Hello, can anyone help me or teach me how to disable Internet Connection of a workstation running on Windows XP from Windows 2003 server when the user login to domain?
I don't know if this is posible but I am novice in Windows 2003 server administration.
Any help would be highly appreciated.
Thank you very much.

You can do it many ways. I prefer to just remove the DNS forwarder and set the DHCP to only use the local DNS. They can still get to web pages if they know the IP Address though.

I think the best way is to not do this with Windows but with the network. You can setup a proxy server which will give you better control and block internet on the local firewall.

If all of network users are member of users group on their computer and not administrators, they can't change computer's network settings. So you can remove their default gateway or if you use DHCP, reserve their MAC and specify no gateway for them.
But the best way of doing that is to use a third party firewall or bandwidth managing software such as kerio winroute, ISA server, Bandwidth manager, Wingate.

Thank you. But that is another problem for me how to set DNS or DHCP.

I want to restrict per user who is allowed to use the internet and not allowed. Even they login to the same computer workstation.

Because some department we have is 2 or more user for 1 computer.

Yep you will need to setup a Proxy Server for that then limit who can access it.

If you don't want to setup a proxy then you may also be able make OUs for each Users Group and create GPOs under each OU then in the GPO set the Windows Firewall to block port 80. This is a lot of work but if you want to be granular this is what you have to do.
