在配置成控制器后往往都要出现wtime的问题原先不大注意但是还是有点烦人因此到microsfot support中找找还真找到了大家看看吧 x?scid=kb;ENUS;q&GSSNB= How to Configure an Authoritative Time Server in Windows (Q) The information in this article applies to: Microsoft Windows Server Microsoft Windows Professional Microsoft Windows Advanced Server Microsoft Windows Datacenter Server For a Microsoft Windows XP version of this article see Q SUMMARY This article describes how to configure an authoritative time server in Windows MORE INFORMATION Windows includes the WTime Time service tool that is required by the Kerberos authentication protocol The purpose of the Time service is to ensure that all computers that are running Windows or later in an organization use a common time The Time service uses a hierarchical relationship that controls authority and does not permit loops to ensure appropriate common time usage Windowsbased computers use the following hierarchy by default: All client desktop computers nominate the authenticating domain controller as their inbound time partner All member servers follow the same process as client desktop computers All domain controllers in a domain nominate the primary domain controller (PDC) operations master as their inbound time partner All PDC operations masters follow the hierarchy of domains in the selection of their inbound time partner Following this hierarchy the PDC operations master at the root of the forest becomes authoritative for the organization and you should configure the PDC operations master to gather the time from an external source This is logged in the System event log on the computer as event ID Administrators can configure the Time service on the PDC operations master at the root of the forest to recognize an external Simple Network Time Protocol (SNTP) time server as authoritative by using the following net time command where server_list is the server list: net time /setsntp: server_list There are several SNTP time servers run by the US Naval Observatory that are satisfactory for this function for example: ntpusnonavymil at tockusnonavymil at After you set the SNTP time server as authoritative run the following command on a computer other than the domain controller to reset the local computers time against the authoritative time server: net time /set More information about the net time command is available at a command prompt if you type the following command: net time /? SNTP defaults to using User Datagram Protocol (UDP) port If this port is not open to the Internet you cannot synchronize your server to Internet SNTP servers NOTE : Administrators can also configure an internal time server as authoritative by using the net time command If the administrator directs the command to the operations master it may be necessary to reboot the server for the changes to take effect Published Mar :AM Issue Type kbhowto Last Modifed Jan :AM Additional Query Words fsmo kbfaqwkds Keywords kbenv kbtool wfsmo kbFSMO |
