This section provides information to help administrators who have been using User Manager to configure security policies in the past move to the new model of Group Policy for editing and configuring security policies.
Changing Password Policy for the Domain
To change password policy for the domain, open the Default Domain GPO from the Administrative Tools menu:
Click Start, point to Programs, click Administrative Tools, and then click Domain Security Policy.
In the Domain Security Policy console, expand Security Settings, expand Account Policies, expand Password Policy, and then select the policy you want to modify in the results pane. You can then make changes.
Changing Auditing Policy or User Rights for Domain Controllers
To change the Audit policies or User Rights defined for domain controllers, open the Default Domain Controllers GPO from the Administrative Tools menu:
Click Start, point to Programs, click Administrative Tools, and then click Domain Controller Security Policy.
In the Domain Controller Security Policy console, expand Security Settings, expand Local Policies, click either Audit Policy or User Rights Assignment, and then select the policy you want to modify in the results pane.
Changing local Password Policy on member Workstations or Servers (Non-Domain Controllers)
Because the Default Domain Policy GPO applies to all computers in the domain and because domain-level policies override local policy settings, member workstations and servers apply the Default Domain password policy settings to their local account databases by default. If this does not meet your requirements, then the permissions on the Default Domain GPO have to be reconfigured so that member computers that you do not want to receive this policy do not have the Apply Group Policy permission on the Default Domain GPO. After the permissions are configured so that the member computer does not have access to the default domain policy, local policy settings will no longer be overridden by the password policy settings defined in the Default Domain GPO.
To modify Local Password Policy security settings using the Local Security Policy UI:
Click Start, point to Programs, click Administrative Tools, and then click Local Security Policy.
In the Local Security Settings console, expand Security Settings, expand Account Policies, click Password Policy, and then select in the results pane the policy you want to edit.
Frequently Asked Questions about Security Settings Is it possible to define different account policies (Password, Lockout, or Kerberos Policies) for different OUs?
No. All domain controllers for a domain enforce the account policies that are defined in the Default Domain Policy. Domain controllers ignore password, lockout, or Kerberos policies defined at an OU or LGPO level.
After modifying a local security setting, the change does not take effect. What is happening?
The Group Policy model specifies that any policies configured locally may be overridden by like policies specified in the domain. The Local Security Settings UI lists the local security setting and the effective security setting for each policy item. (You can access the Local Security Settings UI by clicking Start, pointing to Programs, clicking Administrative Tools, and selecting Local Security Policy). If the effective security setting is different from the local security setting, it implies that there is a policy from the domain that is overriding your setting.
After modifying a domain-level-policy security setting, the change does not take effect. What is happening?
The Group Policy model applies domain-level policy changes periodically; therefore, it is likely that the policy changes made in the directory have not been made to your computer yet. To trigger a policy propagation on a local computer, type the following at the command line:
secedit /refreshpolicy MACHINE_POLICY
This will cause any changes made to domain-level policies to be applied to the local computer. To force a reapplication of policy to domain level policies, regardless of whether there has been a change or not, type the following at the command line:
secedit /refreshpolicy MACHINE_POLICY /enforce
You can determine whether or not security was applied successfully by viewing the Application Event Log. If an error occurred during the process of applying security policy, you can get detailed information by setting the following REG_DWORD to 0x02:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions\{827D319E-6EAC-11D2-A4EA-00C04F79F83A}\ExtensionDebugLevel
When this value is set, the Security Configuration Engine (SCE) will log policy-processing information in the Winlogon.log file at %windir%\Security\Logs\Winlogon.log.
What is the Add Workstation to Domain Logon right, and how does it relate to delegating similar permissions on the directory?
The Add Workstation to Domain user right is supported for applications that use downlevel SAM (Security Accounts Manager) NET APIs to create computer accounts. Users that have this right are allowed to create 10 computer accounts in the Active Directory Computers container using these down-level APIs. When a user creates a computer account using this user right, the Domain Administrators group becomes the owner of the computer object. Note that this right is not recognized when LDAP is used to create computer accounts.
In Windows 2000, the recommended way to allow a user or group to create computer accounts is by granting that user or group the permission to Create Computer Objects on the desired container. This can be accomplished in the Active Directory Users and Computers snap-in via the Delegation Wizard or through the Security tab on the Properties page of the container. When a computer account is created using access control permissions, the actual creator of the object becomes the owner of that object.
Note: The create-computer-object permission should not be granted indiscriminately. Allowing users to create computers in the domain is similar to allowing users to create user accounts in the domain. Unlike Windows NT 4.0, Windows 2000 computer objects can be used to do network authentication and, hence, to access resources over the network. Users that have access permissions to create computer objects are also not subject to any quota restrictions. That is, they can create any number of computer accounts.
The best security practice would be to grant only trusted users (by using a group) the permission to create computer objects. At the time the computer object is created, the creator can define which users are allowed to use that computer object to join their physical computer to the domain.
