PDC will not sync with external time source (NTP) using w32time

i consistently getting errors w32time service on pdc. have gone through registry in detail make sure set correctly. (using win2003 sp2)

 

i following error in event viewer: (event id 36)

 

the time service has not synchronized system time 86400 seconds because none of time service providers provided usable time stamp. time service no longer synchronized , cannot provide time other clients or update system clock.

 

to make sure connecting time server of choice (ntp.okstate.edu) used command:

w32tm /stripchart /computer:ntp.okstate.edu /samples:3

 

this returned:

 

c:\documents , settings\stevent>w32tm /stripchart /computer:ntp.okstate.edu /s
amples:3

so i'm connecting , getting time stamp. yet when attempt force resync w32tm /resynch /rediscover, system tells me me this:

 

microsoft windows [version 5.2.3790]
(c) copyright 1985-2003 microsoft corp.

c:\documents , settings\stevent>w32tm /resync /rediscover
sending resync command local computer...
the computer did not resync because no time data available.

c:\documents , settings\stevent>

 

i'm kind of @ loss of why occuring. thought @ point gpo overiding this, windows time service gpo set "disable." correct?

 

any ideas out there?

 

 

 

rediscover have computer @ lan time server. you'll need set ntp.okstate.edu source. find documentation w32tm here: http://technet2.microsoft.com/windowsserver/en/library/b43a025f-cce2-4c82-b3ea-3b95d482db3a1033.mspx?mfr=true and under config-area in table you'll find commands.

 

 

 

w32tm /config [/computer:<target>] [/update] [/manualpeerlist:<peers>] [/syncfromflags:<source>] [/localclockdispersion:<seconds>] [/reliableyes|no)] [/largephaseoffset:<milliseconds>]

computer:<target> – adjusts configuration of <target>. if not specified, default local computer. update – notifies time service configuration has changed, causing changes take effect. manualpeerlist:<peers> – sets manual peer list <peers>, space-delimited list of dns and/or ip addresses. when specifying multiple peers, option must enclosed in quotes. syncfromflags:<source> – sets sources ntp client should synchronize from. <source> should comma separated list of these keywords (not case sensitive): manual – include peers manual peer list. domhier – synchronize domain controller (dc) in domain hierarchy. localclockdispersion:<seconds> – configures accuracy of internal clock w32time assume when can’t acquire time configured sources. reliableyes|no) – set whether computer reliable time source. this setting meaningful on domain controllers. yes – computer reliable time service. no – computer not reliable time service. largephaseoffset:<milliseconds> – sets time difference between local , network time w32time consider spike.
