After upgrading from Office 97 to Office 2003, the links in Excel workbooks
to other workbooks are not correct anymore.
Where there used to be a link to the workbook on a network drive (for
example H:\Excel\document.xls) the link now replaces H: with C:\Documents and
Setiings\%Username%\Application Data\.......
Even after restoring the links manually, the next day on opening the
workbook, the links are not correct again.
