458 Chapter 9 • Using the Communication Tools From here, you can enter a recipient name and destination fax number, or you can click Address Book… to choose an existing entry from your address book, which will fill in this information for you.You can also add multiple recipi- ents for your fax. Once you have finished adding your recipient details, click Next and you will then be able to specify one of four different cover page templates. If you are following this through the text closely, you may notice that selection of a cover page is mandatory in this case.Although this appears to be optional due to the checkbox, it is grayed out.This is because we are interfacing directly through the fax device. If, for example, we had printed a document to the fax device, we would have had the option of including a cover page.You can enter any addi- tional information on the cover page that you may require by using the Subject Line and the Note field. Clicking Sender Information… allows you to enter your personal details, some of which will be included with the transmission.You need to fill in this information once only, and it will be then used as the default information for any subsequent faxes that you send. However, you may want to override this information, without wiping out your original details. If this is the case, select the checkbox Use the information for this transmission only and amend the details as necessary.The new details will be used only for this single transmission. Clicking Next again will take you to the schedule page where you can specify when the fax is sent—either immediately, at a specified time, or when discount rates apply (you may remember that you could amend the applicable times for discount rates when initially configuring the fax device). www.syngress.com Figure 9.10 Send Fax Wizard Dialog Box 189_XP_09.qxd 11/12/01 10:00 AM Page 458 Using the Communication Tools • Chapter 9 459 You can also adjust the priority of the fax. Clicking Next for the final time takes you into the summary page.This allows you to check the details of the fax, such as recipient, time, and so on, and also allows you to invoke the Windows Picture and Fax Viewer to preview the fax being sent.This is a useful applica- tion that allows you to edit, rotate, copy, annotate, and so on. Clicking Finish will complete the process and the fax will be sent, unless you specified that it should be scheduled for a later time. One notable feature is missing, unfortunately, and that is the ability to include attachments.There is a simple reason for this. If you are sending written informa- tion via fax, you will most likely be in your word processor and send it to the fax as a print job. However, I can’t help wondering if this is by design or an oversight. Before we finish our discussion on faxing, let’s cover the accessory programs that are installed when you install faxing. Click Start | All Programs | Accessories | Communications | Fax. From here you can do the following: ■ Invoke the Send Fax Wizard by selecting Send a Fax ■ Edit and create personal cover page templates with the Cover Page Editor ■ Manage faxes with the Fax Console The fax console is very useful console because it allows you to manage all the functions of faxing. It will enable you to carry out any of the functions that we have covered in this section, and it also has interfaces for sending a fax and the cover page editor. Connecting to the Internet One of the biggest and fastest growing communications mediums of all time is the Internet. Chances are that you will want to configure Windows XP to con- nect to the Internet at some point in time. Fortunately, the process isn’t a difficult one, and as long as you have a modem and telephone line, you are halfway there. For those of you working for a large corporation, chances are that you just start your browser and begin any configuration, except for perhaps having to con- figure your browser for a proxy server. In this section, we discuss how you can invoke the wizard that sets up a new connection and how you can use the avail- able options. To get started, click Start | Control Panel. If the Classic view isn’t visible, switch to it and double-click Network Connections. From the Network Tasks pane on the left-hand side, select Create a new connection which will invoke the New Connection Wizard. www.syngress.com 189_XP_09.qxd 11/12/01 10:00 AM Page 459 460 Chapter 9 • Using the Communication Tools Or, you could just click Start | All Programs | Accessories | Communications | New Connection Wizard, or from within Internet Explorer click Tools | Internet Options | Connections | Add.You will need Administrative privileges to configure a new connection and run the New Connection Wizard. If this is the first time you have carried out any connection-orientated tasks such as this, before the wizard is invoked, you will be prompted to enter some regional telephone settings.This includes your telephone number, area code, and the number to dial an outside line, if required. The wizard summarizes the tasks it can carry out, including the one we are interested in, which is connecting to the Internet, so click Next.The screen shown in Figure 9.11 allows you to select which particular function you want to carry out. Our choice is already selected by default so click Next.This is where things now get slightly interesting because you have the choice of the following: ■ Choosing from a list of ISPs ■ Setting up the connection manually ■ Using a CD that you received from an ISP These different options, by design, are meant to be very easy to follow. In addition, many ISPs have setup routines that mean you can bypass this wizard altogether. In fact, some automatically dial the Internet for you and run remote scripts that automatically set up your configuration. However, we are straying www.syngress.com Figure 9.11 New Connection Wizard 189_XP_09.qxd 11/12/01 10:00 AM Page 460 Using the Communication Tools • Chapter 9 461 slightly.The last option in the list when selected will tell you to insert the CD you received from the ISP and that the setup program will start automatically. Your ISP may have used the Connection Manager Administration Kit—a utility provided by Microsoft for just this purpose. It is one of the tools found within the Internet Explorer Administration Kit (IEAK), and although this is a tool targeted mainly at ISPs, corporations use it as well. Let’s look at the other two options in turn. Choosing from a list of ISPs will present you with the dialog box shown in Figure 9.12. As you can see, if you are in the U.S., you can set up Internet access with MSN. For the rest of this, you are left with the last two options. Selecting Select from a list of other ISPs and clicking Finish will create a shortcut in the Online Services folder. Double-clicking this shortcut will dial a referral number to an online service that allows you to select from a list of Microsoft partner ser- vice providers in your region. Clicking File and Settings Transfer Wizard starts the wizard that will allow you to transfer settings that were previously cre- ated on another workstation to this one.This includes a variety of options such as desktop, display, e-mail from Outlook and Outlook Express, Internet Explorer, and dial-up connections.To do this, you will need a direct cable or LAN connec- tion. Or, you can save and import via floppy disk. The final option is to set up a connection manually. For new users, this is the most complicated method, and it allows you to set up your connection for dial- up or broadband access (you may find some ISPs referring to broadband as Point-to-Point Protocol over Ethernet (PPPoE), which is the access protocol www.syngress.com Figure 9.12 New Connection Wizard Internet Connections Choice Dialog Box 189_XP_09.qxd 11/12/01 10:00 AM Page 461 462 Chapter 9 • Using the Communication Tools used for broadband). In some ways, it seems fairly simplistic in that it prompts for phone number, username, and password. However, you will need to know a variety of connection settings, such as DNS entries, after the wizard has finished. This is the minimum information that you will require, which in most cases will be enough. Some ISPs may require some more obscure settings to be set, so you will need to check with them if you encounter difficulties. Collaborating with NetMeeting NetMeeting is a pretty cool program, especially as it comes free with the OS. It allows you to collaborate real-time with other people via your company’s LAN/WAN or the Internet. It provides the following features: ■ Chat Type and receive text data. ■ White boarding Work on virtual tablets with text and drawing tools. ■ Video conference Provided that the parties on the conference have a video camera installed, you can see and talk to each other. ■ Application sharing Share the application so that it is available to multiple users. ■ File transfer The ability to transfer files to the remote system with which you are communicating. To be able to use all the facilities that NetMeeting provides, you need the fol- lowing hardware: ■ Connection to the network on which you want to make NetMeeting calls, such as a dial-up modem, broadband, or LAN connection ■ Video camera, commonly referred to as a WebCam ■ Soundcard, preferably full-duplex ■ Speakers or headphones—headphones would be preferable in a busy office to prevent creating additional noise ■ Microphone, although some WebCams have these built-in If NetMeeting is already installed, you can invoke it by clicking Start | All Programs | Accessories | Communications | NetMeeting. If it isn’t, you need to install it. www.syngress.com 189_XP_09.qxd 11/12/01 10:00 AM Page 462 Using the Communication Tools • Chapter 9 463 To install NetMeeting, click Start | Run, click on Browse… to locate the file C:\program files\NetMeeting\conf.exe, click OK, and then click Open.The initial NetMeeting screen will be displayed, as shown in Figure 9.13. Click Next, and you will be prompted to enter some information about your- self, such as name, e-mail address, location, and any comments. Note that you will not be able to proceed until you enter your name and e-mail address; the location and comment fields are optional. Click Next, and you will have the options of log- ging onto a directory and having your details stored in the directory, specifically the Microsoft Internet Directory. Logging onto the directory allows you to look up other people in the same manner as you would a telephone directory, and storing your details gives you your own entry. Click Next, and you can specify the con- nection speed that you will be using to make NetMeeting calls.This optimizes NetMeeting according to the speed you select. Click Next, and this just gives you the option of placing shortcuts to NetMeeting on your desktop and in the quick launch area of the taskbar (see Chapter 3). Click Next, and this screen just warns you that you are going to configure the audio settings, and that you should close any other programs that play or record sounds, so click Next again.The first screen in the audio tuning process allows you to test and adjust the volume settings for your speakers/headphones.Adjust the volume slider as necessary. If you don’t hear any sounds coming from your speakers, you need to start troubleshooting. Check your physical connections; if these appear to be okay, check out the Sounds and Devices applet in Control Panel when using Classic View. This allows you to access and configure all aspects of your sound card and provides a convenient link to a troubleshooter if you are experiencing problems. In fact, you should probably www.syngress.com Figure 9.13 NetMeeting Initial Configuration Dialog Box 189_XP_09.qxd 11/12/01 10:00 AM Page 463 464 Chapter 9 • Using the Communication Tools go here before invoking NetMeeting for the first time to check that everything is working properly.When you have finished testing audio, click Next.The following screen allows you to test the level of speech through your microphone and allows you to adjust the recording level. Click Next when you have finished and then click Finish to complete the configuration. NetMeeting will now start and you will see the screen shown in Figure 9.14. The majority of the commands, like many well designed applications, are also available via the traditional menu structure. First, we discuss the commands you can invoke on this front screen.When we move onto the menu structure, we skip any commands we have already covered. (We also assume that all of the default settings are still in place.) The first thing to do is establish your first call.After all, there is little point in doing anything in NetMeeting without having someone to share it with. If you refer back to Figure 9.14, you will see the drop-down list box directly below the menu structure.You can type in the workstation name or IP address, or you can choose one that you have already called previously in this field. Or, you can use the phonebook icon on the right-hand side to search a directory for a name. Anyway, once the field is filled in, click the phone icon.A message box will appear waiting for a response from the other end while also giving you the www.syngress.com Figure 9.14 NetMeeting Console 189_XP_09.qxd 11/12/01 10:00 AM Page 464 Using the Communication Tools • Chapter 9 465 opportunity to cancel the call. If the call is accepted, the status bar will show that you are in a call (providing it is visible), and the title bar will also change to show that you are connected.To end the call at any time, you can click the icon that shows the phone being hung up. www.syngress.com NetMeeting Architecture Issues The Microsoft Directory is an example of what is known as an Internet Locator Server (ILS). Some organizations will only want to use NetMeeting for internal purposes and implement their own ILS. Fundamentally, an ILS is a directory service based on Lightweight Directory Access Protocol (LDAP). To set up your own ILS, you can use the Personalization and Membership features of Site Server 3.0. You can find instructions for doing this in the Microsoft article HowTo: Set Up Internet Locator Server 3.0 on Site Server 3.0 [Q238994], which you can find on the Microsoft Web site or Technet. Once you have set up your own ILS server, you will probably want to remove the default ILS as an option from your NetMeeting clients. To do this, carry out the following: 1. Within NetMeeting, select Tools | Options. Ensure that the General tab is selected and select Logon to a directory when NetMeeting starts. 2. In the Directory field, overtype any existing entry with the name of your own ILS. 3. Using the Registry editor, delete all of the values except Default in the following key: HKEY_USERS\.Default\Software\ Microsoft\Conferencing\UI\Directory. Once you have done this, you can use one of the default policies for NetMeeting to stop users adding their own ILS entries. You could also create your own custom .adm file and apply the above Registry change via group policy as well. This will enable you to easily modify all of your clients if the directory name ever changes. Another architectural consideration that you need to take into account is passing NetMeeting traffic through firewalls. NetMeeting requires the following ports to be available: Configuring & Implementing… Continued 189_XP_09.qxd 11/12/01 10:00 AM Page 465 466 Chapter 9 • Using the Communication Tools Below the NetMeeting display screen, which is directly underneath the drop- down list box, are three more icons.The first is similar to your VCR and allows you to start and stop the video stream that is shown in the window.The second icon, which looks like a rectangle within a rectangle, is picture-on-picture.This will show your own image within the video received from the calling or called party.The third icon allows you to control what is shown underneath these; by default this is a picture of a person. Click this and it shows you the names of the people who are on the call and changes its image to that of a microphone and speaker.When the microphone and speaker controls are visible you can adjust the audio levels and also mute them by deselecting the checkboxes. www.syngress.com ■ 389 Internet Locator Server (TCP) ■ 522 User Location Service (TCP)—required only if supporting NetMeeting 1.0 clients ■ 1503 T.120 (TCP) ■ 1720 H.323 call setup (TCP) ■ 1731 Audio call control (TCP) ■ Dynamic H.323 call control (TCP) ■ Dynamic H.323 streaming (Real Time Protocol over User Datagram Protocol) Some firewalls cannot support an arbitrary number of virtual internal IP addresses, or they cannot do so dynamically. If your firewalls suffer from this limitation, you will be able to send audio and video transmission to outside the firewall, but it will not accept incoming traffic of this nature. In a worst-case scenario, you will not be able to use NetMeeting through your firewall at all if it is a Web proxy server with no generic connection-handling mechanism. Using NetMeeting over firewalls is a complicated business, and opening up all the ports for NetMeeting can expose your organization to security breaches. Also, Microsoft appears to be moving more towards the use of H.323 GateKeeper. When used in conjunction with ISA server, you can then use the GateKeeper in place of a directory and also have a means of using NetMeeting through a firewall. This subject is beyond the scope of this book, and if you require further information, you can find it in Configuring ISA Server by Thomas and Deborah Shinder, (Syngress) ISBN 1-928994-29-6. 189_XP_09.qxd 11/12/01 10:00 AM Page 466 Using the Communication Tools • Chapter 9 467 Now that we have covered some of the basics, we ca now move on to the some of the really cool functionality that NetMeeting provides.The first button on the left-hand side at the bottom of the screen invokes application sharing. Figure 9.15 shows two applications that are available for sharing: Desktop and Paint.The desktop application is always available and sharing this enables any application to subsequently be made available. By default, no running applications are shared out; to share them, you will need to highlight the one you want your calling party to have access to and click Share. If you want to stop sharing a pro- gram, you click Unshare.The presence of the Unshare All button indicates that you are not limited to sharing one application at a time. As soon as you share an application, a screen is automatically displayed on the called party’s screen, and a tick is placed next to the application in your list of available applications to indicate that it is being shared.You should only enable the Share in true color checkbox if you have a connection with high-band- width. Selecting it will enhance the experience but degrade performance. Programs are only shared as read-only unless you specify otherwise, this means that the called party can only see what you are doing with the application and cannot interact with it. On the receiving end, the screen has a Control menu, but these are grayed out. However, you can allow them to take control and interact with it by clicking Allow Control.When you do this, the title of www.syngress.com Figure 9.15 Application Sharing Configuration Dialog Box 189_XP_09.qxd 11/12/01 10:00 AM Page 467 [...]... www.syngress.com 477 189 _XP_ 09.qxd 478 11/12/01 10:00 AM Page 478 Chapter 9 • Using the Communication Tools click Receive, and the screen should look like Figure 9.24 Switch to the other session and select Transfer | Send File from the menu and browse to a file that you want to send—preferably from a different path than the one it is it is being sent to Again, leave the protocol as default and click Send...
