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.

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.

Using Remote Assistance in Windows XP

It's late at night, and your computer is acting weird. What did you do wrong? Luckily, your co-worker's kid across town just got Windows XP, and he's already mastered it. But his parents won't let him out at night. If only he could fix your computer for you. . . .

With Windows XP's Remote Assistance, he can. If you turn on Remote Assistance, another person can log onto your computer and control it, just as if they were sitting in front of it. They can tweak your computer, setting up what needs to be done, and your computer will run as good as new. (At least, that's the concept.)

To load Remote Assistant, click the Start button, choose Help and Support and choose Remote Assistance. Choose Invite Someone to Help You from the program's screen, and send a message using Outlook Express or Microsoft MSN Messenger. The recipient accepts your request, and he or she sees your computer's screen on their monitor. You two chat back and forth, typing messages, and the helpful soul moves around your mouse, clicking the right things, until the situation is fixed.

Expect to see it used by technical support staffs in the future.
