I am using Windows 2003 server as OS, is there any option to give users only Read and Write access. I don't want users to copy the file or move the file or attach the file in any mail. As the file is an very confidential. Is there any way to do so??
If you have the ability to read and write you have the ability to make a copy. In order to protect a document against unauthorized reproduction (but allow read /write access) you need to have a file format (like office file formats) that supports DRM and a DRM server. Windows Rights management service provides that functionality. You need a Windows RMS Client Access License (which you may already have depending on your CAL type) See Installing Windows Rights Management Services with Service Pack 2 Step-by-Step Guide
