Greetings. Our computers are networked (peer to peer) and I created a
program for us to monitor our admissions but the problem is if all of us are
using the progam simultaneously we cant's make changes on ourselves (a
dialogue box shows something like "this file is being used and you don't
have exclusive access"), only the user where the file is located can make
changes. This is a networking issue, I tried Tools>Security>User and Group
permissions, and from here I don't know what to do. Anyone, please send me
the step by step procedure to do this task. Thanks in advance.
