When this initial screen appears, you can do either of the following:

Solicit Remote Assistance from someone by clicking the Invite Someone You Trust To Help You option, which displays the How Do You Want To Invite Your Trusted Helper screen, as shown in Figure 22-3 .

Accept a Remote Assistance invitation from someone or offer Remote Assistance to someone by clicking the Help Someone Who Has Invited You option, which displays the Choose A Way To Connect To The Other Person s Computer screen, as shown in Figure 22-4 .

The How Do You Want To Invite Your Trusted Helper screen (see Figure 22-3) lets you select from the following methods for soliciting Remote Assistance:

Save This Invitation To A File Selecting this option lets you save your Remote Assistance invitation file to a folder on your computer or to an available shared folder on the network . Use E-mail To Send An Invitation Selecting this option starts your e-mail client application, creates a new message, and attaches the invitation file to the message . Note that if you do not have an SMAPI-compatible e-mail client application on your computer, this option will be unavailable . Use Easy Connect Selecting this option creates and publishes your Remote Assistance invitation file to the cloud using PNRP and displays a 12-character password that you must communicate OOB to your Helper for him to accept your invitation . If, however, you previously used Easy Connect to establish a Remote Assistance session with the same Helper, the Helper can accept your invitation without any password required .

The Choose A Way To Connect To The Other Person s Computer screen (see Figure 22-4) lets you accept a Remote Assistance invitation from someone or offer Remote Assistance to someone . The following options are available on this screen for accepting a Remote Assistance invitation from someone:

Use An Invitation File Selecting this option lets you browse your local file system or network share for the Remote Assistance invitation from someone who needs your help . You will need the password associated with the invitation, which must be provided OOB by the User who needs help . Use Easy Connect Selecting this option lets you browse the PNRP cloud for the Remote Assistance invitation from someone who needs your help . The first time you use Easy Connect to help this individual, you will need the password associated with the invitation, which must be provided OOB by the User who needs help . For subsequent times that you use Easy Connect to help this individual, the password is not required .

To offer Remote Assistance to someone, click the Advanced Connection Option For Help Desk link at the bottom of Figure 22-4 . Additional steps for soliciting and offering Remote Assistance are described in the scenario sections later in this chapter .

emote assistance invitation files (.MsRcIncident) are XML-formatted file documents that include information used by the Helper s computer that will attempt

to connect. This ticket information is encrypted to prevent unauthorized users from accessing the information if e-mail or file transfer is used to send the invitation over an unsecured network. If the e-mail method is used to send the invitation file to the Helper, the invitation file is sent as an e-mail attachment with a filename of RaTicket.MsRcIncident. If the file transfer method is used instead, the invitation file is created by default on the desktop of the User s computer, and the filename of the invitation is Invitation.MsRcIncident.

Remote Assistance in Windows 7 and Windows Vista is implemented as a stand-alone executable called Msra .exe . You can initiate Remote Assistance sessions directly from the command line or by using scripts . The syntax and usage for this command is explained in Table 22-3 .
