Detailed explanation Win2003 NTFS partition can not access the problem

Friends reinstalled the Win2003 system today, found that the reinstalled NTFS partition in the system can not be accessed. I believe that many system users often encounter such problems after reinstalling the system. So what is the cause of the failure? How to solve it? Today we will analyze this problem specifically.

Failure Analysis

Is the damage caused to the D drive after the system is reinstalled? If there is a problem with the disk, the system will prompt that the disk is not ready or not formatted. Open the "Computer Management" window "Disk Management" option, found that the D drive is in good condition, and has a footprint of about 3GB, which is basically the same as the total capacity of the file. It does not appear to be a physical or logical error on the disk, and the message “Deny Access” suggested by the system also proves this.

Think carefully, after the installation of the original Windows Server 2003 system, for the convenience of work, shared the D drive, but considering the security of the file, then set the "Administrators" user group to have the D drive Full control of the permissions, and delete the default access of the D disk "Everyone" group, it seems that this situation is related to the security of the NTFS drive.

In the Explorer, right-click on the D drive and select “Properties"Open the “Local Disks (D:) Properties” dialog box and select the "Security" tab. You can see that there is an unknown user with a question mark in the window. This should be the “Administrator” user in the original Windows Server 2003 system (as shown in Figure 2). This user can access the D drive in the original system, but after installing the new system, the original user can not be recognized by the current system.

Troubleshooting

Click the “Add” button in the dialog box of Figure 2 to open the “Select User, Computer or Group” dialog box, which shows the local technical machine. All user group names in . Locate the “Administrators” group and click the “Add” button to add the admin user group to the list box below the window.

Click the "OK" button to return to the "Local Disk (D:) Properties" dialog box. You can see that the admin user group has been added to the local disk D. Select the "Full Control & Rarr; Allow" check box in the "Permissions" window to give the administrator group all rights to the D drive (as shown in Figure 3). Select the unknown user with the question mark and click the “Delete” button to remove the unknown user from the D disk's permission list.

Click the “OK" button to save the settings and the D drive will be accessible again.

Each user in the system has a unique security identifier "SID", so new users cannot access the drive or folder with the permissions set. Of course, only the drive that uses the NTFS partition on the system can set the "Security" option, which is not a problem for FAT partitioned drives.

(3) If the system is Windows XP, by default there is no "security" tab in the drive or folder properties, open the “ folder option in “Control Panel”” ; dialog box, under “Advanced Settings“ on the “View” tab, cancel the “Use Simple File Sharing (Recommended)” checkbox.
