Default and Recommended Password Policy Settings
===============================================
Policy Default Recommended Comments
Enforce password history
24 passwords remembered
(No change)
Prevents users from reusing passwords.
Maximum password age
42 days
(No change)
N/A
Minimum password age
1 day
(No change)
Prevents users from cycling through their password history to reuse passwords.
Minimum password length
7 characters
(No change)
Sets minimum password length.
Password must meet complexity requirements
Enabled
(No change)
For the definition of a complex password, see "Creating a Strong Administrator Password" in the Establishing Secure Domain Controller Build Practices section.
Store password using reversible encryption
Disabled
(No change)
N/A
Default and Recommended Account Lockout Policy Settings
======================================================
Policy Default Recommended Reason
Account lockout duration
Not defined
0 minutes
The value 0 means that after account lockout an Administrator is required to reenable the account before account lockout reset has expired.
Account lockout threshold
0 invalid logon attempts
20 invalid logon attempts
The value 0 means that failed password tries never cause account lockout.
Because an account lockout duration of 0 minutes (administrator reset) is recommended, a small number for this setting can result in frequent administrator interventions.
Reset account lockout counter after
Not defined
30 minutes
This setting protects against a sustained dictionary attack by imposing a nontrivial delay after 20 unsuccessful attempts.
Default and Recommended Kerberos Policy Settings
================================================
Policy Default Recommended Comments
Enforce user logon restrictions
Enabled
(No change)
N/A
Maximum lifetime for service ticket
600 minutes
(No change)
N/A
Maximum lifetime for user ticket
10 hours
(No change)
N/A
Maximum lifetime for user ticket renewal
7 days
(No change)
N/A
Maximum tolerance for computer clock synchronization
5 minutes
(No change)
Maximum tolerance between the client's and server's clocks.
Default Domain Policy and Default Domain Controller Policy
The benefit of having a group policy on domain user account is that you as an administrator can set a restriction or limitation on your users.
Kerberos policy In Windows 2000, Kerberos policy is defined at the domain level and implemented by the domain's Key Distribution Center (KDC). Kerberos policy is stored in Active Directory as a subset of the attributes of a domain security policy. By default, policy options can only be set by members of the Domain Administrators group.

the policy is applied in the order of LSDOU local site->domain->then OU the poilcy applied will be of OU in the end
Microsoft recommends that access control to computer resources be administered by using groups. In this way, many users that have similar needs for resources can be dropped into a group that has the correct permissions already configured instead of individually modifying each user account. Group permissions to access resources are configured using group policy. A policy usually addresses one very specific aspect of a system's configuration. There are many policies that can be configured for a group to control system access and behavior. Local group policy addresses only users who are physically logging into one particular machine such as the server itself or a stand alone operating system. To log into a machine locally, a user must create a unique ID/Password pair that authenticates the local user to the local physical system. Once authenticated to the local physical machine, group policy according to which local group the user is assigned is initiated. Domain authentication as well as domain group policy is maintained centrally by the server for the domain. Even if a user has configured a local ID/Password pair for their local physical computer, a different and unique ID/Password pair is created to log onto the domain. When a domain user is created, they also must be assigned to a domain group. Once the server for the domain authenticates the domain user, the policy for the domain group the user belongs to is initiated. These policies are centrally administered by the domain administrator instead of each computer in the domain being configured separately for each user. Domain group policy can be configured to control access and behavior for any resource on the entire domain including resources on client computers. Local group policy can only control what is on the local machine at which a user is sitting. Finally, domain group policy supersedes any local group policy.

Domain Group Policy is an infrastructure inside of the Microsoft Windows operating systems (Windows Server 2000, 2003, and 2008, along with Vista) that allows the administrator to implement specific configurations for both computers and users. This infrastructure is what provides the centralized management and configuration for an Active Directory environment. Group Policy provides directory-based desktop-configuration management. With Group Policy, you can specify policy settings for registry-based policies, security, software installations, scripts, folder redirection, Remote Installation Services (RIS), and Internet Explorer maintenance. Admins use Group Policy to define specific configurations for groups of users and computers by creating Group Policy settings. These settings are specified by the Group Policy Object Editor tool and contained in a Group Policy object (GPO), which is in turn linked to Active Directory containers, such as sites, domains, or OUs. Domain Group Policy is the configuration of groups and users within a domain. In this way, Group Policy settings are applied to the users and computers in those Active Directory containers. Admins can configure the users
