This policy setting determines which network shares can be accessed by anonymous users. The default configuration for this policy setting has little effect because all users have to be authenticated before they can access shared resources on the server. Note: It can be very dangerous to add other shares to this Group Policy setting. Any network user can access any shares that are listed, which could exposure or corrupt sensitive data. Note: 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. Countermeasure: Configure the Network access: Shares that can be accessed anonymously setting to a null value. Potential Impact: There should be little impact because this is the default configuration. Only authenticated users will have access to shared resources on the server.
