Allowing or preventing Internet access from a computer

Internet access is controlled by timed access control. If Internet access is prevented within a particular time period, all computers are prevented from accessing the Internet. If Internet access is enabled within a particular time period, a computer can only access the Internet if access has been enabled within the computer properties.

To allow or prevent Internet access from a computer

From the left-hand pane, expand Computers and choose All Computers.
From the right-hand pane, right-click the computer and from the menu, choose Properties.
On the General tab:

To enable Internet access, tick the 'Enable Internet access...' box.
To disable Internet access, clear the 'Enable Internet access...' box.

Click OK.

Note

You can use the same process to manage multiple computers. First select all the computers you wish to manage. If the tick is grey, some of the selected computers have Internet access enabled, and some have not.
