Obtain Remote Assistance by Sending an E-mail Message in Windows XP

This article describes how to obtain help by using the Remote Assistance feature in Microsoft Windows XP.

Remote Assistance allows a remote connection to your computer that can be used to view your computer screen, participate in real-time chat and, with your permission, remotely control your computer.

Note: The following requirements must be met before you can use Remote Assistance:

• Both the local and the remote computer must be using either Windows Messenger or a Messaging Application Programming Interface (MAPI)-compliant e-mail program such as Microsoft Outlook or Outlook Express.
  
• Both computers must be connected to the Internet while using Remote Assistance.

Note: If your computer is behind a firewall, you may need to reconfigure the firewall to allow Remote Assistance. Contact your network administrator before using Remote Assistance.

• Click Start > Help and Support. The Help and Support Center dialog box appears.
• Under Ask for assistance, click Invite a friend to connect to your computer with Remote Assistance. The Remote Assistance pane appears.
• Under Remote Assistance, click Invite someone to help you.
• Under or use e-mail, type your assistant's e-mail address in the Type an e-mail address box, and then click Invite this person.
  Note: Click Address Book if you want to select a contact from the address book.
  The Remote Assistance - E-mail an Invitation page appears.
  
• In the From box, type the name or identification that you want.
• In the Message box, type the message that you want, and then click Continue.
• Under Set the invitation to expire, select the duration that you want to allow the invitation for assistance.
  Click to clear the Require the recipient to use a password check box if you do not want to password-protect the remote connection.
  Note: Using a password is recommended.
  
• If you protect this connection with a password, type the password that you want your assistant to use in the Type password box. Retype that password in the Confirm password box, and then click Send Invitation. The invitation is sent using your e-mail program. You receive the following message:

Your invitation has been sent successfully. Note: You must communicate this password to the remote assistant in order for the Remote Assistance session to be created.

• When your remote assistant accepts your invitation, you receive the following message

Assistant has accepted your Remote Assistance invitation and is ready to onnect to your computer.
Do you want to let this person view your screen and chat with you? where Assistant is the name of the remote assistant.

• Click Yes.
  The Remote Assistance dialog box appears. The remote assistant can view your computer screen and chat with you in real time.
  
• If the remote assistant wants to remotely control the computer, you receive the following message:

Assistant would like to share control of your computer to help solve the problem.

Do you wish to let Assistant share control of your computer? (where Assistant is the name of the remote assistant).

• To accept, click Yes.

The remote assistant can now control your computer remotely. This includes the ability to shut down the computer.
Note: Do not use the mouse while the remote assistant controls the computer.

Troubleshooting The ability to control your computer remotely is disabled by default.

The computer appears to stop responding
When you use Remote Assistance over a dial-up connection, the computer may appear to stop responding (hang) or may respond slowly. This behavior may be caused by the slow speed of the Internet connection. For best results, use Remote Assistance over a high-speed Internet connection.

Remote Assistance allows access to sensitive data
The remote assistant can see as well as, with your permission, gain access to the information on your computer. For this reason, invite only trusted sources to remotely assist you.

Note:

The PRC service was responsible for the blaster worm. Even though its fixed, i believe that its a horrible piece of software to implement in an operating system. Hasn't Microsoft heard of moore's law??
