Windows 2008 time issue

1. Log in to your PDC Server and open the command prompt.
2. Stop the W32Time service: C:\>net stop w32time
3. Configure the external time sources, type: C:\> w32tm /config /syncfromflags:manual /manualpeerlist:"0.pool.ntp.org, 1.pool.ntp.org, 2.pool.ntp.org"
4. Make your PDC a reliable time source for the clients. Type: C:\>w32tm /config /reliable:yes
5. Start the w32time service: C:\>net start w32time
6. The windows time service should begin synchronizing the time. You can check the external NTP servers in the time configuration by typing: C:\>w32tm /query /configuration
7. Check the Event Viewer for any errors.

WHAT IS THE TIME SERVICE

The Windows Time service (W32Time) provides network clock synchronization for computers without the need for extensive configuration.

The Windows Time service is essential to the successful operation of Kerberos version 5 authentication and, therefore, to AD DS-based authentication. Any Kerberos-aware application, including most security services, relies on time synchronization between the computers that are participating in the authentication request. AD DS domain controllers must also have synchronized clocks to help to ensure accurate data replication.

The Windows Time service is implemented in a dynamic link library called W32Time.dll. W32Time.dll is installed by default in the %Systemroot%\System32 folder during operating system setup and installation.
