Adjusting time on PDC emulator

[flyersix]

I have found the time on the 2003 DC holding the PDC emulator FSMO
role to be off by roughly 7 minutes. This machine is set to use its
own CMOS clock for the time source.

Can i just adjust the time from the taskbar to correct the time for
all the machines in the network?

Your PDC emulator should be getting its time from a reliable time source.
The default is time.windows.com. To check your PDC, issue
%windir%\SYSTEM32\NET.EXE TIME /QUERYSNTP
from the command line or run dialog.

To set it to use time.windows.com, issue
%windir%\SYSTEM32\NET.EXE TIME /SETSNTP:time.windows.com
from the command line or run dialog.

With the time source set, issue
%windir%\SYSTEM32\NET.EXE TIME /SET /YES
from the command line or run dialog.

When you shut down normally, the time service should reset the hardware
clock to the time on the software clock.

The default of time.windows.com does work well enough, and is a much better
option the joining the crowd beating on any of the well-known statum 1 time
servers. For other alternatives, http://time.windows.com redirects to an
interesting ntp project, and you can find an appropriate ntp pool.


There are some great articles on this on the Microsoft website.

Yes that will work. You can also set the PDC to sync its time from the
internet as per the following article:

I sugget not using the net time command - use w32tm instead. Also, there is
no need to edit the registry manually.

On the Domain Controller with the PDC FSMO role, use these commands:

w32tm /config /manualpeerlist:peers /syncfromflags:manual
/reliable:yes /update
w32tm /resync /rediscover

for the word "peers", substitute the time source of your choice (e.g.
time.nrc.ca or time.nist.gov).

After issuing these command, check the System Event Log for entries from
Source: Time-Service - you should see log entries reporting success.

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

I would rather not use an external clock for my time provider. My
main concerns where only that the client pcs' have a fairly acurate
time source and they be able to login (time stamp issue).

The PDC emulator is handling the time server role well. It is just
off a few minutes as is every machine on the network. I was hoping
for advise on wether changing the time from the task bar on the PDC
emulator would correct everyones time without creating login errors
for the other machines.

Hello flyersix,

The machines are having the same time as the PDCEmulator in a domain. So
chagne the time on the PDEmulator and all clients should update there own.
If firewalls are used, NTP port 123 UDP has to be open.

Best regards

You should not correct your PDC clock more than five minutes from the client
clocks, or the clients will not be able to use Kerberos authentication.

CMOS clocks are cheap and inaccurate. Your PDC should be getting its time
from an reliable time server.
