Time Sync

[Guest]

I want to be able to set a time on the main DC in our newtwork and ave all
dc's, member servers, and clients sync to this one server. Right now the
server and my worksation have two different times. Also is there a way to
set the time or sync the time with an external time source.

You must set this on the forest root DC which holds the PDC emulator role:

You can use the Microsoft time server (time.windows.com), but there are
others available for public use.

Hi George,

Windows 2000 fixes NT's lack of time synchronization by implementing a new
built-in system called Windows Time Service. This system requires almost no
administration. Workstations that run Win2K Professional and member servers
that run some version of Win2K Server set their system time and date to a
time and date that the domain controller (DC) that authenticates the
workstation or member server provides. But the workstation or server
doesn't synchronize its clock to the DC's clock only at authentication
time; the workstation or server resynchronizes its clock approximately
every 8 hours or whenever someone logs on.

For their part, the domain's DCs synchronize their time to one particular
DC in the domain that uses the Flexible Single-Master Operation (FSMO, aka
Operations Master) PDC emulator role. By default, the PDC emulator FSMO is
the first DC that you install in a domain. But what does each domain's PDC
emulator FSMO synchronize its time with? It synchronizes with the PDC
emulator FSMO of the first domain that you created in the forest (i.e., the
DC that acts as a PDC emulator FSMO in the forest root domain). That forest
root machine thus acts as the master clock and calendar for your entire
Active Directory (AD) forest. (For those who are wondering, yes, that
master timekeeper does understand time zones.)

Your question now probably is, How do I keep the top-dog master-clock
computer, the forest root's PDC emulator FSMO, in sync with time in the
real world? The answer is that you type in the command

net time /setsntp:
<servername>

You can use time.windows.com and the command now like: net time
/setsntp:time.windows.com

Thanks.
