Procedure: Creating a Group Policy object
In this demonstration, you will learn how rename the Administrator and Guest accounts on all computers in the domain by using Group Policy objects.
To create a Group Policy object, perform the following steps:
1. Click Start, point to Administrative Tools, and then click Group Policy Management.
2. Navigate to the domain in which you want to rename the Administrator and Guest accounts.
3. Right-click the domain, and then click Create and Link a GPO here.
4. In the New GPO dialog box, type Account Rename Policy and then click OK.
Procedure: Configuring To configure the Group Policy object settings to rename accounts, perform the the GPO settings to following steps:
1. With the CPMC console still open, right-click the Account Rename Policy GPO and then click Edit.
3. Double-click Accounts: Rename administrator account.
4. On the Security Policy Setting page, select Define this policy setting, type <name> (where <name> is non-intuitive name for the account), and then click OK.
5. Double-click Accounts: Rename Guest account.
6. On the Security Policy Setting page, select Define this policy setting, type <name> (where <name> is non-intuitive name for the account), and then click OK.
7. Close all open windows and restart the computer for all changes to take effect.
Time Synchronization Process
*****************************illegal for non~trainer use ******************************
Introduction In Windows Server 2003, the W32Time service synchronizes clocks by using the Network Time Protocol on UDP port 123.
Time synchronization Time synchronization uses the following process to ensure that all computers process within an organization are synchronized.
1. The primary domain controller (PDC) emulator operations master in the forest root domain is the authoritative time source for the organization. First the PDC emulator is configured to use an external stratum 2 time server. The default NTP time server is configured to use time.microsoft.com. All PDC operation masters in other domains in the forest follow the hierarchy of domains when selecting a PDC emulator to synchronize their times. For example, child domains will synchronize with the domain above them in the domain hierarchy.
Note Stratum 1 time servers are servers that are synchronized directly with atomic clocks. They are generally used to synchronize stratum 2 time servers, which are exposed for public use. For more information about stratum servers, see http://www.ntp.org.
2. Next, all domain controllers in a domain synchronize their times with the PDC emulator operations master in their domain as their inbound time partner.
3. Finally, all member servers and client desktop computers use the authenticating domain controller to synchronize their clocks.
Important Although the default configuration is acceptable, in high security environments it may not be advisable to use an external source for time synchronization. Handheld Global Positioning System (GPS) units synchronize their clocks in the same manner as stratum 1 and 2 time servers. A handheld GPS can be configured to provide time inputs into the PDC in the forest root domain.
