Security tab for the properties of files or folders in Windows XP Professional is the important functionality that enable administrators and users to define security permissions and rights for particular user or group to the computer resources. By default, Windows XP Professional follows recommended setting to enable the use of simple file sharing that hide the Security tab, leaving you with only General, Sharing, Web Sharing & Customize tabs as in the Simple File Sharing UI.

So to see and unhide the Security tab, just use the following steps:

1. Launch Windows Explorer or My Computer.
2. Click on the Tools at the menu bar, then click on Folder Options.
3. Click on View tab.
4. In the Advanced Settings section at the bottom of the list, uncheck and unselect (clear the tick) on the “Use simple file sharing (Recommended)” check box.
5. Click OK.

Security tab is available only to Administrator or users with administrative rights. So make sure you login as one. And security can only be set in an NTFS partition. If you’re still having problem to reveal or display the Security tab on files or folder properties, check out the following registry hack and set the value to 0 or simply delete the key:

Hive: HKEY_CURRENT_USER
Key: Software\Microsoft\windows\CurrentVersion\Policies\Explorer
Name: Nosecuritytab
Type: REG_DWORD
Value: 1

If you’re using a Windows XP Professional system that is installed in a Workgroup, the Security tab is also hidden by default because in Windows XP Home Edition and Windows XP Professional, guests are forced to log on to a workgroup. Follow the instruction and information on Microsoft Knowledge Basewhere you need to set the value for ForceGuest registry key.

Symptoms

When viewing the page in Live Page mode or when trying to view a page after publishing it to the web server, the web
browser displays any of the following errors:

• Microsoft JET Database Engine (0x80004005) Could not use ”; file already in use.
• Microsoft OLE DB Provider for ODBC Drivers error ‘80004005’ [Microsoft][ODBC Microsoft Access 97 Driver] Couldn’t use ‘(unknown)’; file already in use.
• Microsoft OLE DB Provider for ODBC Drivers (0x80004005) [Microsoft][ODBC Microsoft Access Driver] The Microsoft Jet database engine cannot open the file ‘(unknown)’. It is already opened exclusively by another user, or you need permission to view its data.
• Operation must use an updateable query. (Microsoft JET Database Engine)

Cause

This error usually happens on Windows NT, Windows 2000 or Windows XP and may be caused by any of the following conditions:
– the database file or database folder doesn’t have necessary security permissions to write to, or erase an .ldb file created by Microsoft Access when opening the database
– the database file doesn’t have sufficient security permissions or write permissions to be modified when updating data in it. The web browser is seen by the web server as a Internet User that has the server account IUSR. This user needs to have write permission to the database file and to the database folder.

Resolution

Follow these steps to resolve this issue:
1. Use Windows Explorer to find the folder on the disk, which contains the database file (.mdb). This is usually your project folder.
2. Right-click on the project folder and select Properties.
3. Uncheck the Read-only property.
4. Click on the Security tab in the properties window.
(Attention: If you don’t see such tab (Windows XP), close the properties window, open any folder, select Tools -> Folder Options -> View, and uncheck the option Use simple file sharing.)
5. Click Add and find, then select the user IUSR_<COMPUTERNAME>.
6. Select the Write checkbox in the Allow; column to assign Write permissions to the IUSR account.
