My ReadyNAS duo has always successfully stopped 2 read/write copies of the same file being open at the same time, in just the same way as windows does - you get an option to open a read only, or to be notified, if someone else has already got the file open. Often the NAS reports that someone else has got a file open when they haven't, but you just have to select the notify option, and within 30 secs it will say that the file is now available for read/write. Annoying, but I can live with it.
However, this has suddenly changed, and on several occasions in the last week I have been able to open a read/write copy of a file that is open (as read/write) on someone else's PC. This is quite scary, because someone is going to lose their edits. It should not be possible. Does anyone out there have any clues as to why this might be possible, or if it is an indication of a general failure?
Thanks very much,
