I've noticed something peculiar on my file server. I went to move some folders around and I used the "Open Files" utility in Computer Management to ensure that there were no open files in the folders I intended to use. I noticed a user who had files open that he had no reason to open (probably 20 files in the same folder)
To make a long story short, I tried opening one of those files (.xls) and it needed to be recovered because it was corrupt and it had been locked for editing by a user who hasn't worked here in almost 2 years (their account is deleted).
The user who had the files open had a session established from their workstation and that was the only session for that username. I logged onto their computer with their credentials and they had none of those files open and recent documents showed that they hadn't opened any of those documents. I ran a virus scan which came up clean and it doesn't look as though they have any malicious back doors open. I rebooted their computer and those files were no longer "open" on the file server.
I know Server 2000 is archaic (we'll be replacing it this year) but is this a known issue? Does server 2000 incorrect state which files are open? Can anyone think of another instance that would cause something like this to happen?
