Can't get NTP time working on SErver 2008 R2 DC

[guest]

I'm having a nightmare setting up the NTP time on our Server 2008 R2 Domain. All our servers are on Hyper-V, but for the PDC at least I have unticked the "Time synchronisation" Integration Services Management box, so I know the time is not coming from the source.

On the PDC Emulator I ran this command:

w32tm /config /manualpeerlist:"0.uk.pool.ntp.org 1.uk.pool.ntp.org 2.uk.pool.ntp.org 3.uk.pool.ntp.org" /syncfromflags:manual /reliable:yes /update

and

net stop w32time && net start w32time

This runs succesfully, but the time doesn't change (12 mins slow at the moment)

When I run "w32tm /resync /rediscover"
I get:
-------------
Sending resync command to local computer
The computer did not resync because no time data was available.
--------------

and when I run w32tm /query /status
I get:
------------------------
Leap Indicator: 0(no warning)
Stratum: 1 (primary reference - syncd by radio clock)
Precision: -6 (15.625ms per tick)
Root Delay: 0.0000000s
Root Dispersion: 10.0000000s
ReferenceId: 0x4C4F434C (source name: "LOCL")
Last Successful Sync Time: 26/01/2010 12:50:47
Source: Local CMOS Clock
Poll Interval: 10 (1024s)
-------------------------

So as you can see the Local CMOS is still the source.
Can anyone help me? It's driving me nuts.

Please make sure you have followed all the suggestions below to setup the time server.

How to configure an authoritative time server in Windows Server

Note: Virtual Machine will always sync with Hyper-V host at startup. This is required to boot strap the timer inside the virtual machine.

If the issue persists, try the suggestions below:

Currently, I suggest correct the time on Hyper-V host (sync its time with time server) and restart the VM so that it could get correct indirectly.

It seems your PDC cannot contact the external time server to get correct time. If so, it will query local CMOS clock instead. Please try to disable Firewall to test.

If the issue persists, let’s try to monitor the network traffic when trying to sync time:

Download Microsoft Network Monitor and install it on PDC.

1. Run Network Monitor and start capturing. Run w32tm /resync /nowait
2. Reproduce the problem.

Stop the capturing, save the resultand use Windows Live SkyDrive (http://www.skydrive.live.com/) to upload the file. If you would like other community member to analyze the report, you can paste the link here, if not, you can send the link to tfwst@microsoft.com.

Also, did you run " w32tm /query /status" on client systems? What’s the result?
