Hi,
The problem is that XP is missing the extra file... There is now a download
from microsoft.... This is
Network Map Does Not Display Computers Running Windows XP
When you run Network Map in Windows Vista®, computers that are running
Microsoft Windows® XP do not appear on the completed diagram.
Cause
Network Map in Windows Vista diagrams the connections between network
devices to help you troubleshoot connectivity problems. Network Map uses a
discovery protocol called Link-Layer Topology Discovery (LLTD) in order to
query the other devices on the network to determine how the network is
organized. Computers that are running Windows Vista include the software
components that implement the LLTD protocol. For network computers that are
running Windows XP to appear on the map, they must have a discovery protocol
enabled that can respond to the mapping computer's requests.
Solution on Windows XP
For computers running Windows XP to appear on the Network Map diagram, you
must download and install the LLTD Responder component. By installing the
LLTD Responder, and enabling File and Printer Sharing in Windows Firewall, a
computer running Windows XP can respond to other Windows Vista computers on
the network that are attempting to create a network map.
The following procedures are performed on a computer running Windows XP.
To install the LLTD Responder onto a computer running Windows XP
1. Download the update for Windows XP from
http://go.microsoft.com/fwlink/?LinkId=70582
2. Run the update on the computer running Windows XP that you want to
appear on the Network Map.
3. On the Software Update Installation Wizard, click Next.
4. On the License Agreement page, read the license agreement, and if you
agree to the terms, click I Agree, and then click Next.
5. On the final page of the wizard, click Finish.
6. If you are prompted to do so, restart your computer.
You can verify that the LLTD Responder is successfully installed and
running.
To verify the LLTD Responder is installed and running
1. On a computer running Windows XP click Start, click Control Panel, and
then click Network Connections.
2. Click Local Area Network Connection, click Properties, and then view the
list of items used by the network connection.
3. Ensure that the Link-Layer Topology Discovery Responder check box is
selected.
Prior to generating a new Network Map in Windows Vista you must ensure that
Print and File Sharing is excluded from Windows Firewall filtering.
To exclude File and Printer Sharing from Windows Firewall
1. On a computer running Windows XP, click Start, click Control Panel, and
then click Network Connections.
2. Click Windows Firewall Settings, and then click the Exceptions tab.
3. If necessary, click Edit, and then select the File and Printer Sharing
check box.
Solution on Windows Vista
After performing the procedures in the preceding section, you can generate a
new Network Map for all computers on the network, including those running
Windows XP.
To generate a new Network Map and connect to all network computers
1. On a computer running Windows Vista, perform the following steps to
generate a new Network Map:
• Start Network and Sharing Center.
• On the right side of the Status section, click View full map.
2. Right-click the computer running Windows XP, and then click Open.
3. If connectivity issues persist, perform the following steps:
• Ensure that File and Printer Sharing is excluded from Windows Firewall on
the computer running Windows Vista.
• Consider excluding other services from Windows Firewall on the computer
running Windows Vista.
