I work as a helpdesk support person and I have this user who has been having problems accessing Excel 2003 files on his laptop networked to our servers. Some Excel files open up and some don't, but all of the Excel files are locally on his harddrive. The excel files are not locked, have no security and are not set to read-only. The message he gets is that Excel cannot find the file even though you can see it there in Windows Explorer. It says the file is either renamed or misspelled or not physically there in the folder.

I tried reinstalling Office 2003 and even repairing Office 2003 and still the same pop up message appears. I couldn't find anything remotely on technet.
