Network access: Restrict anonymous access to Named Pipes and Shares
When enabled, this policy setting restricts anonymous access to only those shares and pipes that are named in the Network access: Named pipes that can be accessed anonymously and Network access: Shares that can be accessed anonymously settings. This policy setting controls null session access to shares on your computers by adding RestrictNullSessAccess with the value 1 in the HKLM\System
\CurrentControlSet\Services\LanManServer\Parameters registry key. This registry value toggles null session shares on or off to control whether the server service restricts unauthenticated clients' access to named resources. Null sessions are a weakness that can be exploited through shares (including the default shares) on computers in your environment.
