I have a very small domain with a single Domain Controller (Windows 2008 R2). Despite trying several things that I've read (such as w32tm.exe /config blah blah blah)...and stopping and starting the time service, and making sure that port 132 is open for incoming and outgoing messages on the Windows firewall, I am unable to get my PDC to sync up with a known NTP server. We just moved from a workgroup to a domain, and it was a lot easier when there was just an "Internet Time" tab on the "Adjust Date and Time" function, but with the domain, that tab went away. I get that all the computers in the domain will get their time from the PDC, but how to I sync up the PDC to my chosen NTP server (time.missouri.edu)? I'm looking for some specific, step-by-step instructions on how to make this work, so if you can point me to some that will actually work, I'd appreciate it.

Hi Scott , these might be useful for Windows 2008 Step 1: Net time /setsntp: W32tm /config /syncfromflags:manual /manualpeerlist: W32tm /config /reliable:yes W32tm /config /update W32tm /resync Pause Exit Step 2: [HKEY_LOCAL_MACHINE\SYSTEM \CurrentControlSet\Services\W32Time\Config] "AnnounceFlags"=dword:00000005 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters] "Type"="NTP" [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer] "Enabled"=dword:00000001 Step 3: Net stop w32time Net start w32time Net time Pause Exit Command in login script: Net Time \\<LocalTimeServer'sName /Set /Yes Regards.

Hi ScottDarth , Thanks for posting here. Please understand that by default all domain client computers will using PDC as their in-bound time partner. You may like to set external time source on PDC with following “Configuring the Windows Time service to use an external time source” which included in KB 816042. How to configure an authoritative time server in Windows Server http://support.microsoft.com/kb/816042 Thanks.

Hi Scott , Any updates ? Regards. Shafaquat Ali.M.C.I.T.P Exchange 2007 M.C.I.T.P Windows Server 2008 M.C.T.S OCS Server 2007 R2

No joy. I've followed the instructions but have yet to sync with the ntp server. My server is consistently almost 3 minutes slower than computers off the domain who synchronize directly with an NTP server listed on the 'Internet Time' tab.
