Set Permissions for Shared Files and Folders

Sharing of files and folders can be managed in two ways. If you chose simplified file sharing, your folders can be shared with everyone on your network or workgroup, or you can make your folders private. (This is how folders are shared in Windows 2000.) However, in Windows XP Professional, you can also set folder permissions for specific users or groups. To do this, you must first change the default setting, which is simple file sharing.

To change this setting, follow these steps:

• Open Control Panel, click Tools, and then click Folder Options.
• Click the View tab, and scroll to the bottom of the Advanced Settings list.
• Clear the Use simple file sharing (Recommended) check box.

To manage folder permissions, browse to the folder in Windows Explorer, right–click the folder, and then click Properties. Click the Security tab, and assign permissions, such as Full Control, Modify, Read, and/or Write, to specific users.

You can set file and folder permissions only on drives formatted to use NTFS, and you must be the owner or have been granted permission to do so by the owner.

How to manually identify and remove spyware

This post provide further information about How to manually identify and remove spyware and unauthorized Browser Helper Objects in Windows XP.Spyware is a general term that is used for a program that performs certain operations, such as the following:
• Advertising
• Collecting personal information
• Changing the configuration of the computer without consent

Typically, spyware is installed together with file sharing programs and with other programs that are available for free on the Internet.

When you install a program from the Internet on a computer, make sure that you carefully read the End User License Agreement (EULA). The inclusion of unwanted software in a given software installation may be documented. However, the documentation may appear at the end of a license agreement or of a privacy statement.

Spyware programs may also be installed when you visit a Web site and are prompted to install some components before you can access the Web page. Trojan viruses and other viruses may also install spyware programs on the computer.

This post  discusses how to remove spyware that is loaded by using Browser Helper Objects (BHOs) in Microsoft Windows XP.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

You can identify a spyware program that is loaded by using BHOs. To do this, you can use the Microsoft system configuration utility (Msconfig.exe) and the Microsoft system information utility (Msinfo32.exe).

BHOs are Component Object Model (COM) components that Microsoft Internet Explorer loads whenever it starts. BHOs run in the same memory context as the browser. BHOs can perform any action on available windows and modules.

To manually remove BHOs, follow these steps:

1.  Click Start, click Run, type regedit , and then click OK.
2.  Locate and then double-click the following registry subkey:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects

3.  Under the Browser Helper Objects key, you may see ClassIDs (CLSIDs) that have a format that is similar to the following:

Note CLSIDs are 128-bit numbers in hexadecimal notation that are enclosed in a pair of braces.

4. Note the CLSID.

5. Locate and then click the following registry subkey:

HKEY_CLASSES_ROOT\CLSID\{ CLSID }\InprocServer32

Note { CLSID } is the CLSID that you noted in step 4.

6. In the right pane, double-click (Default).

7. Click Value data to see the path of the .dll file. The path may be similar to the following:

C:\Windows\ Program_Name .dll

Note Program_Name can be a spyware program or a legitimate program that is using a BHO.

8. If Program_Name is not a recognized or legitimate program, unregister the .dll file, and then remove the { CLSID } subkeys. To do this, follow these steps:

a. At a command prompt, type the following command to unregister the .dll file:

regsvr32 -u Path \ Program_Name .dll

Note Path is the path of the Program_Name .dll file that is contained in the Value data box in step 7.

b. Locate and then delete the following { CLSID } registry subkeys:

• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\CLSID\{ CLSID }

• HKEY_CLASSES_ROOT\CLSID\{ CLSID }

Note { CLSID } is the 128-bit number that you noted in step 4.

9. Exit Registry Editor.

10.Restart the computer

How to Create a boot floppy disk by using a Windows XP-based computer

This post describe how to create a bootable floppy disk.The Windows XP installation CD-ROM is a bootable disk and can be used to start Windows. When you use the Windows XP installation CD-ROM to start your computer, you can use the Windows Recovery Console to help recover the system software

Follow the steps:
1. Format a floppy disk by using the Windows XP format utility. To do this follow these steps:

1. 1. Insert the floppy disk that you want to use into the floppy disk drive.
2. 2. Click Start, click Run, type format a:, and then click OK.

2. Copy the Ntldr and the Ntdetect.com files from the I386 folder on the Windows XP installation CD-ROM, from the Windows XP installation floppy disk, or from a computer that is running the same version of Windows XP as the computer that you want to access by using the boot floppy disk.

To do this, follow these steps:

1. Insert the Windows XP installation media into the disk drive of the computer.
2. Click Start, click Run, type <DriveLetter>:\I386, and then click OK. Note<DriveLetter> represents the root location of the installation media.
3. Right-click the Ntldr file, and then click Copy.
4. Click Start, click Run, type a:, and then click OK.
5. Click the Edit menu, and then click Paste.
6. Repeat steps 2b through 2e for the Ntdetect.com file.

3. Create a Boot.ini file, or copy one from a computer that is running Windows XP, and then modify the Boot.ini file to match the computer that you are trying to access. The following example lists how to create a Boot.ini file for a single-partition Integrated Device Electronics drive that has Windows XP installed in the \Windows folder:

Click Start, click Run, type notepad, and then click OK.

Type the following text:

[boot loader]
timeout=30
Default= multi(0)disk(0)rdisk(0)partition(1)\windows
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\windows=”<OperatingSystem>”
Note The value that is represented by the <OperatingSystem> placeholder depends on the configuration of the Windows XP computer that you are trying to access. For example, if you are trying to start a Windows XP Professional computer, this value is as follows:
Microsoft Windows XP Professional

Click the File menu, and then click Save As.

Select 3 ½ Floppy (A:) from the Save in drop-down list, type Boot.ini in the File name text box, and then click Save.

Note If your computer starts from a SCSI hard disk drive, you may have to replace the multi(0) entry with scsi(0). If you are using scsi(x) in the Boot.ini file, copy the correct device driver for the SCSI controller that is used on the computer to the root of the boot disk, and then rename the device driver to Ntbootdd.sys. Change the disk(0) number to represent the SCSI-ID of the hard disk drive you want to start. If you are using multi(x) in the Boot.ini file, you do not have to change the code in the Boot.ini file.
4. Insert the floppy disk into the floppy disk drive of your computer, and then restart Windows XP.
