Clock on windows server 2008 R2 standard x64

domain environment

win 2008 R2 Standard - PDC

issue:

Time on the server is off usually by 4 minutes.
time zone is correct.

When I change it to the correct time -
it reverts back to sometimes -3 or -4 mins.

how do I correct that ?

I followed these instructions

http://www.streetdirectory.com/travel_guide/114534/microsoft/how_to_configure_an_authoritative_time_server_in_windows_2008.html

and changed
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeParametersType to NTP

and
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesW32TimeConfigAnnounceFlags. to 5

and NTP server

from

time.windows.com,0x9

to

time.nist.gov,0x9

and that did not helped.

any options ?

thanks

Is this a VM? If so, there is a checkbox somewhere that synchronizes the clock with the underlying ESX server. If not, did you check the time on the System Board through BIOS?

ieden: It is NOT a virtual machine and nope I did not checked the BIOS clock yet as Im waiting for my maintenance window.

thanks for the links,
I'd like to use a network clock.

In the link above just check under
Configuring the Windows Time service to use an external time source

There's even a software so you don't mess with the configuration.

I've also noticed that VNC has a tendency to (for lack of a better term) "stop the clock" the processor is seized and you get a latency of upwards of 5 minutes...
One thing you might want to check is that your taskbar is not lying to you... Type "set" at a command prompt and see if the times match in the results with the taskbar.

ieden

sorry, "time" at the command prompt...

@jeden im not using VNC and taskbar clock is exactly the same as cmd>> time

I applied the registry fix from kb/816042 (Configuring the Windows Time service to use an external time source)

and the clock is still behind ( to be exact 58 seconds behind ) , Im comparing to other 2008 servers at different locations and cell phones.

Im using time.windows.com and tested out 2 other NTP serves. no results.

@sbarhoumeh
I guess the exact time won't never be equal, even some minutes of difference are OK.

So 58 seconds, I'm guessing, are just fine.

I wouldnt go by the time on a cell phone! They are nowhere near acurate.
Go here for a fairly realistic real time time.
