All Kool Stuff for Window XP (Part-2)


Restricting Logon Access

If you work in a multiuser computing environment, and you have full (administrator level) access to your computer, you might want to restrict unauthorized access to your "sensitive" files under Windows 95/98.
One way is to disable the Cancel button in the Logon dialog box.
Just run Regedit and go to:

HKEY_LOCAL_MACHINE/Network/Logon

Create the "Logon" subkey if it is not present on your machine: highlight the Network key -> right-click in the left hand Regedit pane -> select New -> Key -> name it "Logon" (no quotes) -> press Enter. Then add/modify a DWORD value and call it "MustBeValidated" (don't type the quotes). Double-click it, check the Decimal box and type 1 for value.
Now click the Start button -> Shut Down (Log off UserName) -> Log on as a different user, and you'll notice that the Logon Cancel button has been disabled.



Remove the Recycle Bin from the Desktop

If you don't use the Recycle Bin to store deleted files , you can get rid of its desktop icon all together.

Run Regedit and go to:

HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/explorer/Desktop/NameSpace


Click on the "Recycle Bin" string in the right hand pane. Hit Del, click OK.


How to Rename the Recycle Bin

To change the name of the Recycle Bin desktop icon, open Regedit and go to:

HKEY_CLASSES_ROOT/CLSID/{645FF040-5081-101B-9F08-00AA002F954E}

and change the name "Recycle Bin" to whatever you want (don't type any quotes).



Provide Remote Assistance When Using a NAT Device

You can provide Remote Assistance to a friend who uses a Network Address Translation (NAT) device by modifying the Remote Assistance invitation using XML. Network Address Translation is used to allow multiple computers to share the same outbound Internet connection. To open a Remote Assistance session with a friend who uses a NAT device:

1. Ask your friend to send you a Remote Assistance invitation by e–mail.

2. Save the invitation file to your desktop.
3. Right–click the file, and then click Open With Notepad. You'll see that the file is a simple XML file.
4.Under the RCTICKET attribute is a private IP address, such as 192.168.1.100.
5. Over–write this IP address with your friend's public IP address. Your friend must send you his or her public IP address: they can find out what it is by going to a Web site that will return the public IP address, such as http://www.dslreports.com/ip.
6. Save the file, and then double–click it to open the Remote Assistance session.

Now, you'll be able to connect and provide them with the help they need. So that your inbound IP connection is routed to the correct computer, the NAT must be configured to route that inbound traffic. To do so, make sure your friend forwards port 3389 to the computer they want help from.


Ports That Are Used by Windows Product Activation

NTFS vs. FAT

To NTFS or not to NTFS—that is the question. But unlike the deeper questions of life, this one isn't really all that hard to answer. For most users running Windows XP, NTFS is the obvious choice. It's more powerful and offers security advantages not found in the other file systems. But let's go over the differences among the files systems so we're all clear about the choice. There are essentially three different file systems available in Windows XP: FAT16, short for File Allocation Table, FAT32, and NTFS, short for NT File System.


FAT16
The FAT16 file system was introduced way back with MS–DOS in 1981, and it's showing its age. It was designed originally to handle files on a floppy drive, and has had minor modifications over the years so it can handle hard disks, and even file names longer than the original limitation of 8.3 characters, but it's still the lowest common denominator. The biggest advantage of FAT16 is that it is compatible across a wide variety of operating systems, including Windows 95/98/Me, OS/2, Linux, and some versions of UNIX. The biggest problem of FAT16 is that it has a fixed maximum number of clusters per partition, so as hard disks get bigger and bigger, the size of each cluster has to get larger. In a 2–GB partition, each cluster is 32 kilobytes, meaning that even the smallest file on the partition will take up 32 KB of space. FAT16 also doesn't support compression, encryption, or advanced security using access control lists.

FAT32
The FAT32 file system, originally introduced in Windows 95 Service Pack 2, is really just an extension of the original FAT16 file system that provides for a much larger number of clusters per partition. As such, it greatly improves the overall disk utilization when compared to a FAT16 file system. However, FAT32 shares all of the other limitations of FAT16, and adds an important additional limitation—many operating systems that can recognize FAT16 will not work with FAT32—most notably Windows NT, but also Linux and UNIX as well. Now this isn't a problem if you're running FAT32 on a Windows XP computer and sharing your drive out to other computers on your network—they don't need to know (and generally don't really care) what your underlying file system is.

The Advantages of NTFS
The NTFS file system, introduced with first version of Windows NT, is a completely different file system from FAT. It provides for greatly increased security, file–by–file compression, quotas, and even encryption. It is the default file system for new installations of Windows XP, and if you're doing an upgrade from a previous version of Windows, you'll be asked if you want to convert your existing file systems to NTFS. Don't worry. If you've already upgraded to Windows XP and didn't do the conversion then, it's not a problem. You can convert FAT16 or FAT32 volumes to NTFS at any point. Just remember that you can't easily go back to FAT or FAT32 (without reformatting the drive or partition), not that I think you'll want to.

The NTFS file system is generally not compatible with other operating systems installed on the same computer, nor is it available when you've booted a computer from a floppy disk. For this reason, many system administrators, myself included, used to recommend that users format at least a small partition at the beginning of their main hard disk as FAT. This partition provided a place to store emergency recovery tools or special drivers needed for reinstallation, and was a mechanism for digging yourself out of the hole you'd just dug into. But with the enhanced recovery abilities built into Windows XP (more on that in a future column), I don't think it's necessary or desirable to create that initial FAT partition.

When to Use FAT or FAT32
If you're running more than one operating system on a single computer (see Dual booting in Guides), you will definitely need to format some of your volumes as FAT. Any programs or data that need to be accessed by more than one operating system on that computer should be stored on a FAT16 or possibly FAT32 volume. But keep in mind that you have no security for data on a FAT16 or FAT32 volume—any one with access to the computer can read, change, or even delete any file that is stored on a FAT16 or FAT32 partition. In many cases, this is even possible over a network. So do not store sensitive files on drives or partitions formatted with FAT file systems.



Make your Folders Private

•Open My Computer
•Double-click the drive where Windows is installed (usually drive (C:), unless you have more than one drive on your computer).
•If the contents of the drive are hidden, under System Tasks, click Show the contents of this drive.
•Double-click the Documents and Settings folder.
•Double-click your user folder.
•Right-click any folder in your user profile, and then click Properties.
•On the Sharing tab, select the Make this folder private so that only I have access to it check box.


Note

•To open My Computer, click Start, and then click My Computer.
•This option is only available for folders included in your user profile. Folders in your user profile include My Documents and its subfolders, Desktop, Start Menu, Cookies, and Favorites. If you do not make these folders private, they are available to everyone who uses your computer.
•When you make a folder private, all of its subfolders are private as well. For example, when you make My Documents private, you also make My Music and My Pictures private. When you share a folder, you also share all of its subfolders unless you make them private.
•You cannot make your folders private if your drive is not formatted as NTFS For information about converting your drive to NTFS

Install/Enable NetBEUI Under WinXP

If for some reason you need to install NetBEUI then follow these instructions.

**Note - You will need the WinXP CD in order to to this!

Support for the NetBIOS Extended User Interface protocols (also called NetBEUI or NBF) in Windows XP has been discontinued. If your configuration requires temporary use of NetBEUI for Windows XP, follow these steps:

To install the NETBEUI protocol:

- Locate the Valueadd/msft/net/netbeui directory on your Windows XP CD.Copy nbf.sys into the %SYSTEMROOT%SYSTEM32DRIVERS directory.

- Copy netnbf.inf into the %SYSTEMROOT%INF directory.

- In Control Panel, click Network and Internet Connections and then click Network Connections.

- Right-click the connection you want to configure, and then click Properties.

- On the General tab, click the INSTALL button to add the NetBEUI protocol.

How to Convert FAT to NTFS file system

To convert a FAT partition to NTFS, perform the following steps.

Click Start, click Programs, and then click Command Prompt.

In Windows XP, click Start, click Run, type cmd and then click OK.

At the command prompt, type CONVERT [driveletter]: /FS:NTFS.

Convert.exe will attempt to convert the partition to NTFS.

NOTE: Although the chance of corruption or data loss during the conversion from FAT to NTFS is minimal, it is best to perform a full backup of the data on the drive that it is to be converted prior to executing the convert command. It is also recommended to verify the integrity of the backup before proceeding, as well as to run RDISK and update the emergency repair disk (ERD).
