You can try to use Windows Auditing like Scott suggests, but it's a mess and usually results with gobs of noise in the security log.
My company sells a file auditing product for Windows (and PCI) and if this is a short-term problem, you might be able to get away with just using the trial. You can get the 21 day trial here: http://www.bystorm.com/products-filesure-windows.html.
