I posted this somewhere else before I noticed this forum, and I deleted the initial one, sorry for the double post. Ok here's the gist: I'm doing a part-time work as a computer/network managing assistant, and I'm stumped. There are 16 computers for education, and 1 computer for the instructor. When the class students (they're learning html) write out a code, they will all put it in a shared file in the instructor's computer, and the instructor will open them one by one and review them. The thing is, the shared folder can't be allowed to more than 5 computers at once. I kept looking for ways to remedy, but to no avail. Is there a way to go around this? The ip addresses are fixed, btw. Thanks.
