So user GPs would not apply and additionally the settings that I'm working with are found in computer configuration.
Code:
Network access: Allow anonymous SID/Name translation
Network access: Let everyone's permissions apply to anonymous users
Network access: Do not allow anonymous enumeration of SAM accounts
Network access: Do not allow anonymous enumeration of SAM accounts and shares
I set the group policy and checked it with Group Policy Results. I looks like it should work.
