Set Permissions for Shared Files and Folders

1072

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.

To enable Internet Connection Sharing on a network connection

You must be logged on to your computer with an owner account in order to complete this procedure.

Open Network Connections. (Click Start, click Control Panel, and then double–click Network Connections.)

Click the dial–up, local area network, PPPoE, or VPN connection you want to share, and then, under Network

Tasks, click Change settings of this connection.

On the Advanced tab, select the Allow other network users to connect through this computer's Internet connection check box.

If you want this connection to dial automatically when another computer on your home or small office network attempts to access external resources, select the Establish a dial–up connection whenever a computer on my network attempts to access the Internet check box.

If you want other network users to enable or disable the shared Internet connection, select the Allow other network users to control or disable the shared Internet connection check box.

Under Internet Connection Sharing, in Home networking connection, select any adapter that connects the computer sharing its Internet connection to the other computers on your network. The Home networking connection is only present when two or more network adapters are installed on the computer.

To configure Internet options on your client computers for Internet Connection Sharing

Open Internet Explorer. Click Start, point to All Programs, and then click Internet Explorer.) On the Tools menu, click Internet Options.

On the Connections tab, click Never dial a connection, and then click LAN Settings.

In Automatic configuration, clear the Automatically detect settings and Use automatic configuration script check boxes.

In Proxy Server, clear the Use a proxy server check box.

Speed up your browsing of Windows 2000 & XP machines

Internet_Explorer_7_Logo

Here's a great tip to speed up your browsing of Windows XP machines. Its actually a fix to a bug installed as default in Windows 2000 that scans shared files for Scheduled Tasks. And it turns out that you can experience a delay as long as 30 seconds when you try to view shared files across a network because Windows 2000 is using the extra time to search the remote computer for any Scheduled Tasks. Note that though the fix is originally

intended for only those affected, Windows 2000 users will experience that the actual browsing speed of both the Internet & Windows Explorers improve significantly after applying it since it doesn't search for Scheduled Tasks anymore. Here's how :

Open up the Registry and go to :

HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version/Explorer/RemoteComputer/NameSpace

Under that branch, select the key :

{D6277990-4C6A-11CF-8D87-00AA0060F5BF}

and delete it.

This is key that instructs Windows to search for Scheduled Tasks. If you like you may want to export the exact branch so that you can restore the key if necessary.

This fix is so effective that it doesn't require a reboot and you can almost immediately determine yourself how much it speeds up your browsing processes.

How to make your Desktop Icons Transparent

Go to Control Panel > System, > Advanced > Performance area > Settings button Visual Effects

tab "Use drop shadows for icon labels on the Desktop"

Set the Search Screen to the Classic Look

Set the Search Screen to the Classic Look

When I first saw the default search pane in Windows XP, my instinct was to return it to its classic look; that puppy had to go. Of course, I later discovered that a doggie door is built into the applet. Click "Change preferences"

then "Without an animated screen character." If you'd rather give it a bare-bones "Windows2000" look and feel, fire up your Registry editor and navigate to:

HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ CabinetState.

You may need to create a new string value labeled "Use Search Asst" and set it to "no".

How to Remove Windows XP's Messenger

How to Remove Windows XP's Messenger

Theoretically, you can get rid of it (as well as a few other things). Windows 2000 power users should already be familiar with this tweak.

Fire up the Windows Explorer and navigate your way to the %SYSTEMROOT% \ INF folder. What the heck is that thingy with the percentage signs? It's a variable. For most people, %SYSTEMROOT% is C:\Windows. For others,

it may be E:\WinXP. Get it? Okay, on with the hack! In the INF folder, open sysoc.inf (but not before making a BACKUP copy first). Before your eyes glaze over, look for the line containing "msmsgs" in it. Near the end of that particular line, you'll notice that the word "hide" is not so hidden. Go ahead and delete "hide" (so that the

flanking commas are left sitting next to one another). Save the file and close it. Now, open the Add and Remove

Programs applet in the Control Panel. Click the Add / Remove Windows Components icon. You should see

"Windows Messenger" in that list. Remove the checkmark from its box, and you should be set. NOTE: there are other hidden system components in that sysoc.inf file, too. Remove "hide" and the subsequent programs at your own risk.

Windows XP and Symmetric Multiprocessing

 

Windows XP and Symmetric Multiprocessing

 


Symmetric multiprocessing (SMP) is a technology that allows a computer to use more than one processor. The

most common configuration of an SMP computer is one that uses two processors. The two processors are used to complete your computing tasks faster than a single processor. (Two processors aren't necessarily twice as fast as

a single processor, though.)

 

In order for a computer to take advantage of a multiprocessor setup, the software must be written for use with

an SMP system. If a program isn't written for SMP, it won't take advantage of SMP. Not every program is written for SMP; SMP applications, such as image-editing programs, video-editing suites, and databases, tend to be processor intensive.


SMP in Windows XP

 

Operating systems also need to be written for SMP in order to use multiple processors. In the Windows XP family, only XP Professional supports SMP; XP Home does not. If you're a consumer with a dual-processor PC at home,

you have to buy XP Professional. Windows XP Advanced Server also supports SMP.

 

In Microsoft's grand scheme, XP Professional is meant to replace Windows 2000, which supports SMP. In fact, XP Professional uses the same kernel as Windows 2000. XP Home is designed to replace Windows Me as the

consumer OS, and Windows Me does not support SMP.

 

The difference between XP Professional and XP Home is more than just $100 and SMP support. XP Professional has plenty of other features not found in XP Home; some you'll use, others you won't care about. Get more information on the differences by reading this article.
