Guest Domon Posted July 25, 2008 Posted July 25, 2008 Hi Currently, my servers are having some issues with w32time. My servers are not syncing with the time source (a server 2003) and event id 50 and 36 are logged. We set them to sync in a 12 hr interval. Can anyone advise on the possible causes to this problem? Could it be the time source or the interval?

Guest Meinolf Weber Posted July 25, 2008 Posted July 25, 2008 Re: w32time Hello Domon, Do you have a domain or workgroup? In a domain the PDCEmulator is the time source, all other DC's sync with this machine and member/client machines sync with one available DC. It's common practise to sync the PDCEmulator with an external time source and the clients will automatically sync with one of the DC's. 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/ Client configuration: 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 > Hi > > Currently, my servers are having some issues with w32time.

Guest Domon Posted July 26, 2008 Posted July 26, 2008 Re: w32time Hi The servers are standalone servers, not domain servers. This problem has cause us some headache as the application can only works if the server's time difference is less than 60 sec. I wonder if increasing the synchronisation frequency like once in 6 hr will helps. Or is it the time source that we need to change the configuration? The time source (another server) will sync with another external time source while all servers in the tier will then sync with it to update their time. I new in configuring NTP. So, pls correct me if I am wrong.

Guest Bruce Sanderson Posted July 27, 2008 Posted July 27, 2008 Re: w32time In a workgroup, by default, each computer independently synchronizes its time with an Internet time source - the default is time.microsoft.com. There should be entries in the System Event Log with Source of Time-Service indicating whether the time synchronization was successful and with what time source. It's probably a good idea to use a single server as the time source for all the other servers if you aren't doing so already; this may ameliorate your problem. The default settings for time synchronization will usually keep the time on all the servers within a second, so a difference of over a minute would be quite unusual. To configure the time service on the computer that will serve as the time source for the others, use these commands: w32tm /config /syncfromflags:manual /manualpeerlist:time.nrc.ca /update w32tm /resync /rediscover Note that I'm in Canada and choose to use time.nrc.ca as the Internet time source (manualpeerlist in the above command). You might want to use a different time source that is nearer to you - see for example http://support.ntp.org/bin/view/Servers/StratumTwoTimeServers and http://support.ntp.org/bin/view/Servers/WebHome. You should see entries in the System Event Log indicating that the time service has successfully synchronized after the resynch command. On the other servers, configure them to use the one configured above (in the commands, this computer is called TimeSource.mine.local): w32tm /config /syncfromflags:manual /manualpeerlist:TimeSource.mine.local /update w32tm /resync /rediscover The w32tm command has a number of options for monitoring and diagnosing time synchronization issues, but I've not had a need to explore them - it usually just works! Use the command: w32tm /? to get a list of the options with desriptions. Note that different versions of Windows Server support different options for the w32tm command. For example, the /query option is available in Server 2008 but not Server 2003. -- Bruce Sanderson http://members.shaw.ca/bsanders It is perfectly useless to know the right answer to the wrong question.
