file. e.g in your .bat file just change to the directory where you want to store the file then use "FTP -s:SCRIPTFILE.DAT", where SCRIPTFLE.DAT contains the FTP commands to logon to the Unix server and GET the file(s) you want.
A
VB program I currently support successfully uses this approach to get files from a Unix box on the same LAN.
