This security setting determines whether a different account name is associated with the security identifier (SID) for the account "Guest." Renaming the well-known Guest account makes it slightly more difficult for unauthorized persons to guess this user name and password combination. Default: Guest. Note: This policy setting is not configured in the Security Templates, nor is a new user name for the account suggested here. Suggested user names are omitted to ensure that organizations that implement this guidance will not use the same new user name in their environments. Countermeasure: Specify a new name in the Accounts: Rename guest account setting to rename the Guest account. Potential Impact: There should be little impact, because the Guest account is disabled by default.
