Time Synchronization

[1989]

ome of the computers on my network have the wrong time.
It's off by a few minutes....

So I changed the time on one machine. But after a reboot,
it goes back to the wrong time again.

So I figured it must be synch'ed with the server. I go
ahead and adjust all the clocks on the server. Then I
reboot a few workstations, and all is good. BUT after a
day or so (without rebooting the servers) all workstations
and servers go back to the wrong time.

Any ideas? TIA.

Are you using a Win2k server/AD?
IF so, you should set your server to sync with an internet time service
using

net time /setsntp:name.of.time.server

I've been using ntp2.usno.navy.mil but there are plenty out there. All
workstations should automatically sync to the DC.

It sounds like the server may be pointing to an incorrect time source. Follow this article to update the time source on the server.

Thanks for the link. But I'm still unsure as how to do
this.

On the server from the commandprompt:
net time /setsntp:time.nist.gov (or any other public timeserver)
net stop w32time
w32tm -once -v
net start w32time

On W2K/XP clients from the commandprompt (just once):
net time /setsntp:servername
w32tm -once -v

i did it, but the time is still off. do you
mean 'nist.time.gov'? and does this require a reboot?

 

[Marina Roos [SBS-MVP]]

It doesn't require a reboot. And time.nist.gov is a public timeserver. Do
you perhaps have ISA on the server too? Do you see any messages in the
eventlog about w32time?
Article 262680 has some more public timeservers.

Hi Marina and Rob. My name is Steven. I hope you both
don't mind I cut in this discussion. I do have a same
issue, but is only after I configure my server. In my
event log, I got event 11 and which is the ntp server
didn't respone. The time server I did test with are
time.nist.gov and time.windows.com any suggestion ?

Thanks,
Steven

Hi Steven,

That happens sometimes. It will try to synchronize later.

 

[Guest]

Thanks for your reply. Can you tell me what is the time
interval for synchronizion ?

Every 2 hours or something like that. You should be able to figure it out
with the w32tm/? command.
