how to prevent guest user to access internet

hi to all,

i'm new member here.

currently i want to share my computer to be access by guest user. but, i don't want guest user could access internet. please help me to how to do that? thanks..

 

By default in XP Home and XP Pro the Guest user has no internet access.
There are workarounds involving registry changes and Fast User Switching.
But they are relatively obscure.

.

 

but if my computer using LAN connection to access internet, Guest user still could access it. How to prevent Guest user to access internet without disconnect LAN access?

 

Two methods:

First, User a false proxy server. You can easily lock down the already limited Guest permisssions to prevent editing these settings.

Note: The false proxy is computer is a Computer not User change. You will have to use the User Logon script to revert the changes for non-Guest users.


Second method, use IPSEC
This is appropriate on a machine basis, not user basis.

Third Method, Using Netsh.exe

You can use Netsh.exe to set nonsensical TCP/IP addresses, Gateways, etc.
Since the Guest Account is not a member of the Group Network Configuration Operators, they will be unable to make changes to the settings.

Example:

netsh interface ip set address name= "Local Area Connection" static 127.0.0.1 255.255.255.0 127.0.0.1
