I found the fix. Even though the share to the folder was removed in the group manager the share was still open by windows. When I went to the computer manager and reviewed all the open files I saw the folder I was trying to remove was listed. So I diconnected the session and could remove the file.
We are using Dell Equlogic FS7600 NAS. Currently running firmware 3.0.911021. I am trying to removed a file using windows explorer. But as soon as I try that it gives me error: Cannot delete file: Cannot rea from the source file or disk. The file'folder must be corrupted. Since its in NAS, is there anything I can do to get rid of the file?
