This security setting determines whether a different account name is associated with the security identifier (SID) for the account Administrator. Renaming the well-known Administrator account makes it slightly more difficult for unauthorized persons to guess this privileged user name and password combination. Default: Administrator. Note: This policy setting is not configured in the baseline, nor does Microsoft suggest a user name for the account. Suggested user names are omitted to ensure that organizations that implement this guidance will not use the same new user name in their environments. Counter Measure: Specify a new name in the Accounts: Rename administrator account setting to rename the Administrator account. Potential Impact: You will have to inform users who are authorized to use this account of the new account name. (The guidance for this setting assumes that the Administrator account was not disabled, which was recommended earlier in this chapter.) Fix: (1) GPO: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Accounts: Rename administrator account (2) REG: ### (3) WMI: ###
