Crash with shared workbook

[Pierre2004]

Hi,

I have a shared workbook on our network, about 10 users use this file. This
morning, the file crashed and the log was :"File cannot be accessed, the file
may be read only, or you may be trying to access to a read only location. Or
the server the document is stored on may not be responding". Of course the
file and the location are not read only and I have no problem on the server...

If someone can help me !!

Thanks,
