Wants limited access over internet via server

Hello,

I would like to know is there any way by which i can have a limited access over internet? I have two nic cards in my computer and wants to choose specific computers on the network which can have direct access on the internet. I have installed Windows xp on all computers. I have given them admin rights but no one is using password on their computers. I want only some specific computers to access the internet. I'm using a switch for connecting all computers. Can any one help me out how can i do so?

Thanks..

Create IP and domain name restrictions. To do this, you must create an ".htaccess" file with the restricted directories.

This limit access can be done through usernames and passwords. To limit access by a username and password you must first define users or sets of users by creating access groups. Next, you can create an ".htaccess" file that specifies these users or groups.

An easy way to control access to web pages on your site is to use .htaccess files. These can be used to password-protect an entire directory, but not individual files within the directory.

The .htaccess file, which resides inside the restricted directory, alerts the web browser of the restriction and determines if a given username is authorized to view the directory. If the username is correct, it passes the authorized user on to the password file.

Another good option with you is to create a proxy server,depending on how much users you have? You can search for proxy on Google website. There are lots of free trial version that you can try for.

Hope so this might help you out to resolve the problem.
