Hi
recently I set up a network which consists of 7 PCs, and I subscribed in the DSL so that some members can run the internet on their own PCs.
My question is the following: is there a way that let me block some PCs so that they can't access the Internet, note that I want them to access the shared files on the network but not the Internet.

Note: I'm using the speedtouch 546 modem. and all the PCs run Windows XP.
 
Assuming you're using XP:

One way to remove the ability to browse with IE is to use XP's set program access and defaults utility.

1. Click on the Start button
2. Click on set program access and defaults
3. Select the Custom pull down list
4. Deselect the enable access to this program checkbox for Internet Explorer
5. Click ok

The second way is to add a bogus proxy server to IE's Internet Settings. Follow these steps:

1. In IE, go to Tools>>Internet Options.
2. On the Connections tab, click the LAN Settings button.
3. In the resulting dialog box, select the following check box in the Proxy Server section: Use a Proxy Server For Your LAN (These Settings Will Not Apply To Dial-up Or VPN Connections).
4. Enter 0.0.0.0 in the Address text box.
5. Enter 80 in the Port text box, and click OK.

Good luck.
 
Thank you alot, I need a way that's more efficient than this. Why? because those members know how to reconfigure these settings , especially that any one on the network can access the net automatically.
 
Then you will need a server (domain controller) to apply a group policy.

The following explains this:
f you are in charge of a domain controller for a company, you can restrict Internet settings via Group Policy. Follow these steps:

1. On your domain controller, right-click the organizational unit that contains your domain users, and select Properties.
2. On the Group Policy tab, click Edit.
3. Expand User Configuration to set restrictions on a per-user basis.
4. Expand Windows Settings, and expand Internet Explorer Maintenance.
5. Select Connection, and double-click Proxy Settings.
6. Select the Enable Proxy Settings check box, add 0.0.0.0 to the HTTP entry, and click OK.
7. Expand Administrative Templates, and expand Windows Components.
8. Select Internet Explorer, and double-click Disable Changing Proxy Settings.
9. Select Enabled, and click OK.

If this is a network you've installed at a business, spend some money on a network specialist to come out and implement a network.
 
Eenable the Static DCHP

let say you only want 5 selected computers to have internet.. Once loged on, you may see an option to "Clone" or set up static DHCP.. this will bind the router selected IP with the mac address.

Then in the IP range, tell the router to only give out 5 ips. Now only those 5 computers with those Mac address's will have an IP for internet use.
 
learn something new everyday ... I thought mac filtering was for wireless only. Thanks man ... Im going to look into this myself.
 
I really appreciate your help, but do you know what the problem is ? the other PCs are in different houses,we are neighbors. Since we have a DSL subscribtion, I put some polices (as administrator) and one of them is that the user cannot use a switch and distribute the internet from his house. In case that happens I need a way to prevent unwanted PCs from gaining access to the Internet. I hope that I made it clear

I see that BuzzStPoing's way is more applicable, but I need more clarification, please.
 
Your neighbors are picking your signal and jumping on?

If you want to block this then enable WEP. you can enter a 64, 128 or 256 bit encrytion to block them from your wireless signal.

Now to help you further, What brand and model number of router do you have.

I mentioned that previously:
it is speedtouch 546 ,and it's not wireless

thanx
 
You're a little confusing on what you're asking. You want the 7 pc's to have internet, but no one else? If so, then the way to go is mac filtering. Your first post made it seem like this was all in one building, no wireless involved, and you wanted 4-5 pc to have internet but the other 2-3 not to.

In order to use mac filtering you will need to access each pc and write down each pc's mac address of the wireless connection adapter. To do this: go to Start>Run>type cmd>enter>type ipconfig /all. Locate wireless connection and find physical address. It will be something similar to 00:4B:3C:46:10:BB or the like.

After you have all the mac addresses of each pc, access your router and find where it allows you to input mac addresses for mac filtering, then enable mac filtering.
