accessing files

Ok the files are on an ntsf partion, on a win2k machine and until recently have been fully accessable.

I started having issues when we moved the files to another machine, but they seemed to work alright and now they can't be viewed by any of the machines or for that matter movied at all.

I think the permissions are all mixed up, i tried resetting them but that didn't work. How can these be recovered?
