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

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

=> w32tm /config /manualpeerlist:peers /syncfromflags:manual /reliable:yes /update

Where is difference if I use at PDC:

net time /setsntp:ip_address_of_sntp_server

Also, I've setup all my client computers with:

net time /setsntp:""

Without that, I've always get W32time sync errors.
 
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.

It is perfectly useless to know the right answer to the wrong question.
