Network access: Do not allow storage of credentials or .NET Passports for network authentication This security setting determines whether Credential Manager saves passwords and credentials for later use when it gains domain authentication. If you enable this setting, Credential Manager does not store passwords and credentials on the computer. If you disable or do not configure this policy setting, Credential Manager will store passwords and credentials on this computer for later use for domain authentication. Note: When configuring this security setting, changes will not take effect until you restart Windows. Default: Disabled. Fix: (1) GPO: Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Network access: Do not allow storage of passwords and credentials for network authentication (2) REG: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa!DisableDomainCreds
