My corporation has an SME 6.0 server, used as a file server. My users have reported that for the last few months, whenever they open an Excel 2003 spreadsheet, edit it, and then re-save it onto the server (as the same file name) they receive a "someone may have edited this file already" message, with a 'Save As' or 'Overwrite' option box. I have conducted tests and know for a fact that no other user has opened the same file. Nor is there any operation being conducted using that file.
Our workstations are XP Professional. They have been using this server for over 18 months. There are no issues with other type of files that I am aware of. I have tested on several different workstations with the same results. I have tested it as both an admin and regular access, with the same results.
The server has been rebooted several times during this period.
Any help would be appreciated.
