Guest Cnews Posted July 19, 2008 Posted July 19, 2008 Hello After setting the time on the FSMO DC in a 2003 AD network of 3 DCs and 30 workstations, how long does it take to sync entire network. Do I need to run any other commands? Thanks CARl
Guest Meinolf Weber Posted July 19, 2008 Posted July 19, 2008 Re: Time service sync Hello CNews, Important is that the time source is the PDCEmulator. Did you configure it to use an external time source or just set the time on it? To configure it for an external time source you can use this: PDCEmulator: w32tm /config /manualpeerlist:peers /syncfromflags:manual /reliable:yes /update With "peers" you can set the time source, either DNS name (time.windows.com) or an ip address from a reliable time source. Here you can find some of them: http://www.pool.ntp.org/ To configure a client computer for automatic domain time synchronization w32tm /config /syncfromflags:domhier /update After that run: net stop w32time net start w32time Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties, and confers no rights. ** Please do NOT email, only reply to Newsgroups ** HELP us help YOU!!! http://www.blakjak.demon.co.uk/mul_crss.htm > Hello > After setting the time on the FSMO DC in a 2003 AD network of 3 DCs > and 30 > workstations, how long does it take to sync entire network.

Guest Bruce Sanderson Posted September 6, 2008 Posted September 6, 2008 Re: Time service sync I don't know if Microsoft has "officially" said that the net time command is deprecated or not, but for all practical purposes, I suggest it not be used any more. The w32tm command is the preferred way of configuring the Windows Time service. From what I have found out: net time /setsntp:ip_address or net time /setsntp:TimeServerDNSName (e.g. time.nrc.ca) is equivalent to: w32tm /config /syncfromflags:manual /manualpeerlist:ip_address /update or w32tm /config /syncfromflags:manual /manualpeerlist:TimeServerDNSName This tells the Windows Time service to synchronize the computer's time with a particular NTP server. net time /setsntp: is equivalent to: w32tm /config /syncfromflags:domhier /update This tells the Windows Time service to synchronize time using the Domain time synchronization hierarchy. For domain members (clients) this means synchronize with a domain controller. When a computer is joined to a domain, this setting is made automatically and there is usually no reason to change it. There should be one domain controller in the forest that synchronizes time with an external source. In a small forest, this is usually the domain controller of the root domain that has the PDC FSMO role.
