Actually it depends on the application. If the Windows application has the file open exclusively, then you won't be able access it from NFS. But if it is open in a mode that allows readers, it will work. And some applications open a file, copy it to a temporary file, close the original file, operate on the copy, then rename it to the original name when you do a save. And byte range locking also comes into play with some applications. All these types of lock are supported in a multi-protocol manner on the filer.

I do it every day!
It should be noted that the exact same file can't be opened at the exact same time (ie. you can't "cat" a file in unix at the exact moment MS-Word is reading the file). This is because MS-Word locks the file! So, if you find a product that WILl "cat" the file while MS-Word is using it, it sounds like they aren't implementing any locking! Ouch!
