The Password complexity is a Local Policy setting named “Passwords must meet complexity requirements” under Computer Configuration/Windows Settings/Security Settings/Account Policies/Password Policy.
In a Server Core installation, there is no graphical user interface to set this policy.
Instead, use secedit to import and export the security settings from a Full Installation of Windows Server 2008 and later versions.
- First export your security configuration using the following command:
secedit /export /cfg C:\securityconfig.cfg
- Then open notepad.exe and edit the C:\securityconfig.cfg file.
Under [System Access] you should find PAssword complexity = 1
Change the value to 0 and save the file.
- You can also modify policies like Minimum Password Age, Lockout Duration, etc.
- Then fire up the next command to import the configuration:
secedit /configure /db C:\Windows\security\new.sdb /cfg C:\securityconfig.cfg /areas SECURITYPOLICY
