Who is the DOS command line expert? Or is there another way to do what I need, maybe a SQL script? From inside a program I want to change permissions on a directory and all the files in it, say d:\psoft\payroll\files. The program will be running under the service account but I want to grant access to an individual user id "abcdefg". Can I use the chmod command (chmod 600 d:\psoft\payroll\files)? If so, I don't remember userid being a part of the parameter list for that command. How do I set permissions for a specific user?
