Enabling Network Mapping in Windows Vista |
Windows Vista’s network map uses the Link Layer Topology Discovery (LLTD) protocol to determine the network’s topology. The cool thing about it is that this is the same discovery topology used by XBOX 360. Microsoft automatically enables network mapping on home (private) networks, so if you happen to have an XBOX 360 on your home network, it should show up on the network map. Unfortunately, mapping is disabled on domain networks and public networks by default.
To access the network map, open the Control Panel and click the Network and Internet link, followed by the Network and Sharing Center link. When the Network and Sharing Center opens, Windows will display a partial network map, as shown in Figure A.
Figure A: The Network and Sharing Center contains a partial network map
If you look at the above figure, you will notice that the upper, left corner of the window contains a link that you can use to view the full network map. If you click this link, you will see a message telling you that network mapping is disabled by default on domain networks, as shown in Figure B. The message goes on to tell you that your network administrator can use group policy to enable mapping. The ironic thing about this message is that you will receive this message even if you are logged in as an administrator.
Figure B: When you attempt to view the network map, Windows informs you that network mapping is disabled by default on domain networks
The problem with having network mapping disabled at the group policy level is that the group policy settings used to enable or disable network mapping simply do not exist in Windows Server 2003. This means that you will not be able to create a domain, site, or OU level policy that addresses network mapping until you have domain controllers in place that are running Windows Server 2008. For now the only way to enable network mapping is to modify the workstation’s local security policy.
To modify the local security policy, you must perform the steps that I am about to show you using administrative credentials. With that said, begin the process by opening a Command Prompt window. You can find the Command Prompt option on the Start menu under All Programs | Accessories.
When the Command Prompt window opens, enter the MMC command. Upon doing so, Windows will open an empty Microsoft Management Console. Select the Add / Remove Snap-In command from the console’s File menu. You should now see a list of all of the available snap-ins. Select the Group Policy Object Editor option from the list of snap-ins and click the Add button. You will now see a prompt asking you which group policy object you want to edit. The Local Computer policy should be selected by default, as shown in Figure C. Verify that this is the case, and click Finish, followed by OK.
Figure C: You must edit the Local Computer policy
At this point, the Local Computer Policy should be loaded into the Group Policy Object Editor console. Now, navigate through the console tree to Local Computer Policy | Computer Configuration | Administrative Templates | Network | Link Layer Topology Discovery. As you can see in Figure D, there are two group policy settings that fall within the Link Layer Topology Discovery section.
Figure D: There are two group policy settings that fall within the Link Layer Topology Discovery section
The first group policy setting that is available to you is the Turn on Mapper I/O (LLTDIO) Driver setting. As I mentioned earlier, network mapping works by using the Link Layer Topology Discovery protocol, which is exactly what this group policy setting controls. If you right click on this setting and choose the Properties command shown in the resulting shortcut menu, you will see the properties sheet that is shown in Figure E.
Figure E: To enable network mapping, you must enable the Turn On Mapper I/O (LLTDIO) Driver setting
To enable network mapping, you must enable the Turn On Mapper I/O (LLTDIO) Driver setting. As you can see in the figure though, simply enabling this setting does not enable mapping. You must use the screen’s check boxes to determine in which situations you want to allow operation. By default, network mapping is enabled on private networks (home networks), so the screen contains an option to prohibit operation while on a private network, not to allow operation on a private network.
The other two options allow the mapper to operate in a domain environment and on a public network respectively. Go ahead and select the Allow Operation While in Domain check box, but you probably do not want to allow operations while in a public network for security reasons.
Technically speaking, enabling the Mapper I/O (LLTDIO) Driver is sufficient for enabling network mapping. As you will recall though, there is another group policy setting available to you. The Mapper I/O (LLTDIO) Driver allows you to map your network, but the Responder (RSPNDR) Driver (which is controlled by the second group policy setting) allows you to actually extract information from devices on your network. Some of the device details that you will be able to extract include the device’s manufacturer and model number.
The responder has two basic purposes. First, it allows you to right click on a device shown on the network map and get extra information about the device. This makes the network map useful for inventory purposes. The responder’s second purpose is to assist you in diagnosing network problems. Right now not every network device is responder aware, but eventually responder use will become more widespread.
To enable the responder, right click on the Turn on Responder (RSPNDR) Driver setting and choose the Properties command from the resulting shortcut menu. When you do, you will see a screen that is very similar to the one that is shown in Figure E. Again, you should enable operation while in a domain, but avoid allowing operation while in a public network.
If you go back to the Network and Sharing Center and click the View Full Map option, you will see a network map similar to the one that is shown in Figure F. The first thing that you will probably notice about the figure is that only two PCs actually appear on the network map. The reason is because these two machines are the only ones running Vista. The other machines are running Windows XP or Windows Server 2003, which do not provide the necessary topology information.
Figure F: We have enabled the network map
If you hover over the devices shown on the network map, Vista displays some basic information about the device. The information varies depending on the device’s type and capabilities. For example, if I hover over the switch, Windows simply gives me the opportunity to assign a name to the switch. If I hover over my gateway though, Windows provides information such as the gateway’s IP address and MAC address. Right clicking on the gateway and selecting the Properties command from the shortcut yields more information. I have blurred some of this information in Figure G for security reasons, but you should still be able to get an idea of the types of information that Vista provides thanks to the responder.
Figure G - Vista provides information about individual devices

Use the Inbox Repair tool
If you can't open your Personal Folders file (.pst) (Personal Folders file (.pst): Data file that stores your messages and other items on your computer. You can assign a .pst file to be the default delivery location for e-mail messages. You can use a .pst to organize and back up items for safekeeping.) or your Offline Folder file (.ost) (Offline Folder file: The file on your hard disk that contains offline folders. The offline folder file has an .ost extension. You can create it automatically when you set up Outlook or when you first make a folder available offline.), or you suspect that your .pst or .ost data file is corrupt, you can use the Inbox Repair tool (Scanpst.exe), to diagnose and repair errors in the file.
1. Quit Microsoft Outlook if it's running.
2. Double-click Scanpst.exe, located at drive:\Program Files\Common Files\System\MSMAPI\LocaleID folder - where LocaleID is the locale identifier (LCID) for the installation of Microsoft Office. The LCID for English - United States is 1033.
3. In the Enter the name of the file you want to scan box, enter the name of the .pst or .ost file that you want to check, or click Browse to look for the file.
4. To specify scan log options, click Options, and then click the option you want.
5. Click Start.
6.
When the scanning is completed, and if errors were found, you will be prompted to start the repair process.
To change the name or location of the backup file created during the repair process, in the Enter name of backup file box, enter a new name, or click Browse to look for the file.
7. Click Repair.
8. Start Outlook using the profile that contains the .pst file that you tried to repair.
9. On the Go menu, click Folder List (Folder List: Displays the folders available in your mailbox. To view subfolders, click the plus sign (+) next to the folder. If the Folder List is not visible, on the Go menu, click Folder List.).
In the Folder List, you may see a Recovered Personal Folders folder containing default Outlook folders or a Lost and Found folder. The recovered folders are usually empty, because this is a rebuilt .pst file. The Lost and Found folder contains folders and items that the Inbox Repair tool recovered. Items that are missing from the Lost and Found folder cannot be repaired.
10. If you see a Recovered Personal Folders folder, you can create a new .pst file, and then drag the items in the Lost and Found folder into the new .pst file. When you have finished moving all items, you can remove the Recovered Personal Folders (.pst) file, including the Lost and Found folder, from your profile.
Notes
* If you are able to open the original .pst file, you may be able to recover additional items from your damaged .pst file. By default, the Inbox Repair tool creates a file called file name .bak, which is a copy of the original .pst file with a different extension. The .bak file is located in the same folder as your original .pst file. You may be able to recover items from the .bak file that the Inbox Repair tool could not recover. Make a copy of the .bak file, giving the file a new name with a .pst extension. Import the "bak.pst" file, and then move any additional recovered items to the new .pst file that you created.
* A copy of the log file is written to the same location as the .pst file.
