Discussion Help with NTP Server in 2008R2

    Hello,

    We had an authoritative time server configured on Server 2008 Ent. Also we applied the NTP client settings via group policy. Recently we moved the NTP server to 2008R2 and made changes on the GPO so that the clients have to get time settings from the new server. I used the 'fixit' from the below document to configure the same in 2008R2 to obtain time from an external source. http://support.microsoft.com/kb/816042 . The Server is syncing with time.windows.com. But now the clients are not getting the time from the server 2008R2. When I run the command 'w32tm /resync' It is saying 'Sending resync command to local computer The computer did not resync because no time data was available.'  How do I troubleshoot this?  Please help me out.

    Regards,

    Tony

    try to use w32tm /query /source  to view wich source is added.

    look at http://technet.microsoft.com/en-us/library/cc773263(v=ws.10).aspx to other parameters.

    Hello,

    When I initiated the command w32tm /query /source it shows 'Local CMOS Clock' as the source in client machines. And in NTP server it is 'time.nist.gov,0x1'. The problem is, 2008R2 is not advertising itself as an NTP  server. I changed these registry settings to make it as an NTP Server:

    1.) HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\ AnnounceFlags value modified to 5

    2.)HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer Enabled value modified to 1

    3.)Restarted time services net stop w32time & net start w32time

    I also tried a hot fix from http://support.microsoft.com/kb/816042. But neither not working.

    Also find the output of the below commands:

    C:\Users\admin>w32tm /monitor
    R2xxxxxV002.xxxx.com[[::1]:123]:
        ICMP: 0ms delay
        NTP: error ERROR_TIMEOUT - no response from server in 1000ms
    R3xxxxxx024.xxxx.com *** PDC ***[192.168.4.26:123]:
        ICMP: 72ms delay
        NTP: error ERROR_TIMEOUT - no response from server in 1000ms

    C:\Users\admin>w32tm /resync
    Sending resync command to local computer
    The computer did not resync because no time data was available.

    Can anyone help me out please.

    Regards,

    Tony

    Did you turned off the firewall?
