I have a file i use daily. Today I went to open it and Excel returns a
dialogue box that says:

"filename.xls cannot be accessed. The file may be read-only, or you may be
trying to access a read-only location. Or, the server the document is stored
on is not responding"

I also synchronnized this file on my other machines and they all return the
same error. I can open the file with notepad but it is text and chiberish.

Any help would be appreciated. Thanks.

Running XP SP2 and Office XP on some machines and Office 2003 on others.
