I am looking to create folders for students to be able to save a copy of their work for review by the teacher. I would like them to be able to place a file in that folder but not delete or change that saved file. Additionally I would like to keep them out of each other's submission folders. I would also like to have a map to that folder.
Is there any way to do this? I have already created the folders in a shared folder and assigned the maps using group policy but every time I give them enough rights to be able to read and write to their folders, they can then delete and modify the files. Even if I specifically deny delete I still have the problem. When I give them only write access, it kinda works, but they can't actually navigate to the folder, see the contents, or map the drive. (They can copy a file to the folder and if they try it a second time they get a "folder exists error").
The clients are all windows xp with Group Policy Preference Client Side Extensions installed.
Any help or guidance would be appreciated.
