WN25-SO-000020 - Windows Server 2025 must prevent local accounts with blank passwords from being used from the network.

Information

An account without a password can allow unauthorized access to a system as only the username would be required. Password policies must prevent accounts with blank passwords from existing on a system. However, if a local account with a blank password does exist, enabling this setting will prevent network access, limiting the account to local console logon only.

Solution

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> Security Options >> Accounts: Limit local account use of blank passwords to console logon only to 'Enabled'.
