Information

This policy setting prohibits users from connecting to a computer from across the network, which would allow users to access and potentially modify data remotely. In high security environments, there should be no need for remote users to access data on a computer. Instead, file sharing should be accomplished through the use of network servers. This user right supersedes the Access this computer from the network user right if an account is subject to both policies.

The recommended state for this setting is to include: Guests, Local account.

Caution: Configuring a standalone (non-domain-joined) workstation as described above may result in an inability to remotely administer the workstation.

Note: The security identifier Local account is not available in Windows 7 and Windows 8.0 unless MSKB 2871997 http://support.microsoft.com/kb/2871997 has been installed.

Users who can log on to the computer over the network can enumerate lists of account names, group names, and shared resources. Users with permission to access shared folders and files can connect over the network and possibly view or modify data.

Solution

To establish the recommended configuration via GP, set the following UI path to include Guests, Local account :

Computer Configuration\Policies\Windows Settings\Security Settings\Local Policies\User Rights Assignment\Deny access to this computer from the network

Impact:

If you configure the Deny access to this computer from the network user right for other groups, you could limit the abilities of users who are assigned to specific administrative roles in your environment. You should verify that delegated tasks will not be negatively affected.
