I have been trying to block access to certain drives and I have been unsuccessful for quite some time. I have pretty much given up, however I saw a program called Fortress that effectively blocked access to selected drives. The drives were in effect "write-protected". For example, you can open a file and edit it, however when I went to save it I got different error messages in several different programs:
MS Word - Cannot save the file. 'C:\temp\doc1.doc' is not a valid file name.
Notepad - You do not have permission to open this file. (Appeared while saving!)
MS Dos Edit - Edit was unable to access the file 'C:\temp\doc1.doc'. (While windows was running.)
It's almost as if it made the hard drive read-only. However Windows has to write to certain files and it did not report any errors, so I'm not sure how Fortress accomplished this.
Can anyone offer any suggestions of how to accomplish what is described above. Note: Solution MUST work in Win 95/98.
