I'm copying a complete website into a specific location and I'm triying to give rights to everyone(LOCAL) to every folder in it because the user can download and make the server create files and folders, I'm using Win32_UserAccount and Win32_Account but for most users I'm getting the following error(Including aspnet which I think is the most important):

System.Security.Principal.IdentityNotMappedException: Some or all identity references could not be translated.
   at System.Security.Principal.NTAccount.Translate(IdentityReferenceCollection sourceAccounts, Type targetType, Boolean forceSuccess)
   at System.Security.Principal.NTAccount.Translate(Type targetType)
   at System.Security.AccessControl.CommonObjectSecurity.ModifyAccess(AccessControlModification modification, AccessRule rule, Boolean& modified)
   at System.Security.AccessControl.CommonObjectSecurity.AddAccessRule(AccessRule rule)
   at System.Security.AccessControl.FileSystemSecurity.AddAccessRule(FileSystemAccessRule rule)
   at


Check out my code below for more information.


SelectQuery sQuery = new SelectQuery("Win32_UserAccount", "Domain<>'"
                                     + System.Environment.UserDomainName.ToString() + "'");
                ManagementObjectSearcher mSearcher = new ManagementObjectSearcher(sQuery);
                foreach (ManagementObject mObject in mSearcher.Get())
                {
                        DirectorySecurity myDirectorySecurity = folder.GetAccessControl();
                        string User = System.Environment.UserDomainName + "\\" + mObject["Name"].ToString();
                                                myDirectorySecurity.AddAccessRule(new FileSystemAccessRule(User, FileSystemRights.CreateFiles, AccessControlType.Allow));
                        myDirectorySecurity.AddAccessRule(new FileSystemAccessRule(User, FileSystemRights.Modify, AccessControlType.Allow));
                        myDirectorySecurity.AddAccessRule(new FileSystemAccessRule(User, FileSystemRights.Traverse, AccessControlType.Allow));
                        myDirectorySecurity.AddAccessRule(new FileSystemAccessRule(User, FileSystemRights.ChangePermissions, AccessControlType.Allow));
                        //myDirectorySecurity.AddAccessRule(new FileSystemAccessRule(User, FileSystemRights.Modify, AccessControlType.Allow));
                        folder.SetAccessControl(myDirectorySecurity);
                                    }

you've used your domain rather than the user's domain - your line 7 above should be
string User = mObject["Domain"].ToString() + "\\" + mObject["Name"].ToString();
