I have a dual 500 running OS X Server in a small business environment. All of the work files and archives are on this server and are constantly accessed by client Macs all throughout the day. Lately a problem has been occurring that when someone opens, say, an Illustrator file, and works on it, someone else can open the same file up and save changes not desired by the other. This screws up a lot of work.

Is there any way to prevent a file from being opened up by two client computers at the same time?

Generally, though, it's up to the application to detect file locks and deal with them appropriately. The server should not automatically prevent user #2 from opening the file since the application may support multiple accesses. It's up to the application to flag the file as open when user #1 accesses it, and for user #2's application to check the file status before opening (or saving) the file.

Apple Filing Protocol includes all the necessary routines for file and byte-range locking in a multi-user environment, the application just needs to use them.

In this case you need to talk to Adobe.
