I am running a multi user program that uses an access database. The problem is that the it opens on the host computer just fine. Once I try to do anything with the file (open via the program or copy and paste) from a client it says access denied. All 3 pc's are running windows xp home. This was working just fine until this past Saturday. The folder as well as the C drive is shared. I unshared it, rebooted it then shared it again. I made sure that the check box was checked for allow users to change files. Network connectivity works fine. I am able to take control of every other file in the same folder as well. I am at a loss. PLEASE HELP!!!
