Hi ,

Instead of using a native solution for more controlled internet sharing you can download and install "Sygate" Internet connection sharing software .

Good Luck

There is no utility that comes natively with XP to monitor traffic on an ICS connected LAN. I assume you are not directly connected to the ICS computer, and are running through a Switch or Hub? And you do not have access to this to see how many lines are connected?

If this is the case, you can download and install a packet sniffer and place it within the LAN in front of the ICS computer. It will 'see' all packets traveling across the wire, and report the MAC addresses and IP Addresses to which they are bound. Since every NIC has a unique MAC address (and IP Address), you can see how many computers (NICs) there are in the LAN, and connected to the wire.


You can also use a utility like LanGuard Analyzer to search for all computers on the LAN:

The last time I checked the trial version is fully operational for 30 days.. I use it in my Corporate LAN to monitor all 1000 computers in my domain.

One other thing to keep in mind, since ICS uses the Class C subnet (this cannot be changed), it has a limit of 254 clients that can be attached.. just an FYI..

Good luck!

Hello my name is prakash i used window7 in my PC problem is me connect my tablet in my PC via cable and start internet but not open any sites why Please solve my problem Thanks

Hi Prakash, you will probably needs to provide a bit more information of the issue, but from what you are sying it sounds like you will need to turn on Internet Connection Sharing on you PC so your laptop can use the internet connection from your PC. Perhaps better solution will be to get wireless access point and use your tablet via the wireless.

If you have issues have a look at the link i shared.

To enable ICS, on your host computer:
  • Open Network Connections by clicking the Start button , clicking Control Panel, clicking Network and Internet, clicking Network and Sharing Center, and then clicking Manage network connections.
  • Right-click the connection that you want to share, and then click Properties.
Using ICS Internet Connection Sharing Windows Help

Set up a home office LAN which access internet through USB wireless gadget

The following networking job I have done in this Lab. It is enough for a small office to access or transfer file Printing and access of shared Internet in different type of operating system.

We have recently set up a home office (small laboratory) LAN. All the computers access the internet through a USB wireless (CMDA) dongle. The USB stick is Huawei EC168C and internet service provider is Reliance Infocom (India). But any USB internet dongle can be use to share internet in a LAN in the following way. And you don't need a router for that. In the areas where ISP cannot give wire line internet connection this type of USB wireless sticks are really helpful for home office.

Basic LAN Connection:

Here this lab has 4 PCs. One Windows XP, another Windows Vista starter and two RedHat Linux server systems. Here in this lab I have done the basic LAN connection using cat5 cable & RJ45 connector and an 8 port hub. I have connect the two windows based OS. Using cross cable I have connected two windows system with the hub. Then I put static IP address in Ipv4 of TCP/IP. After that I set workgroup name to join in a workgroup in windows PCs. Then I tried to ping the systems, and it was pinging. Then I have setup a home or small office network in both windows system. That I have enabled the Printer sharing. After that I can share file, data and printer through the system gateway.

Now I have to connect other two Linux PCs in this network. With same cross cable I have joined the both Linux system with the hub. Then to detect the Ethernet device I have put down "DEVICE=eth0" entry in /etc/sysconfig/network-scripts/ifcfg-eth0 file. Then I set IP address in Ethernet device in network configuration in graphical mode (or System-config-network in text mode).After doing this job I restart the network service with "service network restart" command. Then I am trying to ping the systems to one another, And It was pinging.

Now Linux system can access with each other and files also shared through SSH, Telnet,FTP using process and command.

Linux Configuration:

I have configured the Linux system in the following way. First I have set the host name in /etc/sysconfig/network file by VI editor. Next I have edit /etc/sysconfig/network-scripts/ifcfg-eth0 file with "Device=eth0" to detect the Ethernet device. After that I have put the IP add in network configuration file and Restart the network service. To keep the eth0 on permanently I also use the chkconfig command.

After doing this job File sharing can be possible through network file sharing (Nfs). I have install Nfs package & shared the nfs dir by editing exports file. Then I am trying to automount the NFS dir by automounting process. So that I put automounting entry of nfs file in fstab file. After that it's automounted in other system's mount location.

Windows & Linux Networking:

Through basic LAN both OS can only ping each other. To share file or data samba server (a client server in Linux) must be configured in Linux system. So I Install smb rpm package from yum repository. Then I have Configure the samba/smb.conf file. I put the Workgroup name on Workgroup column of samba/smb.conf file. Then I Set the network IP without host to route in network in Host allow column. At last I put down all details of Samba dir, users at the end of the configuration file set the samba password. After that I restart the samba demon to up the samba server. Now files can shared through samba server. In windows I Set the workgroup name pairs with samba server and also set username and password same as samba server. Now I trying to send or access file through samba in both OS and it happened.

USB Net Connect:

Here in this lab workers are use internet from an Usb net connect. So it must be shared in Network. It is too fast so shared internet can be access easily. In Windows XP system I connect the USB netconnect & share it in network. IF all the network setting is ok then all the systems can access shared internet through gateway. Here all users use this shared internet now.

Access of Another System:
VNC Server & Viewer is software through which we can access of another system easily. I just install the software & set the password. Then I run the vnc server. After that I Put the IP add of vncserver from vncviewer of another system and type the password & start access the vnc server system. It can be access form WAN also. I just Run the Vnc server and connect the internet and I got a Wan IP add provided by ISP.

How to Share your Internet Connection through laptop's WLAN(Wifi) card?

Every Windows Operating System after Windows 98 can share its Internet Connection using this Technique. Microsoft defines this technique as Internet Connection Sharing (ICS). But setting ICS is very obscure to most of the users. This comes very useful if you live with your roommates and you guys have single internet source like a USB modem Connected to one laptop only. Using Internet Connection Sharing(ICS) that laptop can Broadcast its Internet to other laptops in the room. Technically, the range of a laptop's WLAN adapter is around 20-25 meters. So it can easily handle near by rooms also. This can also be done with a PC having a WLAN card.
To setup and broadcast your internet it is mandatory that you are accessing internet using anything other than Your WLAN card like a USB modem, Ethernet etc. This is because your Wireless adapter(WLAN) will be used for Broadcasting your Internet connection to your friends.
Server laptop:- Laptop with Internet Connection.Client Laptop:- Laptops accessing the internet of server laptop.
Follow the steps to share your internet it goes:--0b73509.gif
  1. Open the "Control Panel" of the laptop that is accessing Internet and go to "Network and Internet" then "Network and Sharing Center".
  2. On the right side of the "Network and Sharing Center" click the "Change Adapter Settings" and you will see all the available network adapters in your laptop.
  3. Now Right-Click the adapter through which you access internet and click "Properties" option. The properties window will open.
  4. In "properies" Window click the "sharing" tab check "Allow other network user to connect through this computer's Internet connection"97ac799.jpg
  5. In the sharing tab, Select "Home networking connection" type as "Wireless Network Connection" click "OK" and select "Yes" to the Confirmation warning. see above image.
  6. Now Right-Click the "Wireless Network Connection" in "Change Adapter Settings"and Open Its Properties.
  7. In "Wireless Network Connection Properties" Double-click the "Internet Protocol Version 4(TCP/IPv4)" and select the "Use following IP address"
  8. Enter the IP address as "" and "Subnet mask" as ""
  9. Leave all other fields blank in Server laptop, which has access to internet.0219162.jpg
  10. Now setup a wireless "ad hoc" computer to computer connection using "setup a new connection or network" in "network and sharing center" and Name it as anything like "Internet_sharing".c2debe7.jpg3a69972.jpg
  11. Now bring other laptops that will use the Shared Internet connection.
  12. Open "Change adapter Setting" (Described in step 2).
  13. In "Change adapter settings" Right-click "wireless Network Adapter" and Click its properties.
  14. In "Wireless Network Connection Properties" Double-click the "Internet Protocol Version 4(TCP/IPv4)" and enter following IP address:-
  15. IP address-"", Subnet mask "", Default gateway-"" and Preferred DNS server: "".
  16. Use the same step from 11 to 15 to connect other laptops and Increase the IP address by +1. Ex-, & so on. Rest of the settings like Default gateway etc will be same on all laptops. Only the server laptop will have blank entries in these settings.
  17. Now connect all the laptop with the Wireless network(ad-hoc) named "Internet-sharing" that you had previously broadcasted in step 10 in server laptop.
  18. Now in the server laptop, disconnect and then reconnect the internet connection(This is a necessary step for Internet Connection sharing(ICS) to work).
  19. Now access internet in all laptops...ENjoy.
Note:- For Advance Users.. this information is necessary only--The IP address of server laptop work as the "Default gateway" and Preferred DNS server of Client laptop and on server laptop these fields are blank. Use same series of IP address as used in the server.

Go into network set up a shared Internet connection using ICS (Internet Connection Sharing) You can use Internet Connection Sharing (ICS) to share an Internet connection among two or more computers on a network. First, you need one computer, called the host computer, that is connected to the Internet and that has a separate connection to the other computers on your network. You enable ICS on the Internet connection. The other computers on your network then connect to the host computer, and from there to the Internet through the host computer's shared Internet connection.
If your computer is connected to a network, network policy settings might prevent you from completing these steps.
On the host computer (the computer whose Internet connection you plan to share):
  1. ? to open Network Connections.
  2. Right-click the connection that you want to share, and then click Properties.getcontent.aspx?assetid=18abb370-ac1e-4b6b-b663-e028a75bf05b&documentset=en-us&renderkey=signed1 If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
  3. Click the Sharing tab, and then select the Allow other network users to connect through this computer’s Internet connection check box.

Server cannot see wireless workgroup machines but shares Internet

Disable any firewalls on the machine like Windows firewall or any other firewall like Norton, McAfe, ZoneAlarm and something like that. Or if you have firewall policies or access rules, you must enable the sharing there.

Limit or no conectivity problem

I understand that you are using the Windows Internet Connection Sharing to share your internet connection to your other computer.

If you don't have a router to share the connection then you are using Windows ICS connection.

When you enable ICS, the network adapter connected to the local area network is assigned a static IP address of

You can check this site for more information

You can try to connect the two computers first without the internet connection.

Example : PC A
You can set the IP addresses manually, just set the tcp/ip properties and from that area you can set the IP address manually.

And for PC B
You dont need to set the ip address for the gateway and dns since you are just testing the connection of the two computer.

They should belong to the same workgroup example HOME and set the computer name to PC1 and PC2.

You can right click MY COMPUTER then select PROPERTIES then you will able to see the computer name.

To start the wizard
Choose Control Panel from the Start menu.
Click Network and Internet Connections, and then click Set up or change your home or small office network.

Setting up 16 port switch

Dear This is the step You can get a complete home network up and running in 10 easy steps. Here's a summary of what's involved: Take stock of your existing hardware. If you wish to share an Internet connection using Internet Connection Sharing (ICS), choose which computer will be your ICS host. Decide what type of network technology you wish to use. Make a list of the hardware you need for each computer. Install the network adaptors and install your modem on the ICS host computer. Physically cable the computers together. Switch on all computers, printers and other peripherals. Make sure the ICS host is connected to the Internet. Run the Network Setup Wizard on the ICS host. Run the Network Setup Wizard on the other computers on the network. Let's take that step by step. 1. Take stock of your hardware Note each computer's location and its hardware, including peripherals such as printers and modems. 2. Choose your ICS host If you wish to share an Internet connection between your computers using Internet Connection Sharing (ICS), choose which computer will be your ICS host. The ICS host has a direct connection, either by dial-up modem or high-speed link, to the Internet and provides access to the Internet for other computers on the network. Ideally, the host should be a computer running Windows XP. I'll assume you have made this choice in the following steps. Apart from XP's easy handling of ICS, by using an XP computer as your ICS host you get the benefits of using the Internet Connection Firewall. 3. Choose a network technology The most common choices are Ethernet and wireless LANs. For an Ethernet LAN you will need to install a network interface card, or NIC, in each computer and run cabling between the computers. If you don't like the idea of opening your computer to install a network card, look for a USB adaptor instead. Depending on the size of your network, you may also need a network hub or router to provide interconnection between PCs on the LAN. Two PCs can get by using an RJ-45 crossover cable; three or more computers require a hub or multi-speed hub (called a switch). If you have a high-speed Internet connection, a high-speed router is a good option. The Network Setup Wizard includes links to detailed advice about configuring your network, including help on designing a network layout to suit your home. If you opt for a wireless LAN, you'll also need a NIC for each PC (there are versions which use USB adaptors as well). The big benefit for home environments is that a wireless LAN does away with the need for cabling. On the down side, though, wireless LANs tend to be slower, less robust and appreciably more expensive than traditional Ethernet LANs. In particular, wireless LANs do not always live up to their stated working range, and you may find factors such as your home's construction and design, plus interference from other devices affect your wireless LAN's performance. You may need to add an expensive Access Point to extend the range of the LAN and, even so, it may not be sufficient. The bottom line is, if you decide to go the wireless route, make sure the store will refund your money if the LAN will not provide reliable performance within the specified range. 4. Make a list of hardware needed Make a list of the hardware you need for each computer, not forgetting any cabling, and buy it. If you're a little dazzled by the choices and configurations, consider purchasing a networking kit. These kits contain all you need to set up a two- or three-PC network. If possible, look for hardware which features the Windows XP Logo, indicating it is fully compatible with XP. 5. Install the adaptors Install the network adaptors and install your modem on the ICS host computer (you can also let the computers connect to the Internet independently by installing modems on each). 6. Cable the computers Physically cable the computers (and hubs or routers) together. Of course, you won't need to do this if you've chosen to go the wireless route. If you're installing an Ethernet network and have a lot of cabling work to do, you may prefer to get a professional to come in and do this work for you. It won't be cheap, but you can be sure you get the job done correctly and hopefully with minimal damage done to walls, ceilings and floors. 7. Switch it on Switch on all computers, printers and other peripherals. 8. Connect the ICS host Go to the ICS host computer and make sure it is connected to the Internet. 9. Run the Network Setup Wizard on the ICS host To run the Network Setup Wizard on the ICS host, click Start -> Control Panel -> Network And Internet Connections -> Setup Or Change Your Home Or Small Office Network. Follow the instructions in each screen and press Next to continue. XP's Network Setup Wizard takes much of the pain out of setting up a home network. The Network Setup Wizard will guide you through: Configuring your network adaptors (NICs). Configuring your computers to share a single Internet connection. Naming each computer. (Each computer requires a name to identify it on the network.) Sharing the Shared Files folder. Any files in this folder will be accessible to all computers on the network. Sharing printers. Installing the Internet Connection Firewall to guard you from online attacks. 10. Run the Network Setup Wizard on all computers To do so: Insert the Windows XP CD in the first computer's drive. When the XP Welcome Menu appears, click Perform Additional Tasks. Click Setup Home Or Small Office Networking and follow the prompts. Repeat steps 1 to 3 for each computer on your network. Make sure you maintain an active Internet connection on your host computer as you proceed through this process. geekgirl.tip If you don't have a CD-ROM drive on one of the network computers, you can run the Network Setup Wizard from a floppy disk: While running the Network Setup Wizard on the ICS host computer, select the option to copy the Network Setup Wizard to a floppy disk. Once you've completed setup on the ICS host, take the floppy to the next computer and insert it in the drive. Double-click My Computer. Double-click 3½ Floppy (A:). Double-click netsetup.exe. The quickie XP network If you want a really easy networking experience and you have the hardware to support it, consider clean installing Windows XP on two or more computers. First install your network hardware (network interface cards, cabling, et cetera), then perform a new installation of Windows XP. During installation, XP will sense your hardware setup, ask for a name for each computer, and then ask which type of setup you wish to create. Select Typical Settings For A Default Network Configuration. That's it. Provided your hardware is XP-compatible, XP will create a LAN using the workgroup name MSHOME. Using your network Once you have your network up and running, you can easily access other computers on the network via My Network Places (click Start -> My Network Places). The Task Pane in My Network Places lets you access computers on your network and adjust settings. The Task Pane in My Network Places lets you view your network connections and view each of the computers in your workgroup (the workgroup consists of all computers on a network which share the same workgroup name ? by default, XP gives all computers on your home network the workgroup name MSHOME, although you can change this if you wish). When you initially open My Network Places, you'll see icons for the Shared Files folder of each of the active network computers. Sharing a printer With your home network installed, your PC suddenly gains all the advantages of the other PC's on the network. If you've been lusting after your sister's colour photo printer, you can now print directly to it from your own machine. Provided, that is, your sister decides to share her printer. (You might offer to let her share your laser printer in return as an inducement ? sharing works both ways.) To share a printer, on the computer which is directly connected to the printer: Click Start -> Control Panel -> Printers And Other Hardware -> Printers And Faxes. (Note: These steps will be a little different if you're sharing a printer on a PC running a version of Windows other than XP. For example, under Windows Me, you click Start -> Settings -> Printers.) Click the printer you wish to share. Click Share This Printer in the Task Pane. In the printer's Properties dialog, click the Sharing tab. Click Share Name and OK. Make a printer accessible to others on the network by sharing it. Once a printer has been shared you can access it from other computers on the network. To do so: Click Start -> Control Panel -> Printers And Other Hardware. Click Add A Printer. In the Add New Printer wizard, when asked whether the printer is a local or network printer, select the latter. In the next screen, select the option to Browse For A Printer and click Next. Select the appropriate printer from the list and continue with the wizard. Sharing files and folders Sharing a folder is even easier than sharing a printer: Open a folder (such as My Documents), click Make A New Folder in the Task Pane and name your new folder. With the new folder highlighted, click Share This Folder. In the Sharing tab of the Properties dialog box, select Share This Folder On The Network. Provide a descriptive name for the folder. This name should make it easy for others on the network to recognise the folder; it doesn't have to be the same as the folder name you selected in step 1. You can let other people on the network view and edit your files or view them only. If you want to protect your files from tampering, remove the tick from Allow Other Users To Change My Files. There are a variety of ways to access a shared folder. Here's one way: Click Start -> My Network Places -> View Workgroup Computers. Click the computer whose files you wish to access and then click the shared folder. You can create shortcuts to shared folders to make them easier to gdfgf
