this might not be the place for this question, i know, but i've gotten so much good advice here:

I am working off of a window computer, running windows 7 and another one running xp. Both are connected to a mac based server which holds most of my files......REcently, when i try copying certain files back from ther server to either windows machine, i get blocked with a message reading , "invalid file handle".......Is there a quick fix for this that anyone can suggest? I see that there is a way to right click the file, and unluck it via properties, but I'm dealing with hundreds of files and need to save time.
Any advice?
thank you...
