2.3.10.8 Configure 'Network access: Remotely accessible registry paths and sub-paths' is configured - Network access: Remotely accessible registry paths and sub-paths is configured
Information
This policy setting determines which registry paths and sub-paths will be accessible over the network, regardless of the users or groups listed in the access control list (ACL) of the winreg registry key.Note: In Windows XP this setting is called 'Network access: Remotely accessible registry paths,' the setting with that same name in Windows Vista, Windows Server 2008 (non-R2), and Windows Server 2003 does not exist in Windows XP.
Note #2: When you configure this setting you specify a list of one or more objects. The delimiter used when entering the list is a line feed or carriage return, that is, type the first object on the list, press the Enter button, type the next object, press Enter again, etc. The setting value is stored as a comma-delimited list in group policy security templates. It is also rendered as a comma-delimited list in Group Policy Editor's display pane and the Resultant Set of Policy console. It is recorded in the registry as a line-feed delimited list in a REG_MULTI_SZ value.
The recommended state for this setting is:
System\CurrentControlSet\Control\Print\Printers
System\CurrentControlSet\Services\Eventlog
Software\Microsoft\OLAP Server
Software\Microsoft\Windows NT\CurrentVersion\Print
Software\Microsoft\Windows NT\CurrentVersion\Windows
System\CurrentControlSet\Control\ContentIndex
System\CurrentControlSet\Control\Terminal Server
System\CurrentControlSet\Control\Terminal Server\UserConfig
System\CurrentControlSet\Control\Terminal Server\DefaultUserConfiguration
Software\Microsoft\Windows NT\CurrentVersion\Perflib
System\CurrentControlSet\Services\SysmonLog
The recommended state for servers that hold the Active Directory Certificate Services Role with Certification Authority Role Service includes the above list and:
System\CurrentControlSet\Services\CertSvc
The recommended state for servers that have the WINS Server Feature installed includes the above list and:
System\CurrentControlSet\Services\WINS
Rationale:
The registry contains sensitive computer configuration information that could be used by an attacker to facilitate unauthorized activities. The fact that the default ACLs assigned throughout the registry are fairly restrictive and help to protect the registry from access by unauthorized users reduces the risk of such an attack.
Impact:
None - this is the default behavior. However, if you remove the default registry paths from the list of accessible ones, remote management tools such as the Microsoft Baseline Security Analyzer and Microsoft Systems Management Server could fail, as they require remote access to the registry to properly monitor and manage computers.
Note: If you want to allow remote access, you must also enable the Remote Registry service.
Solution
To establish the recommended configuration via GP, set the following UI path to: System\CurrentControlSet\Control\Print\Printers System\CurrentControlSet\Services\EventlogSoftware\Microsoft\OLAP Server

When a server holds the Active Directory Certificate Services Role with Certification Authority Role Service, the above list should also include: System\CurrentControlSet\Services\CertSvc.
When a server has the WINS Server Feature installed, the above list should also include:
System\CurrentControlSet\Services\WINS
Default Value:
