Allow configuration of connection sharing
Computer Configuration\Administrative Templates\Network\Network and Dial-up Connections
Determines whether administrators can enable, disable, and configure the Internet Connection Sharing feature of a dial-up connection.
If you enable this policy or do not configure it, the system displays the Sharing tab in the Properties dialog box for a dial-up connection. On Windows 2000 Server, it also displays the Internet Connection Sharing page in the Network Connection wizard. (This page is available only in Windows 2000 Server.)
If you disable this policy, the Sharing tab and Internet Connection Sharing wizard page are removed.
Internet Connection Sharing lets users configure their system as an Internet gateway for a small network. It provides network services, such as name resolution, to the network.
By default, Internet Connection Sharing is disabled when you create a dial-up connection, but administrators can use the Sharing tab and Internet Connection Sharing wizard page to enable it.
This policy appears in the Computer Configuration and User Configuration folders. If both policies are configured, the setting in Computer Configuration takes precedence over the setting in User Configuration.
This policy applies only to users in the Administrators group.
This policy was documented incorrectly on the Explain tab in Group Policy for Windows 2000. The Explain tab misstates the name of the Sharing tab.
