W32Time - 2003 Domain Controller

Dear experts,

I get this W32Time error on all of our domain controllers because apparently, my predecessor didn't do a great job. I checked the registry settings HKLM\System|currentControlSet\Servuces\W32Time\Parameters
  NtpServer = time.windows.com,0x1
  ServiceDll = c:\windows\system32\w32time.dll
  ServiceMain = SvchostEntry_W32Time
  Type = NT5DS

EventID: 0xC25A001D (29) - The time provider NtpClient is configured to acquire time from one or more time sources, however none of the sources are currently accessible. No attempt to contact a source will be made for 15 minutes. NtpClient has no source of accurate time.

And according to our networking guy we have an appliance that we used as a time server that is IP based. = 10.XXX.XXX.XXX

Can you please advise on how to fix this the right way? Thank you!

Do this on the domain controller (PDC) http://technet.microsoft.com/en-us/library/cc786897(WS.10).aspx

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

Do this on remaining domain controllers

w32tm /config /syncfromflags:domhier /reliable:yes /update

Do this on Windows clients  http://technet.microsoft.com/en-us/library/cc758905(WS.10).aspx

w32tm /config /syncfromflags:domhier /update


run this after each change

       net stop w32time && net start w32time

there is a NTP GPO that can be applied in AD that is very easy to configure.

Here is a shortcut what works immediately:

Open a command prompt, run these commands one at a time, it will sync within seconds
net stop w32time
net start w32time
w32tm /config /manualpeerlist:129.6.15.28,0x8 /syncfromflags:MANUAL /reliable:yes /update
w32tm /resync /rediscover
net stop w32time
net start w32time
Did the shortcut above work?
I object to closing this without awarding any points. I made a suggestion based on years server experience.  The author could have replied on my suggestion but didn't.
