I have a user that needs an excel document closed. When you try to open it it will tell you that it is opened but it dosn't tell you by whom so it's read only. I'm thinking the individual who had it open has closed it since there is no name but that it's stuck in their temp files; in which case they need to reboot but we don't know who needs to reboot and we don't reboot machines on the server at night in case we need to push patches to them. I've tried copying the files to my HD and deleting them from the server but they always reappear. I tried also to take ownership and then deleting them but that does nothing to help. Does anyone have any other ideas that DO NOT include rebooting the server?
