I setup a new share and file/folder permissions. I setup ntfs permissions for 3 groups with read, read/write, and modify. When testing the read/write with saving a doc from excel. The file starts to save and then says that the file already exists and do I want to over write. There are no files already there and no matter what I name it, it says that it already exists. If I add it as an admin and then try to edit it with the read/write group that has those permissions, I cannot open or rename the file, it either says the file is corrupt or that the folder is read only. Everyone in the modify group can read/write/delete correctly. Any help or direction would be appreciated.
